ESPHome implementation of the CN105 protocol. It can operate as standalone or with slave (melcloud/procon) attached. It includes server control mode, realtime power output estimation and realtime daily energy counters.
The remote thermostat protocol CNRF is supported by https://github.com/gekkekoe/esphome-ecodan-remote-thermostat. It implements a virtual thermostat that can be linked with any temperature sensor.
