I've notices that i was trying to connect the M5Stack to the wrong connector! |

Pink +12V, white 0V. F1, F2 are under the metal cap. Let me know if you managed to establish communication with the unit. I can't handle it. I always have: [22:45:39][W][samsung_ac:080]: write 32d0c8d1d2000000000000001b34 |

Thank you for your message. Do you know if there is a connection diagram for this esphome_samsung_ac? |

do you have M5STACK ATOM Lite + M5STACK ATOM RS-485 Base? |

Was not able to find the base, but got this that is supposed to be similar in every way. |

Yay! Thank you! But can you share a picture of the location of V1, V2, F1 and F2 on the AC? |

I did it!!! I have one outdoor unit and 5 indoor ACs from 2015 (non-NASA). If you have any problems, write to me. |

Try my code. Change only GPIO.

Glad I could help you. Please check what works for you. I want to know if this is just my problem or all Non-NASA ACs |

I've just configured the desired temperature, actual temperature, fan speed and mode (warm or cold). In the future, if needed, i will try to add those things. Thank you again! |

Hello,
Following a suggestion from another user on the climate_ip integration, i've decided to try this one.
Got a few hours ago a M5Stack and a Tail485.
My ACs have the following WiFi module:
This is the internal connection:
This is the wiring diagram:
I've measured 12V on pin 5 (+) and pin 4 (-):
So, with this configuration, i think i can replace my wifi module with esphome_samsung_ac module, connection 12V and G.
Now i need to figure our if H_UART_SIN should be connected to A or B on the RS485 module.
Looking into the diagram on the Tail485 component i see that TXD has the same color as the A. This means that I should connect the A to pin 2?
I'm not sure if this will be compatible and if possible would like some guidance if i'm thinking correctly.
Thank you!
