This project is inspired by the work of many others who successfully managed to replace the hardware bridge from Zehnder called “Comfoconnect LAN C” by an ESP32 + CAN transceiver, namely those ones in particular : GitHub - vekexasia/comfoair-esp32: Interact with Zehnder Comfoair with esp32 & GitHub - dardhal/comfoair-esp32
This new device is meant to not only replace the ComfoConnect LAN but also the ComfoSense controller display which is the default display typically installed in the house to interact with the ComfoAir. On top of having a much better UI, it’s been optimized to be very snappy and responsive and fully integrable into Home Assistant via MQTT.
It is a plug and play, cost effective solution since it’s leveraging off the shelf components from Waveshare.
This device can function in two modes: Directly connected to the ComfoAir, in place of the ComfoSense or as a Remote Client together with a MQTT bridge, with the same firmware
