I'm using an ESP8266 NodeMCU V2 board with an nRF905 antenna to control a Zehnder ComfoFan S. Make sure to follow the PIN structure. See my actual utility-bridge.yaml file in my Home Assistant repository.
- The pairing didn't work for me after trying many forks. Disconnecting the CE (D2) PIN worked for me and suddenly the device started to work!
There are a bunch of known issues either related to the base program, the fork or my config. I'll keep them documented under the issues section.
