I succeeded to control my Zehnder ComfoFan S by using a DOIT ESP32 Devkit V1 and a nrf905. I’ve implemented this project on the ESP32 with Arduino: [https://github.com/eelcohn/nRF905-API](https://github.com/eelcohn/nRF905-API).

See my project on: [https://gathering.tweakers.net/forum/list\_message/63938230#63938230](https://gathering.tweakers.net/forum/list_message/63938230#63938230)

Now I’m able to control the unit using all kind of sensors.

It works like a charm.

I just used a Qubino 0-10V module for this. I was just plugging in and using it 😀

Hi Ruud,

Very good and simple solution. But it’s a very expensive solution (€50,00). I solved this automation issue for just €5,00 and I didn’t need to open the unit. 😀
