I'd like to pair weather station hardware (anamometer, etc) with meshtastic for cheap remote weather station. Here is something that might be hackable but it's $400 https://weatherxm.com/product/ws2000-helium-lorawan/

This is interesting https://community.weatherflow.com/t/project-tempest-into-helium-lorawan-network-just-started/20503

The Tempest Weather Community

Project Tempest into Helium LoraWan Network just started

just got a hurricane victim tempest station .and a idea…i like real accurate windsport knots,lorawan.mqtt,node-RED,SDR.rtl_433…and be a maker…

I swear sparkfun or someone used to sell weather station sensors

SparkFun Arduino IoT Weather Station

Whether you're an agriculturalist, a professional meteorologist, or a weather hobbyist, building a weather station can be a rewarding project.

#

Could use this and wire it up to a Meshtastic node

#

Or for $80 they sell just the sensors. You could integrate that into a custom setup where the mesh node hardware is monitoring the sensors

pulsar hornet Mar 17, 2024, 8:47 PM

#

Oh yeah nice find.

#

Oi. the anemometer uses a read switch. i wonder how long that would last : The anemometer (wind speed meter) encodes the wind speed by simply closing a switch which each rotation

foggy jasper Mar 17, 2024, 10:48 PM

#

i think its a magnetic one? so probably awhile tbh

mystic agate Apr 4, 2024, 2:30 PM

#

yes cool lets check this project together we can add the spot then in our App it`s free @ ios ,playstore

#

www.heliumsmartworld.com

#

we accept also DIY gateways with openmqtt_rtl_433 ,Lorawan Helium net , and i flashed also old android tv boxes with armbian installed rtl_433 github attached a sdr reciever and send the data to our mqtt 256 protocols😀

#

we are also in contact with weatherXm

#

and i plan to build this masterpiece anemo with a LTE ioT simcard connection

pulsar hornet Apr 4, 2024, 2:37 PM

#

Lora would be perfect to eliminate the extra cost of Sim/cell if you can get mesh network up

#

A lot less power requirement too

mystic agate Apr 4, 2024, 2:38 PM

#

just the interval are limited with lora we prefer 20-60 sec. updates

pulsar hornet Apr 4, 2024, 2:39 PM

#

Yeah, that interval sounds about right. With average calculations happening onboard

#

What are you testing exactly?

mystic agate Apr 4, 2024, 2:41 PM

#

everything we just finished the openmqtt rtl_433 integration into our App

#

www.heliumsmartworld.com

#

now we have almost all options just LTE ioT sim is missing

#

it would be cool to add some spots in MAUI

pulsar hornet Apr 4, 2024, 2:43 PM

#

Nice. I'd love to help.

#

I'll download app now

mystic agate Apr 4, 2024, 2:45 PM

#

right now our favorite stations are Ecowitt ws80,ws90,and ws68 this station we can easy integrate with the custom host option from the ecowitt gateways

#

and now a DIY solution with openmqtt rtl_433 board serial connected to a Meshtastic node to node and then mqtt solution would be also great

pulsar hornet Apr 4, 2024, 2:48 PM

#

Ultrasonic for$200, that's pretty good

#

I have an old tempest solar station but it's pretty closed, hard to hack

mystic agate Apr 4, 2024, 2:50 PM

#

uhhh tempest we had so much trouble with this hardware the old generation was fine but the new hardware always failed

#

Ecowitt is much cooler and cheaper

pulsar hornet Apr 4, 2024, 2:51 PM

#

UGG yeah. Can you get at the sensor data via serial without the WiFi hub involved?

mystic agate Apr 4, 2024, 2:52 PM

#

do you know openmqtt project rtl-433?

pulsar hornet Apr 4, 2024, 2:52 PM

#

Not particularly but I'm well versed in mqtt

mystic agate Apr 4, 2024, 2:53 PM

#

https://docs.openmqttgateway.com/

OpenMQTTGateway v1.7.0

One gateway, many technologies: MQTT gateway for ESP8266, ESP32, Sonoff RF Bridge or Arduino with bidirectional 433mhz/315mhz/868mhz, Infrared communications, BLE, beacons detection, mi flora / mi jia / LYWSD02/ Mi Scale compatibility, SMS & LORA.

#

you can get any cheap anemometer data send it to mqtt

#

same board like meshtastic use the web flash function

#

ecowitt ws 80

pulsar hornet Apr 4, 2024, 2:57 PM

#

I've got a meshtastic repeater at 8000ft here in Maui. Easy reach from kite Beach over LoRa

mystic agate Apr 4, 2024, 2:57 PM

#

from this board serial to meshtastic i guess it easy to cover 1-2 kilometers or more

#

in short intervals

pulsar hornet Apr 4, 2024, 2:58 PM

#

Getting 20km+ over Repeater

#

But I'll order one of those ecowitts to hack on.

#

Wow be nice to get meshtastic talking directly to the ecowitt over serial.

mystic agate Apr 4, 2024, 3:01 PM

#

yes as simple as possible of corse

pulsar hornet Apr 4, 2024, 3:02 PM

#

Any idea what the power draw is on the ecowitt?

mystic agate Apr 4, 2024, 3:03 PM

#

im testing right diferent station lacross bresser and ecowitt over rtl_433

pulsar hornet Apr 4, 2024, 3:04 PM

#

The ecowitt looks similar to tempest in that Lora to the WiFi gateway?

#

Running serial from station to rtl board?

#

About to takeoff. Talk later. Nice meeting ya.

#

on what spot you measure live wind in Maui? can you send me the location i`ll try to add the spot @mystic agate

pulsar hornet Apr 4, 2024, 3:30 PM

#

We use the iKite/wind alert paid sensor. I scrape it and put it here wildc.net/wind.txt

pulsar hornet Apr 4, 2024, 4:08 PM

#

i'm surprised nobody has even mentioned the tempest in project issues for rtl_433

pulsar hornet Apr 4, 2024, 4:26 PM

#

oh just saw your dead end thread on the google group.

mystic agate Apr 4, 2024, 7:42 PM

#

i started once save some signals from tempest for rtl-433 but then so many station broke down stoped working no remote reset etc i gave up on tempest

#

i use the solar panels etc.....

#

also the battery cant be easy changed at tempest thats really bad.. so much better on Ecowitt get a ws80 wind sensors are exactly the same like on the ws90

#

129 usd

#

and you have live knots in a 4,8 sec. interval

#

even this 80 usd setup works fine in a 16 sec interval

mystic agate Apr 4, 2024, 8:06 PM

#

pulsar hornet We use the iKite/wind alert paid sensor. I scrape it and put it here wildc.net/...

can you send me a map link where the station is located? the link is not working or the station id?

pulsar hornet Apr 4, 2024, 8:41 PM

#

Where is that data coming from? It's not accurate at the moment.

#

Should say 25kts avg

mystic agate Apr 4, 2024, 8:43 PM

#

Tempest🤪🤪

#

ill check 25 knots

pulsar hornet Apr 4, 2024, 8:45 PM

#

Ah, somebody's home station in their backyard probably

mystic agate Apr 4, 2024, 8:52 PM

#

i found this 3 sources there

#

i added ohter data more to 25 knots

pulsar hornet Apr 4, 2024, 9:58 PM

#

Which map are you searching?

mystic agate Apr 4, 2024, 11:56 PM

#

its in the app under search bottom corner right

pulsar hornet Apr 5, 2024, 12:37 AM

#

So the rtl_433 lets you pull data from the sensor without the wifi gateway right ?

#

and how is that ws68 ? looks like the cheapest available.

mystic agate Apr 5, 2024, 9:59 AM

#

pulsar hornet So the rtl_433 lets you pull data from the sensor without the wifi gateway right...

yes

mystic agate Apr 5, 2024, 10:01 AM

#

pulsar hornet and how is that ws68 ? looks like the cheapest available.

so far im happy with the datas

pulsar hornet Apr 5, 2024, 8:09 PM

#

How far away is your rtl443 Rx on that station?

mystic agate Apr 6, 2024, 1:14 PM

#

rtl_433 board i just started with the mqtt integration. The WS68 trnasmit the data to standart Ecowitt GW1100 gateway / distance station -gateway about 100 meters

#

im on it now with the openmqtt community to define a serail output interface on the rtl_433 boards . The idea is connect a openmqtt rtl_433 serial to a Meshtsastic node and transport the data over Meshtastic Repeater and the last Mesht. node sends the data to MQTT.

pulsar hornet Apr 6, 2024, 3:16 PM

#

That would be perfect.

mystic agate Apr 7, 2024, 2:11 PM

#

from the openmqtt board i get the wind data on serial

pulsar hornet Apr 7, 2024, 4:00 PM

#

Are there any serial pins on the ecowitt board?

pulsar hornet Apr 7, 2024, 4:47 PM

#

@mystic agate I don't see a fault 11 anywhere

mystic agate Apr 7, 2024, 7:04 PM

#

got it now from ttgo openmqtt rtl433 to a ttgo meshtastic transfer to a rak4631 meshtastic node

mystic agate Apr 8, 2024, 5:26 PM

#

TTGO -Heltec Board serial works also fine 👍. so is just the RAK boards mission

#

and the critical fault 11 .... but i`ts maybe to much data or buffer

#

ill ask the openmqtt guys if they could do a data serial output with logging configuration this would be a easy way to transfer datas over serial.

pulsar hornet Apr 9, 2024, 12:19 AM

#

@mystic agate I wonder if this issue is because softserial on nrf might not work?

pulsar hornet Apr 9, 2024, 2:15 AM

#

well #11 is not very descriptive : /* A (likely software but possibly hardware) failure was detected while trying to send packets. If this occurs on your board, please post in the forum so that we can ask you to collect some information to allow fixing this bug */ meshtastic_CriticalErrorCode_RADIO_SPI_BUG = 11

#

see if you can capture serial output when this happens. @mystic agate

pulsar hornet Apr 9, 2024, 10:56 PM

#

This is the only the place in the code where that error is generated so it's something to do with the communication with the LoRa chip

/** start an immediate transmit */
void RadioLibInterface::startSend(meshtastic_MeshPacket *txp)
{
    printPacket("Starting low level send", txp);
    if (disabled || !config.lora.tx_enabled) {
        LOG_WARN("startSend is dropping tx packet because we are disabled\n");
        packetPool.release(txp);
    } else {
        configHardwareForSend(); // must be after setStandby

        size_t numbytes = beginSending(txp);

        int res = iface->startTransmit(radiobuf, numbytes);
        if (res != RADIOLIB_ERR_NONE) {
            LOG_ERROR("startTransmit failed, error=%d\n", res);
            RECORD_CRITICALERROR(meshtastic_CriticalErrorCode_RADIO_SPI_BUG);

            // This send failed, but make sure to 'complete' it properly
            completeSending();
            startReceive(); // Restart receive mode (because startTransmit failed ```

pulsar hornet Apr 10, 2024, 3:47 PM

#

@mystic agateWhat's the circuit board inside the ecowitt units looks like ? any obvious serial port pads ?

mystic agate Apr 10, 2024, 6:46 PM

#

i didnt open it but on the Ecowitt gateways you have the option custom host....

#

ecowitt you dont need to hack it`s a very user friendly system

#

one thing maybe a openmqtt board as receiver and then send the data to the helium /crankk or TTN net that would be a Ecowitt Lorawan for some use cases

#

guess that would be easy

Here is the translation from the german pdf image To activate full data output via UART, the pulldown resistor R4 is removed and a 10k Ohm pullup is installed instead. The 3.3V can be taken from C31 using a cable bridge, for example. The data output takes place via TP6. We solder this to pin 6 of U2 (probably RS485 preparation), which is connected to a free line in the lower half of the sensor. We can later connect the data line to the outside there.

#

#

that's pretty slick if I say so myself.

mystic agate Apr 16, 2024, 7:04 PM

#

yes but a nice pcb

#

do you know ???on the tempest this contact are for external power but... is there maybe also uart in this contacts?

pulsar hornet Apr 16, 2024, 9:31 PM

@mystic agate interesting idea. I'll check with the scope and see if there is any signal

mystic agate Apr 16, 2024, 11:36 PM

tempest is nice they write uart rx tx on the pcb😀

#

tempest new version hardware 😀 also rx tx

pulsar hornet Apr 17, 2024, 12:48 AM

#

I have an extra older version. Maybe I'll try hack in a meshtastic transmitter.

#

I didn't even see those even I opened it up before.

#

We should decide on a compact data format for transmitting wind data.

mystic agate Apr 17, 2024, 1:27 AM

#

the top one is the old hardware version and the lower the new one

#

the old hardware is better.. i have 3 new gen. stations here they all failed after 3 days measuring and tempest replaced it but i`m done tempest to much troubles with this stations

pulsar hornet Apr 17, 2024, 3:24 AM

i only have an old tempest and the power connection are only + and -

I think it might spit out data once it's setup and bound to a base station. Hopefully it will still spit out data even if base station is off once setup.

Not much luck on serial output or trying to enable debug mode or give it commands. I can initiate tests from the serial port though.

Rak powered by the ws80 and reading serial data and sending avg info to mesh

pulsar hornet May 10, 2024, 9:11 PM

Translated from German : Now comes the most difficult part: the lower half is glued with silicone. First remove the 4 screws. To open it, slowly and carefully cut it around with a cutter knife and when you get something into the slot with the knife, carefully pry it open all around. With a little patience and sensitivity, the case can be opened without leaving any traces.

[Picture follows]

If the lower part is open, you can carefully tighten the cables in the stilts from above so that you gain more freedom of movement. If these pinch, help with a little silicone spray and make sure that the cables are in a good position when entering the stilt.

[Picture follows]

Now the three screws on the lower circuit board are removed and the contacts from the battery compartment and supercapacitor are unsoldered and the circuit board is removed. The heater cable can be cut off close to the circuit board, cut the second cable of approximately the same length and simply pull out the old cable. The thermal switch is no longer used and can be removed to free up space

I wish I could find someone to help me bodge the code to read analog sensors from this module: https://store.rakwireless.com/products/rak5811-0-5v-analog-interface

RAKwireless Store

0-5V Interface Module STMicroelectronics LM2902 | RAK5811

As an extension to the LoRaWAN®-enabled WisBlock system to provide analog input ports, the RAK5811 WisBlock 0-5V Interface Module is ideal for solutions that use analog signal.

#

I am totally lost whn I look at the meshtastic firmware, looks totally different then the simple arduino sketches I am used to working with 🙂

#

All I would need is to read the 2 analog inputs from this module, and send to the mesh at a set interval

pulsar hornet May 12, 2024, 12:14 AM

#

@dense flaxyes the code base is rather complex. my bodgement in the serial module should work for you too. instead of reading the serial data during it's runonce method calls you could read the analog values and send to the mesh.

dense flax May 12, 2024, 12:16 AM

#

Ok, would you be able to help me find the correct spot to do this, I am a total noob when it comes to coding....

pulsar hornet May 12, 2024, 12:16 AM

#

are you really measuring analog values up to 5v ?

dense flax May 12, 2024, 12:17 AM

#

pulsar hornet are you really measuring analog values up to 5v ?

Yes, this module( RAK5811) has a 12 volt output to power a 12 volt pressure sensor (industrial) which will output a 0-5 volt signal based on the pressure it is sensing....

pulsar hornet May 12, 2024, 12:18 AM

#

ah ok.

#

yeah shouldn't be too hard. what interval do you want to measure ?

#

the entire example loop for that board is just this ```arduino
void loop()
{
int i;
int mcu_ain_raw = 0;
int average_raw;
float mcu_ain_voltage;
float voltage_sensor; // variable to store the value coming from the sensor

for (i = 0; i < NO_OF_SAMPLES; i++)
{
    mcu_ain_raw += analogRead(WB_A1);                // the input pin A1 for the potentiometer
}
average_raw = mcu_ain_raw / i;

mcu_ain_voltage = average_raw * 3.0 / 1024;     //raef 3.0V / 10bit ADC

voltage_sensor = mcu_ain_voltage / 0.6;         //WisBlock RAK5811 (0 ~ 5V).   Input signal reduced to 6/10 and output

Serial.printf("-------average_value------ = %d\n", average_raw);
Serial.printf("-------voltage_sensor------ = %f\n", voltage_sensor);

delay(2000);

}```

pulsar hornet Jun 24, 2024, 5:51 AM

#

Regarding this station (ws80 and ws85) and possibly having working i2c : if this is not the case and serial is the only way to get data out if this thing, what's the best way to make meshtastic talk to this thing as a telemetry sensor ? I've got working code all bodged into the SerialModule but it just sends out a text message string with the wind data. I think it would bee really cool to enable this device as a telemetry sensor. It spits out a data about ever second but only useable data about every 5 seconds.

trail needle Jun 24, 2024, 11:12 AM

#

IMO we can create a special serial mode for this hardware that parses and pipes it to Environmental Telemetry

trail needle Jun 24, 2024, 12:07 PM

#

I can request to pick one up in the budget and try to help get it into the main firmware

#

Is the WS85 the one to get?

pulsar hornet Jun 24, 2024, 9:45 PM

#

yeah the ws85 is the the most available and easy to modify for serial output. I could do the mod and send you the hardware if you don't feel like soldering stuff. This is what the mod looks like :

Screenshot_2024-06-24_at_11.44.37_AM.png

#

I could also send you a dump of what the serial output looks like.

#

But before we do that I'll probe those i2c pins to make sure we don't need serial.

what are your thoughts on the lark station?

pulsar hornet Jun 25, 2024, 8:26 AM

#

@ancient forgeit kinda works. I couldn't get it output serial but it did output i2c data. The problem with it is that it doesn't output the wind direction with very much precision, only N,S,E,W NW, NE, SE,SW. Most good anemometers will output wind direction in degrees. Overall it's a very flakey system and I wouldn't expect it to continue running if deployed permanently.

For WS85 i'm currently logging direction AVGgGUST cellVoltage supercap voltage like so : INFO | ??:??:?? 55 [SerialModule] WS85 : 30 0.0g0.0 2.4v 5.2v

#

Sending this out as text message as well. I'm going to embed the chopped down rak in the WS85 and monitor the voltages, see what happens. Last time I connected the battery terminals of the RAK to the 3.3v rail on the WS80 board and it didn't last through the night. I'm not sure if that's just super inneficient or what. The supercap charges up to 5.4V during the day from the solar panel. I assume it could handle a little extra current for the RAK but we'll see.

Is the anemometer supported in Meshtastic firmware?

pulsar hornet Jun 27, 2024, 9:15 PM

#

@weak basinnot officially. I have it working with my own hacked SerialModule though.

weak basin Jun 27, 2024, 9:16 PM

#

So a arduino hooked up to a node?

pulsar hornet Jun 27, 2024, 9:17 PM

#

It's not an arduino but some custom chip with serial output.

#

#

I tried powering the RAK directly off the WX 3.3v rail but the super cap didn't last even an hour sooo.

#

The supercap voltage is that last voltage reading.

#

And now in the sun the supercap charges up in less than an hour.

#

BAT32G157 microcontroller

#

it output a mess of serial data that needs to be parsed and averages calculated which happens in custom code in the serialmodule.

weak basin Jun 27, 2024, 9:21 PM

#

Is there work done for supporting anemometer in software?

pulsar hornet Jun 27, 2024, 9:24 PM

#

not sure what you mean. thebentern did some work to support an i2c sensor called LARK

#

9.44mAh is apparently what's available from the supercaps.

#

I was measuring what that rak was using and it was about 10ma so no wonder it only lasted an hour.

#

I guess I'll just stick with external rak device with it's own solar.
