esp32- FCU (cooling& heating ) control and light control

[vocal ore]

i made 6 panel like this for smart system control FCU & light control for big company

[sharp mauve]

would like to see more

looking good

[quasi pecan]

@vocal ore another way to do this is connect the MCP23017 breakout board directly to 8ch relay board pins

[prime garden]

If you had one with pins on opposite sides like this you could even hook up both relay boards like in the box

[vocal ore]

many thanks no i dont have but i will buy it soon

[vocal ore]

no i don't have but will search about it in Aliexpress

and many thanx for you all best wishes for us

[prime garden]

You way works too! If you need to control more outputs though this might make it easier. PCF8575

[sharp mauve]

found this today

https://www.aliexpress.com/item/1005005883903139.html

it has chip on it already and connectors G VIN SDA SCL so you can just plug more directly trough it

[prime garden]

oh nice, and the A0/A1/A2 contacts so you can configure the address. you could hook 8 of those up to one I2C bus!

[vocal ore]

When I turn on the switches through ESP32 at once, some of them work while others do not, and then the ESP32 stops responding. What is the cause of this problem, and what is the solution?

[sharp mauve]

you mean when you turn on all relays at once?

does it reset?

[prime garden]

When you say "turn on the switches through ESP32", what do you mean? How are you turning them on specifically? Code/commands in your yaml? The web UI? Home assistant? Share your configuration/commands.

How are you powering the ESP? And the relay boards?

[vocal ore]

using homeassistat and yaml code this code :

sphome:
name: esp32_switch
platform: ESP32
board: esp32dev

wifi:
ssid: ""
password: "***"

Set a static IP address

manual_ip:
static_ip: 192.168.1.1
gateway: 200.62.50.52
subnet: 255.255.255.0
dns1: 8.8.8.8

api:
password: "gvsghsgfjndfsdt5ewytgerger344563ter"

logger:

Define all GPIO pins as switches

switch:

• platform: gpio

  pin: 4

  name: "GPIO 5 Switch"

To format your text as code, enter three backticks on the first line, press Enter for a new line, paste your code, press Enter again for another new line, and lastly three more backticks.
```yaml

Don't forget you can edit your post rather than repeatedly posting the same thing.

[verbal verge]

But that also didn't answer the question that was asked.

[vocal ore]

can you ask me agian ?

[vocal ore]

yes and when i turn on or off switches fast

[vocal ore]

have 2 source power one for esp32 (mobile charger ) and 12v power supply for relay module and connect GND with us

[verbal verge]

Can you watch the serial logs?

[prime garden]

You're turning them on and off fast through what? Home assistant? The web ui?

[vocal ore]

How are you turning them on specifically? using pc install virtual machine home assistant and install esphome in homeassistant then add device and chose esp32 and connect buy usb cable then connect then skip open esp32 device and write code then save and download Manual chose Modern Format then install factorty.bin file

[vocal ore]

yes or app mobile

[vocal ore]

yes i think well cheek tomorrow

[prime garden]

How many amps/watts does the mobile charger support?

And does the same issue happen if you program the esp and switch it fast, but not attached to the relays?

[vocal ore]

If between pressing the switch and the other a few seconds the problem does not happen

[prime garden]

I would connect your ESP's USB to your computer and run esphome logs your.yaml, then try switching fast and see if any error messages come up

[vocal ore]

I will share it with you now

[prime garden]

this happens without being attached to the relays?

[prime garden]

👆

[vocal ore]

yes this just connect esp32 with pc have home assistant virtual machine and open loges then turn on off and turn on quickly

then dawonlad loge in txt file

[verbal verge]

You need to get serial logs to find out what's happening.

[vocal ore]

where can find this serial logos ?

[verbal verge]

Plug the device into a computer and use either the web installer or a program like putty to watch the serial port.

[vocal ore]

Now it is important to keep OTA and API in the code or not ?

[prime garden]

not for the purposes of getting the logs, but it would be good to test with the same or most similar config to the ones you've been seeing issues with

[vocal ore]

i will tell you that i have 4 panel like this all work very good

i connect with home assistant 6 esp32 work good but and i will try change esp32 hardware to another one and cheek

Allow me to thank you for your effort and interest in solving my problem thank you from the bottom of my heart

[vocal ore]

?

[verbal verge]

?

[vocal ore]

hello

[fiery scarab]

Where did you get the board the esp32 is attached to - been looking for one just like that- Thanks

[vocal ore]

you mean the box ?

or shield under esp32

[prime garden]

probably means the shield, but sharing info for both might be helpful for others

[vocal ore]

yes bro

[vocal ore]

is you mean shield from aliexpress or amazon or you can made it by PCB design if you want PCB design for it i can made it for you

[fiery scarab]

Yes the shield - I bought similar from aliexpress a while ago but the spacing between the rows of pins was wrong for the esp32 devkitv1 board I use

[fiery scarab]

Do you mean you would share your PCB design 🙂

[vocal ore]

which esp32 you have

?

[fiery scarab]

esp32-wroom32 on esp32 devkit1 board which has two rows of 15 pins each

[vocal ore]

i will after finish it will share it her but am late beacuse not finished this potject

i want add lan8720 for every panel but have proplem connection betweet lan8720 with esphome any pne expret here

[verbal verge]

Do you mean a software or hardware problem?

[sharp mauve]

I think he needs pins 🤔

[vocal ore]

many thanx
i connect lan8720 with external power ESP32 connect with raspberry pi install esp32 on esphome i look for logs every thin is good and connected and show all information about connection ip mac addres duplex , link speed and ethernet connected then i go to setting add device add integration search for esphome and put ip and submit but notheing happend

[vocal ore]

just connect 3 pin and 2 for VCC and GND
mdc GPIO23
mdioGPIO18
clk_mode: GPIO0_IN
phy_addr: 1

[verbal verge]

"nothing" happened? You should get some message. Either it fails or it works.

Can you ping that IP address?

[vocal ore]

Yes, ping on the IP, it doesn't give that there is a connected device and there is no

[grand iron]

Can I Write on this thread or make a new one? I have one of them espwroom but a 16 relay board and new to all of this? 🙂

[verbal verge]

If you're wanting help with using it, create a thread in #general-support

[grand iron]

Fantastic I will do so 🙂
