1 year ago Hello I have the same AC samsung AR12TXHQASINEU , but for me it is impossible for the esphome midea component to work Could you send me how you did it to make it work for you, and with which board? And if possible, any photos of how it looks thank you very much

I made this quick prototype and its running for a year almost.
As of yaml, i can't access it currently. I followed basic configuration tutorial and it worked.
Only issue I'm currently having is that it's not recognized on first power on after power loss. There is no wifi symbol on ac. (also web server on esphome does not work). Manually power cycling the ac does the trick. I still gotta debug that.
I can try to find yaml and schematic of the board somewhere (due to some of my laziness my home assistant(including esphome) is offline for past 7 months)
How did you wire it up? Did you use level shifters? Serial on AC is at 5V. I accessed it on CN3. Also i hard wired IR receiver signal because it's not broken out at CN3. Look at the photos on Instagram for CN3

1 year ago I use the ESP-01 and took the UART module to get access. This video shows the hardware and how to get access through the UART module.
These are the pictures of how I connected the ESP-01 to the unit:
Sorry for the bad quality, but you "get the picture" :-)

1 year ago @devmarxx @DjordjeMandic Thank you very much to both of you It seems easier to me the way @devmarxx devmarx has done it, @devmarxx Could you send me the code of the yaml that you put in it please? Didn't you need to put a voltage exchanger for the RX and TX?
And it works perfectly with Home Assistant? Could you put me a little video of how it works if possible I'm going to buy the components to make it Thanks a lot
devmarxx
commented
1 year ago I'm not using Homeassistant. I'm using the build in webserver, because I manage the unit with my own python control scripts over wifi with a Raspberry Pi. But without the webserver Homeassistant should work.
Here my yaml:
This is a specific configuration to communicate with my python scripts (they are too unique to my situation, I'm not going to share them), but it should work for you as a starting point.

gedas07
commented
1 year ago @devmarxx And on the plate where is the temperature turns on the wifi symbol? All the time? or only when starting the AC?
DjordjeMandic
commented
1 year ago @gedas07 Wifi symbol is on only when the display on the cover is on. If ac is off or display is off then wifi symbol is also off
gedas07
commented
1 year ago @DjordjeMandic ok , my wifi simbol is off all the time , but for the moment only i try with wemos d1 mini , but don't work. i don't have response from RX
I'll waiting the new components
devmarxx
commented
1 year ago The wifi symbol behaves exactly as described by @DjordjeMandic
gedas07
commented
1 year ago @devmarxx @DjordjeMandic Ok thanks again, that is, when connecting the ESP-01 to the AC, the Wi-Fi icon will be on whenever the AC is on, correct? Does something do in the AC apart from connecting the programmed ESP-01? How to touch a key in the command to activate the wifi or something?
devmarxx
commented
1 year ago I use "esptool" (python) to compile and (first) flash. After the first flash I update with the webfrontend.
DjordjeMandic
commented
1 year ago As soon as mideauart library(esphome in this case) starts communication on the serial lines ac will recognize it and turn on wifi symbol. Basically as soon as esp queries data from AC it will turn on wifi symbol. You don't have to do anything in order for wifi symbol to show up. If you just connect everything and power on if it's working it will turn on wifi symbol.

@DjordjeMandic thanks a lot , but i think this is too dificult for me , if the esp-01 don't works for me , i try this but uffffffffffff. :)

1 year ago @gedas07 esp-01 will work, everything is the same in terms of level shifters and etc (you just use esp-01 instead of esp32c3). As far as i remember ac communicates on 5V so one basic level shifter with mosfet is mandatory. IR is needed only for some controls as documented by the esphome component

1 year ago Sorry, you are right! Apart from the ESP8266 ESP-01, I use an Adapter Breakout Board with 3.3V to 5V shifter. That is just plug and play.

1 year ago @devmarxx one question , what is absenkung? that is one switch in your yaml?
devmarxx
commented
1 year ago Good to read that you got it all running :-)
"absenkung" (German. Translated "lowering") is a switch for my python scripts. My scripts lower the target temperature for heating at night automatically. In case I don't want that to happen I can toggle that switch.
Regards
Chris
Edit: "Auto Mode" is also a switch for my scripts.
The problem
Selecting
Ecoin climate presets does nothing. AC does not beep like it does on any command. After 1-2seconds preset in homeassistant changes to what it was before selectingEco. If it was onNoneafter selectingEcoit stays inEcopreset for 1-2seconds and returns toNone, ac does not beep. Same if it wasBoostorFreeze ProtectionorSleep. Autoconfig added it because ac reported it.Which version of ESPHome has the issue?
2022.11.5
What type of installation are you using?
Home Assistant Add-on
Which version of Home Assistant has the issue?
2022.11.5
What platform are you using?
