Wiring diagram #3
Comments

Hi @tompointexe , i ll take time to make a sketch for the serial connection, but basically , if you re taking the quick and dirty way, without level shifters, you ll only need to wire tx to rx and rx to tx. |
|
Awesome Thanks |
|
Hello, Is it possible to have the connector wiring diagram ? Which color of the connector goes to VCC, GND, RX and TX ? Thanks in advance and congrats for your awesome work ! Sébastien |
|
@RaceX58 : i mseeking for it in my flying notes collection, and pictures , i ll post it here while found . |
|
@ouinouin |
|
couldnt find anything on my computer now that shows something 100% clear, the yellow is the 12V and the black is the GND apparently , (but im not confident that the colors of the wires doesnt change. @RaceX58 do you mind posting a picture of the connector so i can cross check while home? fot the TX and RX, you ll have to give a try (not dangerous). |
Did you say 12V ?? Shouldn't it be 5V? Yes no problem I'll take some pictures later today. |
|
Hi again, |
|
I'm looking at your code and it seems there's a little issue at line 364 StoreIfDifferent(TemperatureSetpointToACunit , TemperatureSetpointToACunit) Shouldn't the second parameter be a string ? |
|
@RaceX58 the Vin CANNOT be connected directly to the controller, on my unit its 12V , you have to place a small dc dc converter here the only pictures i have for now, not very informative , but can confirm on the small wires side, the red is +12V , blac is GND.
|
good catch , correcting it immediately. |
|
hey again. I'm almost good. I can get all the values from the AC but I have a problem with the TemperatureSetpoint. You can see it's initializing at 20 then it always returns nil. There are the logs. 00:00:00.002 HDW: ESP32-D0WDQ6 v1.0 |
|
I've found it. Had to replace persist.TemperatureSetpoint = TemperatureSetpoint by persist.TempSetpoint = TemperatureSetpoint |
|
@RaceX58 : thanks for correction, corrected and pushed it . feel free to open new issues for anything you find in the code (i m not a great coder, and i m half time veeeeery far from the unit so i tend to not touch this one so often in case i cant remotely recover a disaster :-) . |
|
@ouinouin I'll do. I'm a C# developper. I'm far to be a good C developper. Also the bytes and bits give me headaches... |
|
Also I'd like to implement the fan "mute" mode (Silence in french) |
Why would you like to connect it to tuya ?? and not HomeAssistant or another local smart home app, wich is the goal of this app |
|
My family have some Airton climate and I would like them to be able to control using a simple app. |
|
Haha fair enough, personaly i managed to get everyone to use homeassistant with simple dashboards ;) |
|
@RaceX58 i dont feel connecting to tuya is a good thing, this is really bad to let everybody enter our homes. For me , something nice would be to have a small webinterface over tasmota with all the controls. an intermediate thing can also be to interact with the excellent android opensource app http shortcuts. |
|
@ouinouin I get your point. Back to the code, can you tell me what means stepless ? I haven't tried it yet |
|
Stepless is a functionality of the fans apprently with the remote control you chan change the fan speed percent by percent. |
Okay that's not what I'm looking for. I'm looking for the mute option. I'm able to set on my official Wifi module using HomeAssistant but not using SmartLife. |
|
@RaceX58 i didnt see any control that can toggle off the buzzer, for me its hardwired to te main controller of the unit, the only volume control was sticking a screw in the buzzer |
I was not talking about the buzzer (I've removed it physically lol). I'm talking about the fan speed called "Silence" in french.
|
|
@RaceX58 its most likely the lowest possible speed , i dont know if its a special mode, or if its just the mode with the first bit to 1. |
|
@ouinouin I can't seem to be able to get the correct frame using an Arduino script. Here is an example (int values formatted with '-') 122-122-209-33-13-0-0-164-10-10-0-37-37-122-122-209-33-13-0-0-164-10-10-0-37-37-122-122-209-33-13-0-0-164-10-10-0-37-37- |
|
@RaceX58 maybe the framerate /stop bits ? , ca you convert your sequence to hex ( i m lazy to format your output) , to see if the frame looks like the same ? , but 122 is 7A in hex, so it looks like a framestart. the problem being how the library you are using ins behaving , when does it fills the buffer etc etc, i dont know enough about arduino, but sure you ll have to know what is the method of your library to fill its buffer and to signal you there is something in the buffer, since in serial the challenge is always to detect the start of a message . |
|
Be careful , i wiring TTL direct to the TX RX and after 10mn the RX TX stop to work.. next update lever shifter for communication. |
Hi, finaly took time to get back into this
Do you have a basic wiring diagram ? or is it as simple as plugging tx in rx and rx in tx ? i plan to use an ESP8266 or ESP32 if needed
Thanks :)
