I think this project is dead, as the owner hasn't replied or committed for a long time. Since you referenced ESPHome, you could take a look here for a newer ESPHome-based alternative to this project: https://github.com/Sanderhuisman/ESPHome-Zehnder-RF
thanks!
I bought a nodemcu and de nfr followed the steps but got errors and don't know how to resolve. What's wrong? What do I miss?
I see also a folder on this github: homeassistant. is that a option to flash it with esphome or something?::handleClient()':
