ComfoAir

Port of the ComfoAir protocol to ESPHome.io firmware, which is supported by external_components.

Add the following definition of external_components to your yaml configuration:

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

and then use it:

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