Showcase Your setup and compatibility list

[vekexasia]

Hello, it would be nice if people share their setup and their comfo machine model number so I can keep track of the project compatibility list.

For now this is the known supported comfoair units:

• Comfoair Q350
• Comfoair Q450 - auto mode not available #52 (comment)

I made this work with my Q350, with a LilyGo TCAN-485.
I am a complete newb, but somehow managed anyway after some trial & error with a board that wasn't listed on this repo.
I thought it might help others.

I:

• wired the GND (black) from the Q350 to both CAN_GND and - for the board.
• wired 12V (red) to +.
• wired Yellow to CAN_H and white to CAN_L.

Added this to ESPHome yaml:

# For me, setting these to off made everything work.

  - platform: gpio
    id: can_se

  - platform: gpio
    id: can_en
    pin: 
      number: 16
      inverted: false
    name: "can_en"

I can confirm a working setup with a Q450:

I used these hardware components:
-AZ-Delivery LM2596S Buck DC-DC
-Waveshare SN65HVD230 Can
-AZDelivery NodeMCU ESP32 S (i used this one because it has an external antenna connection)
-external antenna

The configuration is not able to set "auto" mode. I added my insights in #52
