[acoustic relic]

is this something you code in HA or in the ESP?

because for the SmartIR, this json file is on the HA, and the integration just reads from that file and sends the command directly to GPIO14 to the ESP device, son on the ESP there is only 1 line of code that in theory sends an input command through GPIO14

[rugged harness]

This is a base64 format. I guess you can use this to convert into raw format https://github.com/elupus/irgen#raw Then in ESP, use the remote transmitter to transmit via your GPIO14 pin https://www.esphome.io/components/remote_transmitter.html#remote-transmitter-transmit-raw-action

[small goblet]

If it's always on certain days with exceptions for holidays, there's a custom component that handles that well. Much easier than scraping a web site

[gray heath]

Is there anything that would prevent me from putting a z-wave dimmer or switch module inside the actual light fixture itself or something, rather than behind the light switch as all the installation guides suggest?

[uncut kernel]

You can put it anywhere you want. Location has pro and cons. In your case, the cons would be that you will still news that Noone touches your dumb switch, or the light fixture would love power. Otherwise you would need either to bypass the switch, and add a smart switch, which controls the switch module, or just block access to the switch. In that case I would say it makes more sense to have smart bulbs, so you could have access to rgb colors.

[gray heath]

I mean connecting the dumb switch and wiring it in the same way the diagrams say to, just doing that at the fixture or whatever instead of in the switch backbox to avoid the limited space and get access to neutral wires

[cerulean oracle]

So when could i expect an update?

[surreal sparrow]

You can expect all you want. Not going to help. Try actually following what it says to do and checking the documentation. You cant miss it. It's bright red at the top of the page.

https://esphome.io/components/light/fastled.html

[cerulean oracle]

Must've been added recently. I checked that page a few months ago when the issue first popped up

[timid rune]

Anybody here can help me set up the panel controls for my MQTT light? I would also like some advise if I should change the MQTT topics I use, I want to write my code properly.
info:
control board: wemos D1 mini with custom code using pubsubclient for MQTT
mosquitto MQTT broker running
control MQTT topics: /wemos/led/red with data: 0-255 (same for all colours and fade speed)
status MQTT topics: /wemos/led/redstate with data 0-255
at the moment I can control the lights with static on/off values, but I don't know how to set 0-255 sliders for the colours (or is there a colour selector I could use?)
I am new to HA and this is the first device I am creating and setting up.

[lilac shadow]

https://www.home-assistant.io/integrations/light.template/

[timid rune]

The colour_template here seems to only support HSV and I need RGB, also it still does not answer how I can add sliders or colour selector to the dashboard.

[lilac shadow]

I'm thinking color template gives you the slider

And set_color can be used make buttons to pick the color

Maybe you can use node red to convert between hsv and rgb

[undone arch]

Have I done a big miss in getting the ST7789 display that isnt the ST7789"v" version ? I cannot get it to work as it doesnt appear to have the SPI pins (mosi and clk)

[ancient wedge]

Has anyone here taken on this:

https://github.com/openshwprojects/OpenBK7231T

I've got a WiFi-controlled smart valve I was hoping would arrive with an ESP8266 embedded, but it has the BK7231T.

For my particular set of skills it would probably be easier to just swap it out for the ESP8266, but I would prefer to use the included controller but not sure exactly where to solder UART for flashing.

[river spruce]

Anyone here use or know about the raspiaudio muse proto? I wanted to add an RFID reader, I was wondering if it could handle it or would use too much of the esp32 resources?

[ancient wedge]

Compute resources or simply powering the RFID board? I would think either would be fine, the RFID board isn't going to draw much of either.

[river spruce]

yeah, thanks. I am ordering one and I will try to see if I can get it to work with rc522, if not I'll use it the precompiled way.

[smoky smelt]

Can someone quickly explain the mmWave stuff? Is it so accurate that it can detect even the tiniest of motion like breathing which is why it's useful for presence tracking?

I saw that the graphs indicate they get less accurate on the edges of the FOV and at distance so I guess that's how they work

I also saw a Texas Instruments video showcasing how they can be used to calculate where exactly the movement is. This must be some sort of a triangulation thing, and I wonder if these are available just yet for DIYers?

[sand leaf]

looking to possibly switch from a pi4 to a mini pc (x86) for home assistant. Can anyone link me to recommendations? Have read a few articles online, just curious to see what others are actually using

[ancient wedge]

Watch this video first:

https://www.youtube.com/watch?v=Leru0rCS8b0

Then this one:

https://www.youtube.com/watch?v=VEqWlOeJ2YA&t=1s

Short version of the story is that yes, they are super accurate with the right software and even the DIY version is expensive (~$50) at the moment.

[smoky smelt]

Cool, might have to try this stuff out

[zealous nacelle]

If a voltage converter outputs 0volts is that effectively "off", or would an actual on/off switch be better?

I was thinking that I might be able to pull off just setting the potentiometer to 0v, this is for a desk fan

[rugged harness]

Any specific reason to shift? I run kubernetes cluster with several containers and rpi4 is just fine. Running 24x7 does not hurt in power segment as it hardly takes more than 7w even at peak

[burnt lagoon]

@sand leaf I havent watched the video yet but maybe it will be right for you https://www.youtube.com/watch?v=uAxe2pAUY50

It's very cheap, maybe you have to upgrade the ram but i think it will do

[sand leaf]

I need my pi 4 for another project. And want to shift to a ssd

[sand leaf]

Thanks I’ll take a look

[rugged harness]

Well if that project is in a container than test it out on rpi forst. Ssd on pi does not give great speed if you are expecting that

[hollow raptor]

Anybody know why my temperature sensor outside would spike every morning at the same time?

It happens roughly at 8:30 daily

They're ESPHome based

With shct3 temperature sensors

[gray heath]

Where is the sensor, does it have anything near it like a boiler or anything that might be coming on first thing in the morning?

[upbeat dust]

Perhaps it catches first sunlight at that time?

[hollow raptor]

Nope it's outside on a covered patio

So I don't think it's sunlight either

[gray heath]

Could still maybe be from the light if maybe that area gets super bright or warm from the sun or something first thing in the morning

[hollow raptor]

Hmm I'll experiment with putting something in front of it

[dreamy junco]

hi have a look on ebay etc for refurbished/used Lenovo M series tiny PCs, Dell Optiplex Micro PCs, HP elitedesk PCs.. look for something with a relatively new CPU (i3-6XXXT) and you should be ok.. the one suggested in Wolfgang's channel is a thin client rather than an actual mini PC.. which to me isn't really worth switching over an RPi

[dreamy junco]

is there a way to swap sensors or add another one at the same location to check if it's that particular sensor's fault?

[hollow raptor]

Yeah I can swap it with a different one

I have 3 identical sensors

[dreamy junco]

that's what I would do.. maybe put another one side by side in the same location.. would be interesting to know what the problem is though (if it isn't a sensor issue) 🙂

[mighty hatch]

Can I ask an ESPHome question here or is there a better place?

[smoky smelt]

ESPHome has their own Discord as well but people here use it too

[rugged harness]

Maybe UFO passes through that time , this definitely explains the exhaust plumes of a donnager class stardrive 😃 seriously, check if the esp is restarted during that time and it is just a initial temp setting

[naive sand]

I have some pi0w's and some ESP32's i want to use for some sensors. I'm assuming ESPHome is the way to go for the ESP's. What's recommended for a raspberry pi? MQTT? It's going to be mostly environmental sensors like temp, voc, pressure, humidity, P2.5. I want the data displayed as graphs under indoor and outdoor.

[stray fossil]

Does anyone happen to know of any project to get custom firmware on the Amazon Smartscales (dash smart shelf’s) and hook them up to home assistant?
I have a few sitting around I don’t have a use for anymore, and would love to do something like… put it under my automatic cat food or water to get an alert (or something else) when either are low.

I tried searching around and the only weight anything I found for home automation was someone monitoring 3D printing spools.

[lilac shadow]

python the takes the data and publishes it to mqtt

[narrow jasper]

Simple networking question

I’m building a house, and everyone always recommends running extra cat6 everywhere. I agree, especially since I will have a lot of aeotec multisensors I’d like to feed power to over poe (with poe to 5v adapter naturally), but most of these will be in the ceiling/ high walls. What I’m wondering is, when people recommend running cat6 everywhere, where does it end up in the room? Do you get a cat6 connection somewhere in the wall ceiling? Are the cables just available behind the wall/ceiling for when you need them one day, and then you make a hole to get connected?
Then how do you decide where in the room to place it?

[heady cairn]

So, I had an idea, and hopefully this is a good place to brainstorm

I'm setting up a projector with a widescreen ... screen (2.35 aspect ratio)

The projector can adjust the lens, so when watching 16x9 content, it fills the height of the screen, but has black bars on the left and right.

When watching movie content (2.35 etc), it zooms out and adjusts the image such that the black bars are off the screen above and below, and the image fills the entire screen

This is a manual step when streaming content on something like an Nvidia shield

I want to do it automatically, so here's what I'm thinking:

1. Periodically screengrab the android device using ADB over the network

2. Scan that image to figure out where the completely black areas are and output an estimated aspect ratio

3. Take that stream of aspect ratios, and somehow toss outliers, creating a stable value

4. When that value changes for x seconds, adjust the projector to match (This is already taken care of via an integration).

Any ideas for any of that?

[pulsar holly]

I built a pir sensor from a d1 mini clone and a hc501, its mostly stuck on reporting detected. Ive swapped the jumpers around, checked connections, played with the sensitivity and time out, cant seem to figure it out

Tried a diff usb brick and cable

I made another that seems to be working better but records lots of false positives

[karmic saffron]

Hey all, is there a generally accepted preferred Airconditioner/Heat pump brand that integrates with Home Assistant? I see that Daikin deprecated there integration 😦

[quick swift]

You could also use an app like Tasker or something to take the screenshot, but if ADB is easier than that might be simpler to get the screenshot onto another device. I don't know the specifics about how to get the aspect ratio, but the two things that come to mind are to use OpenCV with Python to detect the aspect ratio of the content, or possibly ffmpeg/ffprobe to get the aspect ratio.

1. Feed image to python script
2. Process
3. Send API command to Home Assistant to fire integration to adjust projector

[smoky smelt]

If you use a player like Kodi you can probably easily get the aspect ratio of the video @heady cairn. I have automations based on he content length, type etc and it's pretty great

what you're thinking will probably work fine but I would first look for simpler and more bulletproof alternatives

[heady cairn]

I was hoping to use the metadata from Plex and Jellyfin, but it reports the file aspect ratio, not the aspect ratio of the inner image.

[smoky smelt]

Oh right that wouldn't work for a lot of content unfortunately

[ancient wedge]

What's the jumper set to, L or H?
Are you giving it 3.3V or 5V? (needs 5V)
Did you play around with the sensitivity and/or Time delay pots?

https://www.mpja.com/download/31227sc.pdf

[pulsar holly]

Tried both H and L jumper. Its getting 5v from the wemo output. Tried with the pots

Some reports on the internet say these components have issues because of noise / interference but this is beyond usable so i dont understand

[ancient wedge]

Hey, I have a Daikin and use their One PLUS thermostat which is terrible but it is integrated with Home Assistant. Recently another user on here pointed me towards their azai6wspdkc (the last character can be A B or C, but you want C) it has WiFi control and a local API.

[ancient wedge]

Next step is to try a different ESP with the same PIR, and the a different PIR with the same ESP...I got a batch of 12 Wemos D1 Mini clones recently and I've come across one dead one so far.

I actually wonder if it's the connection to the board that's bad and I need an ESP8266 for a transplant anyway, so I'm going to try using the "dead" one.

[ancient wedge]

Still looking for someone who's done this OpenBK7231T flash.

[karmic saffron]

Thanks @ancient wedge. Not sure its available in my region (Oceania) but looks pretty good, its either Daikin or Mitsubishi at this stage. Looking to buy some new units and somehow retrofit the old fujitsu

[bronze token]

I use a sensibo

[karmic saffron]

Sensibo is definitely cool ! But they don't have 2 way communication right?

[pulsar holly]

Yeah i guess all there is to do is more trouble shooting. Problem is, I made 3 of these and each one has an issue

1 constantly detected, one continuously detected/clear, 1 most accurate but about 3 false positives an hour which is just useless

Some comments on msg boards talk about soldering a ceramic resistor b/c its probably noise

[ancient wedge]

Oddly enough, I just put together an ESP32 and PIR sensor today as well...using ESPresense though

[pulsar holly]

Hmm i didnt even realize the d1 has bluetooth

[ancient wedge]

The D1 is an ESP8266, I was simply referencing the PIR project I also took on today, but mine was on an ESP32 which has BT.

So no, the D1 does not have BT.

[pulsar holly]

Oh ok

[sick copper]

Hi im looking for someone to help me with a add-on for my central heating Company they have an API for looking up your consumption, I need thes translated in to an hack integration
Someone willing to help me? I have no experience with programming

[dreamy junco]

There's an ESP32 version of the D1 mini though

[ember hollow]

You can share a bit more as the question is too high level ...not guaranteeing I can help but ...

[sick copper]

Basically it is this API but it is only provided in danish
https://aalborgforsyning.dk/erhverv/energioptimering/datadeling-for-fjernaflaeste-varmemalere/api-for-adgang-til-malerdata/

[ember hollow]

That is fine but... I see the eksempel with two blocks. What do you want to achieve? Read all or just a part of them?

What you will be trying to achieve is using the RESTful integration of HA, which requires a url to the api kicking back a json value (along the format on the page). In the restful integration you can then define if you need sensors and with what attrbutes

if you already have the json for your needs then you could share this here (obfuscating any private details as ID/name/etc) and then we'll take it from there

[rugged harness]

If you don't mind controlling via IR, the esphome works great and seamlessly integrates with HA. Building a esp based remote is cheap. Been using for all my aircons from long time https://www.esphome.io/components/climate/climate_ir.html

[surreal sparrow]

They only depreciated local control of the BRP069C4x wifi adapters. You can still purchase models with A or B designated adaptors that work fine. And you can fit the BRP072A42 adaptor to newer machines that specify the BRP069C4x. Many people have.

[karmic saffron]

Thanks for the informative replies @rugged harness and @surreal sparrow I appreciate it. Looking to get as close to plug and play with my new systems as possible! Will probably have to go the esphome route for my existing fujitsu! I didn't know about the reciever option - that's great.

[surreal sparrow]

Plugging a BRP072A42 adaptor in instead of a BRP069C4x is not only way easier (especially if you get the installer to do it) but it reports the actual state of the device rather than relying on hopefully intercepting IR signals. The adaptors plug right in. They are not expensive.

I am biased though, I hate stateless IR control. I have eliminated it from my house.

[karmic saffron]

I totally understand the hate for stateless - I want to avoid it as much as possible.

Are you using Daikin?

[surreal sparrow]

Yes

[karmic saffron]

I definitely will be getting the installer to add the module - it'll be a mate of mine.

I think you've won me over for the new systems I'll have to check out the BRP072A42 availability in Australia.

$171 AUD - Certainly not as cheap as ESPHome, but much cheaper than the $350 odd the fujitsu adaptor is and I dont think that supports a local API

[surreal sparrow]

What model are you considering? Most of the Aus models are still supported. It's only the Euro ones that aren't.

[karmic saffron]

I literally am looking at a blank canvas, just want the best integration with Home Assistant. From your advice I've been led to Daikin Cora - but if you have any specific models I'm all ears. Will be three separate outdoor/indoor units

[rugged harness]

Exactly, I wish I could say 170+ as cheap 😃 I use this IR( ir led + esp + adapter) and it costs less than 5 . Since I always operate on this and almost situated next to aircon. using various ikea buttons or even voice to control hence State is not a problem

[surreal sparrow]

I just had a 6kW Daikin Zena installed. The adaptor that it comes with supports local control. They're more expensive than the Cora but quieter, which is what I wanted for my cinema.

The Cora supports the BRP072C42 which has local control.

[karmic saffron]

Damn $5 is good. I only have one problem with the stateless control, family and friends! Having said that if I got the automation just right so they never touched the controls....

[rugged harness]

Just use 1 automation setting which reset a setting. Then you are back to square one and everything is fine.

[karmic saffron]

Where do you have that IR USB sitting so it has LOS to the AC?

[karmic saffron]

Is there much of a muchness between say BRP072C42 and BRP072A42 from a HA perspective?

[rugged harness]

You can actually spend 10 and use esp32. The ble control will also allow any ble based buttons as well. You don't even need WiFi then

[surreal sparrow]

Nope. Both have the same functions. Everything but swing control (leave it on auto).

[rugged harness]

The range is almost 15 feet for me. Hence ther eis always a switch either near or just beneath

And my zigbee ir device is already ready just that ther are no compact zigbee sticks with pin outs

[karmic saffron]

Can I just say this is my first real interaction with the HA community and it has been a great experience, thanks both.

[rugged harness]

https://duckduckgo.com/?q=cc1352R&t=fpas&iax=images&ia=images&iai=https%3A%2F%2Fdocs.zephyrproject.org%2Flatest%2F_images%2Fcc1352r_sensortag.jpg is quite huge for my liking but a works on AAA battery

I am trying to make it work on Nordic dongle with button cell strapped in

[karmic saffron]

Thanks for your help @surreal sparrow almost certainly going to go with the Daikin either Cora or Zena, maybe Cora for the office and Zena for the bedroom. Do you keep your Wifi adaptors restricted from the internet to prevent future bricking of local control or no concerns there?

[surreal sparrow]

Yes, local network only. Auto updates disabled.

[karmic saffron]

so @rugged harness , how long did it take you to put together.

[rugged harness]

The esp-01 in 10 mins. Esp32 about 20 I would say. Let me me know if you need the yaml for the esp

and is working for ages now I guess

[karmic saffron]

Do you have it on Github per chance? wouldn't mind a peek.

[surreal sparrow]

You can try the IR. For the price it's no biggie if you find it lacking and update to the Daikin controller later. Though the Zena comes with the adaptor included I think.

[karmic saffron]

I'll definitely be trying IR for the pre-existing Fujitsu I've got

[rugged harness]

Nope, but it is so common that it there everywhere. It just literally 2 lines that you could fine in esphome link I gave

[karmic saffron]

But I figure if I'm buying a new one for other parts of the house I might as well try and make it as easy as possible, not to mention "voting with my wallet" so to speak

as vendors certainly dont have to allow local APIs, I'll check if the Zena includes the adaptor, makes the price difference more favourable.

Yep Zena has wireless as standard - wish the prices weren't so obfuscated

So the BRP072C42 is priced at $185 odd and the price difference between the Cora and Zena appears to be about $250 so good value for sure.

[rugged harness]

I was wondering why you were asking about how much time. Then it hit me that you might be thinking you need to solder all that caps and resistors. No, it is a plug in adapter https://www.amazon.com/10Gtek-ESP8266-Adapter-Compatible-Arduino/dp/B09K3XDS1T/ref=mp_s_a_1_2_sspa?keywords=esp-01+adapter&qid=1655988121&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzRjdENlBYSkdDN1ZKJmVuY3J5cHRlZElkPUEwMzMyNzQwMTA4VUlWSzhBN0YxMiZlbmNyeXB0ZWRBZElkPUEwODY1MjAyMURBV0lBR0VDMUIzUyZ3aWRnZXROYW1lPXNwX3Bob25lX3NlYXJjaF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl for esp01. Only ir led you need to solder. But if going for eap32, ypu don't even have to do that as esp32 are generally devkit with microusb

[karmic saffron]

Mate you are spot on! Thats exactly what I thought

[rugged harness]

And you nudge you further to try this. You can pair it with a temp and humidity sensor that you can keep it anyway. This will work with esp 32 as it is ble https://esphome.io/components/sensor/xiaomi_ble.html#lywsd03mmc

The best part is that this temp humidity sensor (~ $6) connected to that esp32 hosting ir led can be kept at that corner where you want specific temp control 😃

and write esphome automation to regulate. So that even if your wifi goes down, it is still working

[karmic saffron]

Thanks for all your knowledge I’ll be using it going forward - might look into zigbee like you mentioned earlier

[hollow raptor]

So I now have a bunch of PC soundbars (govdeals)

I want to turn them into a speaker system for my garage

They've got 12V power inputs and 3.5mm audio inputs. I can deal with both of those easily

My question is, what should I use to control them?

I could just plug the speakers into an echo dot or something but that's a bit proprietary for my liking

[blazing token]

you can use one off this

you can then install squeezelite on it

[bleak cargo]

anyone made a hidden TV with a servo motor that FLIPS UP. I wanna mount a TV under a seat that flips up 90 degrees in a bay window seat......

I think im going to use a linear servo motor but Id like feedback so it doesnt over extend AND I dunno how to mount the TV horizontally so that it doesnt fall when its horizontal....

Only a small TV (32") so its not going to be too heavy

[bleak cargo]

alternately - anyone got a recommendation for a 32" display (like a tablet)

[sinful skiff]

has anyone here set up raspi with opensprinkler for use with home assistant? tackling that project today... 😉

[ancient wedge]

I think you could build a frame using Unistrut and then bolt the TV to it using the VESA mounting holes. To do this project right, I think you're going to need some welding skills...It may be easier to have one that rises vertically out of a cabinet, you could build an elevator of sorts...But then I just did a quick search for "motorized tv mounts", maybe look there for inspiration?

[shy rapids]

Any non-adjustable VESA wall-mount should do just fine.

I would assume the servos need to be pretty beefy to hold up the weight of the TV while closing, so it doesn't just slam down.

There's also something like this that you could use to simplify the whole thing a bit:
https://www.amazon.com/VIVO-Electric-Motorized-Pitched-Ceiling/dp/B01GGR6I24

Then all you'd need to get motorized is the actual lid (or have the TV push the lid out the way :D)

[bleak cargo]

Unfortunately a rising situation isnt possible as the void that the TV needs to rise from is a structural concrete 6ft x 6ft beam

maximum depth is 100mm

[bleak cargo]

too deep.

[peak gorge]

Hi, i just came across this video: https://www.youtube.com/watch?v=BOgy6QbfeZk and will like to try something similar, but would it be possible to power the micro from the power of the ct clamps itself? so it all gets self powered? (I have a split phase, so it will be 2 ct clamps)

pretty sure that that's not how it works

figured I'd try here first since it's a multi-purpose diy device. but hopping over to there. ty 👍🏻

Just saw that the Pi Pico W just came out, apparently ESPHome support is already in the works, Looks like it may be a good alternative to ESPHome devices? I've been planning to get some boards for a while, but so many different models/versions its confusing, at least with the Pi Pico W I know its going to be good quality and dont have to stuff around with finding a good version of an ESP board?

My understanding is that the Pico sits somewhere between the ESP8266 and ESP32? And the ESP8266 is more than enough for most ESPHome uses?

[rough tiger]

I don't know where to start and ask about this but I have a relay that is controlled with 433mhz RF. Is there a simple way to add wifi support or replace it with wifi? Using a nodemcu or something like that

[gray juniper]

No but i use a tasmota 8 ch relay with HA and Irrigation Unlimited integration for 2 years now in my garden works great .https://github.com/rgc99/irrigation_unlimited

[lilac shadow]

Does anyone know what this button on the back of the shelly 1pm is for? There isn't anything in the manual about it.

[ancient wedge]

Does it just toggle the relay manually?

[lilac shadow]

no, I tried that

it looks like it is tied to the ext_rstb on the ESP8266EX based on some pictures I found

[ancient wedge]

LED?

[lilac shadow]

it does have an LED in the same spot too

looks like that

[ancient wedge]

Yeah, probably just the reset...

Start pinging it and hit the button and see if you lose packets

Any chance you speak Arabic?

[cerulean kite]

Hi, I'd like to have a go at a diy setup. Something that would be useful is relay control ideally 2. What do I need for this sort of proof of concept? an adapter usb to serial? say this, (the blue one?) https://www.aliexpress.com/item/32273550144.html

there is just so much kit! or maybe? or both? https://www.aliexpress.com/item/1005001884283888.html

for the relay maybe this? https://www.aliexpress.com/item/32825211851.html

I need to use aliexpress as I am in NZ, there isnt any other sane choice.

Hello, i have a esphome node with a bme280. It worked perfectly fine for over a year. But now im getting the following message: (Message skipped because it was too big to fit in TCP buffer - This is only cosmetic)

Out of the 4 attributes only 1 sends it correctly, the altitude, temp, humidity and pressure dusplay that message

Does anyone know how to resolve this?

[dapper crown]

Hello everyone! 🙂

I'm currently using HomeAssistant with MySensors. I've built a few sensors that are using RFM69W radios to communicate with the gateway via the MySensors protocol.

There are a few sensors I'd like to build that don't require being away from the gateway (a Raspberry Pi). Is there a way to connect a sensor directly to the gateway and talk to it via I2C or SPI?

For intance, I'd like to add a BME280 to have pressure displayed on HomeAssistant, or connect my alarm system with a bit of extra hardware (potentially an ATMEGA328P)

[lilac shadow]

you can connect a bme280 to a pi directly

and use some python to take the data and report it over mqtt

then add an mqtt entity to HA

[dapper crown]

Nice idea 🙂

[lilac shadow]

I would use a cron job to have it update at the interval you want

[dapper crown]

I could push the data directly from a Python script actually

cron would be a good idea though

[lilac shadow]

I was thinking cron could run the python every x minutes

[dapper crown]

@lilac shadow : I wired the BME280 directly on the Raspberry Pi, installed the mosquitto MQTT broker, wrote a script that reads the sensor and publishes the data to MQTT and configured HomeAssistant...

And IT WORKS! 🙂

[gray juniper]

@dapper crown @lilac shadow You can also use a pi and use MQTT-IO to add sensors, PIR, and switches to it. It will publish to a broker to. I use this setup for my garage doors and reed sensors to show open status I added a PIR and BME280 sensors for environmental stats. Seem to be easier for me to manage than writing a Python script. https://github.com/flyte/mqtt-io

[lilac shadow]

nice

yeah that's much better than making your own script

[gray juniper]

it is a simple yaml file for the connected devices and intervals are easy to set.

Inbuilt WiFi antenna on esp32 any good or will I want an external in order to get a halfway decent signal? Also is the going rate for them around 7-8 quid?

I'm UK btw

how far are you thinking - i think it should be ok within a small apartment? and 7-8 quid sounds about there.. depending on where you get it from.. you might be able to get it from banggood or aliexpress for cheaper when it's on sale?

[spare rose]

Thanks. Across the garden - I've got a long range access point in the house and the little smart plug just gets a signal, Just a question of how good the esp32 antenna ks

Ordered stuff to try my ffc cable approach. Reckon I'll need to put the end of the cable in potting compound to avoid ice bridges?

[vagrant pulsar]

So far I was always using an ESP8266, because for my small projects it was always enough. But now I have to use an analog input on the ESP8266 (Wemos D1 Mini).

Yesterday I found out that reading the analog input on a regular base and using the WIFI/mqtt results in broken wifi/mqtt connections.

I have found that this a known issue on the ESP8266. So I'm going to upgrade to an ESP32 board because the problem should not be there what I have read so far.

But I have some questions about uploading the code. I'm using PlatformIO and c++ on the ESP8266. On the Wemos D1 mini you don't have to press some buttons to come in the DFU mode.

On the Wemos S2 mini and Wemos C3 mini I see that you have to press buttons to enter the DFU mode.

Is this something specific of the ESP32 chips or the ESP32-S2/ESP32-C3 chip or something of the Wemos board?

When my board is in my casing it have to open it everytime to upload new code. At the end I want to have OTA update (and I assume that you don't have to press the buttons to come in DFU mode 🙂 )

But i'm wondering why you have to press those buttons on the Wemos ESP versions and not on the Wemos D1 mini (ESP8266)?

[naive sand]

Does the yaml templates support calling CLI commands? I've decoded some rf signals with rfcat and i want to create templates to trigger them to control things like my rf doorbell when my wifi doorbell is triggered.

it would basically be calling a python script with some arguments depending on what i want to trigger

oh nmi think i found it https://www.home-assistant.io/integrations/python_script/

[dapper crown]

Sweet! 🙂

[plain crow]

ESP8266-based solar powered wifi irrigation valve: https://github.com/cybershoe/moist-controller

It was sitting half-finished for months, finally got it up and running and dampening plants.

[gloomy galleon]

nice dude

[plain crow]

Thanks, it's been mostly done since last fall, but I hadn't gotten around to actually finalizing it until this weekend.

I didn't really appreciate how much standby power a lot of components take until I needed to figure out how to make it last 24 hours without a lot of guaranteed sunshine each day.

[gloomy galleon]

sounds like a good learning experience then 😛

[plain crow]

Indeed. I got bit by the low-power bug, now I have another project percolating to make a MQTT-connected live-catch mousetrap that will let me know when catch a mouse.

That one uses the ULP on the ESP32 and sips something like 10µA.

I've validated all of the individual components for that one, I just need to set aside some time to integrate it and write some code.

But based on my math it should last a few months between charges on a 500mA LiPo

[gloomy galleon]

haha

are you able to use esphome with that or just making your own sketch?

[gloomy galleon]

ya i've never played with the low power core but seen some cool projects on youtube using it

[plain crow]

That's MQTT with esp-idf

[gloomy galleon]

googles

[plain crow]

The ULP wakes up every 100ms or so and pulses an IR LED and looks for the voltage spike on the photodiode

If it doesn't see the spike then it's blocked by a mouse, so it wakes up the main processor, connects to WiFi, publishes a MQTT message and then goes back to sleep.

[gloomy galleon]

does it need to wake up that often?

[plain crow]

I don't know how fast a mouse can move, so I figured 10Hz was enough to make sure I detected it coming through the gate.

(This is a live-catch trap)

[gloomy galleon]

ah

[plain crow]

But this is the ULP that wakes up, not the main processor.

So it's minimal current draw.

If it were a kill trap, I'd only need to know about it before it started to smell.

[gloomy galleon]

hah

[plain crow]

But a live-catch trap is only live-catch if you can relocate and release before the mouse dehydrates.

So that's the use case.

[gloomy galleon]

my cat says that's a waste of a good mouse

[plain crow]

If they actually ate them I woudn't mind.

But they just leave them in our bed.

Not on.

[gloomy galleon]

mine does.. but scares me some day he'll eat one that got poisoned

[plain crow]

in.

[gloomy galleon]

ya mine will bring me the half he doesnt want

[plain crow]

Yeah, and we are lucky enough to live next to a biome edge that's just within the legal trap and release radius for wildlife, so we can actually let them go somewhere where they have a fighting chance.

[gloomy galleon]

yeah nothing wrong with that

[plain crow]

Right now I have an always-on version that's PoE powered that I threw together in a few hours one night, but it's limited by being close to a network port.

[gloomy galleon]

not a bad setup tho

PoE for life 😛

[plain crow]

It does the job, but I want something that's small enough and has long enough battery life that I can just charge it up, toss it in the pantry or attic or wherever we think they are, and not have to worry about forgetting to check it every 12 hours.

[gloomy galleon]

yeah

plus a fun project

[plain crow]

The irrigation valve gave me enough experience designing custom boards that I think it should be very achievable.

I did a prototype 3d-printed enclosure with a firebeetle board and a few pieces of brass tubing for the LED/photodiode stalks that attaches to the lid of a tin cat trap

And I know all of the electronics work

It's just a matter of finishing the integration

But I have a day job and it's been on my To-Don't list for a while too.

[gloomy galleon]

I looked into pcb design and it’s interesting but not for me

Digital logic wasn’t my favorite class lol

[plain crow]

I don't do it often, but I enjoy obsessively optimizing a design every once in a while.

[keen harbor]

If you do low power it's likely you have seen this but I'll link it anyways. https://www.thingsquare.com/blog/articles/sensortag-power/

[plain crow]

Yep, that’s the method I’m going to use for my soil moisture monitors

The mousetraps needs more real-time sensor monitoring, hence the ULP

[pale vine]

Has anyone tried building an ESP smart speaker from ESP + an ADC / speaker? Which components did you use? I would like to build one like what Marcelo showed during the YouTube for Out Loud since it had a rotary encoder too

[crimson lichen]

easy ideas for something standalone and low profile that can simply beep when a contact is broken beyond a certain threshold, maybe on a timer?

have coworkers that keep leaving a door ajar that cannot be left open for reasons.

[ancient wedge]

you could play audio on a Google Home Mini perhaps...may not be small enough for you

[clear falcon]

hello there,
Can you help me spot the issue?
There is an input gpio, and there is an output gpio.
If the pressure valve (it is a pressure sensor) turns on, the pump should turn on, and if the pressure valve turns off the pump should turn on. But the pump does nothing, probably the issue is on the automation, cause if I turn the pump on "by hand" from the ui it works, and ui also shows the correct state of the pressure sensor.

Hi All, just wondering if anybody has played around with using home assistant for a car? I've got HA running at home and it's great... so great that I've decided to give my VW Transporter the same treatment! I've got a Teltonika RUT955 which will be my MQTT broker, RS485 interface and vpn back home to my HA server (the plan is that the van with just get a separate dashboard on my existing HA server - I'd actually prefer to have a separate server on a raspberry pi in the van, but connecting the HA phone app to two different instances at once doesn't seem to be an option). So far I'm looking to manage battery state, dehumidfy (I surf a lot so ideally, I'd like to dry my wetsuit in there so I don't have to keep taking it out of the car) remote lock/unlock, nfc tag lock/unlock (keep a tag in each of my wetsuits or leg ropes!). Also considering seeing if I can log info from the CAN bus - could be fun!
If anybody has done any of this before I'd be interested in any gotchas/tips etc, or if not, I'm interested in any other ideas you may have!

[ebon swan]

You can definitely connect mobile app to 2 instances. I have it that way. (so to have 2 HA servers)

I have one instance in parents house and one in my flat. You just need to switch between them in app after you will launch it. (I use iOS app but i have also Android tablet with HA app which was connected to both of my instances)

[marble yarrow]

Hi there, I'm looking for a thermometer for my swimmingpool that I can read in HA from BLE or ZigBee. Anyone got any reference or DIY setup for this ?

[mystic shell]

Do you mean by changing the external (I'm using SSL so no internal URL to worry about)? That might be alright for visiting family but going from the van to the house is a pretty regular occurrence, and there's some overlap (I want to be able to open my garage from the van and the house)

[ebon swan]

I dont use it externally. I know it is possible but i dont trust it.

I mean in “app” there is settings > companion app > add server

Do you really need to have HA accessible externally ?
And If you have iphone you can have homekit connection and open garage from homekit. And no external access is needed. And if you really would need full HA i would say VPN to home network.

I am unsure about Android.

[ebon swan]

If you really want to go diy then ESP32 (ble) + DS18B20 (plastic watterproof one) + EspHome

[mystic shell]

I didn't know you could do that! Unfortunately that's iOS only - hopefully it'll get added to android soon. RE security, SSL plus my randomly generated very long password is pretty decent. 2FA would be great to have... And I just checked and it's available! I should really read the release notes once in a while... I'll be adding that shortly. My password manager can deal with 2FA codes so no issues from me there :)

[mystic shell]

I have a pool with a regular thermometer. I'm now realising what an oversight this is! I'll add it to my list of projects...

A water level sensor would be great to pop in the same package come to think of it...

[ebon swan]

Because of you I am going to check because of you if its iOS only feature (I have some Android phones around)

[ebon swan]

okay you are right -> https://github.com/home-assistant/android/issues/296

currently it is only on iOS (don't know why) tested on my own
But you could trick it

You could try to download "beta" release (if its different package) then you could have 2 HA apps in phone. Or if you your device has something like "work profile" you still can have 2 same apps installed

[lethal thicket]

Hi all. im piggy backing off a Tuya chip right now to replicate functionality. Does anyone know how a wake command or a ping for status?
or am i losing the tx because of piggy back
thanks

[marble yarrow]

hey hey, good point. I will reboot the Solar WS project of Debasish Dutta (https://www.pcbway.com/project/shareproject/Solar_Powered_WiFi_Weather_Station_V3_0.html) I've order 5 PCB card. Just need to buy some extra chip !!!

[ebon swan]

Looks neat but it does much more then just "get temperatur from pool" 😄

[marble yarrow]

sure but the goal is to reuse the solar part. I've already built the WS on my roof 🙂

[mystic shell]

I think just running the one instance using VPN as i'm currently planning would be a less clunky solution for me. I try to keep as much automation as possible on my devices and using MQTT, so HA is more a pretty front end. If it can't connect back home it's not a massive deal - things will still work

[ebon swan]

Maybe just try #android-archived if somebody is planning implementation of that GH issue 😄

that would be perfect

[proper magnet]

Working on implementing an FSR bed occupancy sensor using an aqara door sensor, but then got to thinking that if I have to have two strips to cover the width of the bed, I should set it up to tell who is in bed, other than using 2 door sensors or going to the work to use an xbee, is there anything off the shelf I could mod? Hacking the aqara sensors is very convenient for cheap battery operated projects, be nice if there was something else out there with two inputs.

[surreal sparrow]

Aqara sensors expect a switch input. The FSR may not have a high enough resistance to register as "off" or a low enough resistance to measure as "on". The best way to do this is with the analogue inputs of an ESP32. There's a write-up on the community forum.

https://community.home-assistant.io/t/fsr-the-best-bed-occupancy-sensor/365795

[proper magnet]

Thanks Tom, I have the prototype working with the aqara sensor

You just need to ground the 1v signal line to trigger a closed signal

Your thread triggered the idea, much appreciated, just trying to keep sensors on zigbee

[steady sapphire]

@wary solstice hey just checking in to say thank you for that fishing line tip, it worked marvellously for the phone proximity sensor / hanging card setup, it is now smooth as butter. And as an added bonus I used it for my switchbot setup as well, to have just one bot move both sides of the curtain via wire

for anyone with double sided curtains wanting to get automated bots, just a quick tip:
you don't need 2 devices, just need a nail at the end of each side of the curtain track so as to wrap a wire around it. With the unit on the left curtain side, have one wire attached to the right side of the unit going to the right hand side, wrap around the nail (180*) and attach to the first link of the right curtain, while the other wire will be attatched to the left side of the unit and go to the left hand side, wrap around the nail and attach to the same link of the right curtain.
Best use fishing wire to do this, tried and tested, no worries for weight

[bleak wyvern]

I wanted a HA status board for a couple of rooms in my house that I could tell at a glance status of a few binary sensors (alarm set, kids home, home maintenance overdue, all doors closed). I put together a simple board with individually controllable neo-pixels. I'm using ESPHOME and fastled partitions to toggle between green and red when there is a state change in one of the binary sensors. And just because I could, I threw in a I2C temperature sensor. I'm pretty happy with these and have one on each floor of the house.

[shy rapids]

That looks good, I'm assuming a neat 3D-printed case to go with it too? 🙂 Are you planning on releasing the board schematic and code for that, @bleak wyvern ?

[steady sapphire]

wow that's awesome, how's it work?

cool stuff

I also have a chair occupancy sensor but it's more loose, as it's only based on webcam and doods

been lookin for something to replace it so cheers 😄

[near eagle]

hi there. likely not nthe right place for this but iots the best one i could find. i'm trying to create a smart home heating system myself co i can set up better automations than retail ones would allow. i need a thermostatic radiator valve that would report to home assistant if it was calling for heat. also, if you know of a heating controller that allows me to just turn on the heat, that would also be helpful. i did some googling that proved to be unhelpful. jthanks!

Anybody knows what to do with broken esp32 wemos d1? I have no red light anymore. I read something to replace diode?

[south orchid]

i think i have a problem, using esp and trying to upload the code. After its done i can see it has connect to the right wifi. but in HA it just showing offline using a cabel to my mac if it makes any diffrent? bur after the install is done and showing the log i get this: """

[remote stream]

@fringe iron this all I got

Max output power 100w
Max output current 4a/ch
12v
5m strip

[fringe iron]

Ah, because imgur is too hard to post to...

MagicHome LED controller

I'd start by checking the connection between the controller and the strip, that's the most likely problem

[remote stream]

Ok thx

That is not the problem

I check and it is all ok the connection 😕

[fringe iron]

Then:

1. Test a known good strip with the controller
2. Test the controller with a known good strip
3. Test both with a known good connector cable

[remote stream]

This is my only led strip

I don't have others

[fringe iron]

Do you have a multi-meter?

[remote stream]

In what sense?

[fringe iron]

As in, do you own one?

(and do you know how to use it, if you do)

[remote stream]

No, I dont

[fringe iron]

Oh well, that'd have been one way to test for wire breaks

[remote stream]

Ah ok

I opened the controller

Is this all fine?

[tardy plover]

Nothing looks obviously broken. But that isn't saying much.

[remote stream]

Maybe if I describe the problem we can solve it:
The red light goes perfectly but the green one is very week and the blue doesn't work

[fringe iron]

Could be a fault in the controller,in the cable connecting the controller to the strip, or the strip

[surreal sparrow]

That could also be a bad power supply. Not enough voltage for the LEDs with higher forward voltage.

[crimson orchid]

This sounds like a potential powering issue. Red requires the lowest wattage to drive, then green, and blue is the highest. IIRC

[tardy plover]

Definitely, but bad power to the LEDs could still be a controller or cable issue as well...

[late salmon]

I need help setting up mosquito and a ESP8266

[pale vine]

Anyone built a media player with ESP32? I'm wondering if there are any recommendations on a pre-amp that can do volume control.

[hushed coral]

was looking for something like that myself now... would be great to have it self power, something like this maybe: https://mobiwater.co.ke/smarttanksensors/

wouldnt know where to start though. how would a device like that contact HA..? wifi and mqtt maybe?

[mystic shell]

I'd just use an esp8266 with tasmota hooked up to a temp gauge and a few wires at different levels in bit of pvc with an end cap and a small hole at the bottom, hanging from the lid of the skimmer box. The small hole is necessary so that the measured water level is accurate, and not picking up the sloshing.
Throw it in deep sleep, tell it to wake up once an hour to check the levels/temp, then go back to sleep. It'd hardly use any power so I'd just run it from a small rechargeable battery.

[glass fog]

Anyone know if there is anywhere on a Shelly dimmer 2 that I can get a ground and gpio 0 apart from on the header? Ive broken the header

[hushed coral]

you make it sound easy, but I still wouldn't know where to start..... would these be ready made components?

added to that, I would need a sensor that is in water all the time, alerting when water level drops so it is dry (and not like a dry sensor, alerting when it senses water). So it would be immersed 100% continuously, and have the correct IP classification for that. 67 probably or maybe even 68? not sure about that

[mystic shell]

Something like this for the water sensor.
https://a.aliexpress.com/_m0wqbk2

Only the wires are in the water, you can keep the rest up out of the water in a small box. Seal it where the wires come out with silicone or even hot glue.

Probably easiest to control with a wemos d1 mini - note this is 3.3v not 5v, so you'll have to use a voltage divider (basically just 2 resistors) so that you don't burn out the board.

If you're not in a huge rush, I'll be working on this myself later in the year, I can help you put it all together

[hushed coral]

Fyi: I have 2 large vertical tubes in my Pond (we call it swamp section) where the water if filtered . The pumps are at the bottom . The tubes are sealed with a lid. I figured the small box containing all is fixed to that lid, with a tiny whole for the sensor probe to go inside the tube.

It might even be made more simple, by just letting the probe rest in the swamp section. If water level decreases that runs dry soon before the pump runs dry ( it’s more that 150cm@deeper…) . All I am saying is, it doesn’t even need to be connected to the tubes at all..

Just a water sensor not sensing water ;/)

[proper magnet]

Completed my version of the FSR bed presence sensor today, now to see how well it works.

[ember quartz]

Is anyone using pca9685 with esp32?
Is it still functional with the latest updates?

[ember quartz]

As an alternative what would do you use to control an RGBW ledstrip? The cheapest way if possible. I was looking at ZigBee pwm devices but they're a bit more costly (£45) whereas esp is around £8

[lilac shadow]

Shelly RGBW2?

[ember quartz]

Not bad, do you have experience with it?

[lilac shadow]

no, but I have used other shelly devices

the 1 and 1pm

[ember quartz]

Thanks for the tip. Still 2x as much as would be with the esp32. But less expensive if I go for the esp and then it doesn't work and then having to buy a shelly 🤣

[lilac shadow]

but an esp isn't enough to drive LED strips on its own

[ember quartz]

I just need it to work with the pca 9685 to drive some FETs. I've had it working for a couple of years up until the latest update as python3.10 doesn't support the rpi_gpio_pwm library anymore

[ancient wedge]

Hey everyone, I've got an ESP32 running ESPresense and I've also got an HC-SR501 PIR sensor wired up to it. No matter what I set the sensitivity or time delay pots to, I get constant false positives. A friend of mine has the same hardware setup under ESPHome and is experiencing the same. I've tried setting the jumper to Repeat Trigger and Single Trigger.

Has anyone gotten either of these combinations to work w/o a crazy amount of false positives?

[thorn cairn]

I am not using this and I am also new to HA, but I am guessing, that the sensor sends trigger every time it detects person. And the trigger switches light on/off. I think there should be something done in your automation, maybe change a trigger type.
Maybe you should look on to templates, I think it has already one for presence light.

Hello everyone.
I am student and after experiences with domintell in our home I want to make project (for own use and also as final year project) for smart home.
I am thinking about touch display "switches" with programmable ui and buttons from web ui and also some manual switches (maybe some lights, relays, etc down the road). I was thinking about using zegbee/z-wave but it would make project expensive and also I didn't found lot of information about creating client. So I will probably use esp or rpi pico w with wifi. I also really like HomeAssistant so I want to use it as base.
Today I tried few experiments with MQTT. It worked ok, but it is limited and also hard to set up in HA (If you don't know what are you doing, you need to know all types of messages etc. I want to make it simple to use).
What do you think are my possible solutions? Create own addon and component? (I have experience creating an api and I think it would work in this example, but I am not sure how to implement it in HA and if it is the best solution). Or find a different protocol to comunicate with HA?
Please write your suggestions, I would be really happy.

something like these

That's not it @thorn cairn, it's not about an automation getting triggered, the entitity's history is showing activations when there isn't anyone in the room. This device is assembled and sitting on a shelf next my desk in my home office which has a closed door.

[thorn cairn]

oh okay, Sorry I can not help with that. I was just guessing

[ancient wedge]

This is likely a more low-level issue where someone more familiar with the specific hardware (HC-SR501) may have some feedback for me.

My initial assumption is that my habit of deciding which AliExpress listing to purchase based on which one is the cheapest is potentially the problem.

hey all, I have a question, I want to setup home assistant on a server and use raspberry pi's with sense hats as room sensors to detect temperature. Do you know where I can find a guide on how to do that...

[ancient wedge]

So the instance of HA will not be running on the RPi, correct?

[regal solstice]

correct. I just want it to report back to home assistant

[ancient wedge]

Seems like an expensive room sensor, is there a reason you want to go this route and not ESP8266?

[regal solstice]

I have 500 pi 3b+ with sense hats and I figured I could use some of them this with this

[ancient wedge]

lol...yeah, that might be considered a bit of a surplus.

[regal solstice]

LOL this company was going to trash them all and I said give them all to me!!!

[ancient wedge]

lucky you.

My first thought is that I would look into having the SensePis publish to MQTT

If you wanna send me a a dozen or so of them, I'll build it, document it and share it with you. 😉

Is there a plan to use the mic on the M5 Stack smart speakers with the voice assistant in HA?

[regal solstice]

how close are you to Ohio?

[ancient wedge]

Maybe ask in one of the devs channels?

[ancient wedge]

not very? West coast of Canada.

[regal solstice]

LOL WOW yeah that would be a drive..LOL

[ancient wedge]

While I appreciate the offer of white gloved delivery service, USPS would also be suitable.

(joke, obviously I'd be driving to you...in a world where you were much closer.)

[regal solstice]

LOL

[ancient wedge]

Are you already familiar with using MQTT?

[regal solstice]

so I am a beginner to Linux and raspberry pi's.. I saw home assistant and I was in love with it..

I never used MQTT

[ancient wedge]

Well, MQTT doesn't really require any Linux knowledge.

[regal solstice]

i only have dabbled with Home assistant one time

mqtt is all programming isn't it?

[ancient wedge]

MQTT is just a message broker, it's not really programming but understanding the concept of objects is useful.

A message broker is basically a high-performance database for transient data instead of long-term storage.

So you "publish" data to it like the temperature value of a sensor or lighting level then another thing subscribes to a topic, waiting for information to arrive, like an instance of HA which can then pull that data in as a "sensor".

But, if you've never done any programming, it could sound daunting I'm sure.

Have a read of that element14 link, it looks like you can get most of the way there with it.

[regal solstice]

element14 link? I would say no, because I haven't heard of that

[ancient wedge]

The one I posted up there ^

[regal solstice]

oh yes I am reading it currently

[regal solstice]

so i just want to make sure I have this correct...
Raspberry pi will gather all the data from the sense hat and then send it off to MQTT and then Home Assistant will pull that info from MQTT every X number of minutes......

Am I correct on that?

[untold wren]

Got my Emporia energy monitors flashed to esphome, setup in Home Assistant, and installed.

Not pictured is my rats nest of a breaker panel currently lol

[bleak cargo]

Dont know where to post this so I will post it here......
PRETEXT: If you are on the FB group I purchased these 4x4" Android 8 display switches that have 2 relays in them as GPIO's from Alibaba. The manufacturer gave me the API and I have posted a project on freelancer.com to make an android app that is MQTT-GPIO to run in the background of the Android Switch.

https://www.freelancer.com/projects/android/MQTT-GPIO-Android-34168530/details

I currently have a lovelace dashboard on the Android and need to gain access to the GPIO's hence why I posted the project on freelancer.com

QUESTION: How do i ensure that the APP that is designed, doesnt have any form of nefarious code in it that essentially has free access to parts of my infrastructure???

CLARIFICATION: Since posting on freelancer.com (Im not kidding when I say this was LESS THAN 15 minutes ago) some scammer (I dont quite know what the scam is) has cut and paste my project exactly TO THE WORD and 10 Indian/Bangladeshis' have bid on the scam project AND the bid pricing has been bidded upwards. Im going to leave the project up to expire regardless and NOT award the bid to anyone.

If anyone with integrity would like to give this a shot - pls let me know - I WAS willing to pay to get this done but with all the SCAM shit within minutes - now Im looking for someone with integrity
