ComfoAir

Port of ComfoAir protocol to ESPHome.io firmware originally by @wichers modified by @nyxnyx to be installed as external_components.

Add to your yaml configuration the definition of external_components:

external_components:
  - source:
      type: git
      url: https://github.com/nyxnyx/esphome-comfoair
    components: [comfoair]

and than use it:

  id: uart_bus
  rx_pin: 3
  tx_pin: 1
  baud_rate: 9600
