Hi Adrian, not sure if this project is maintained still. I am using homebridge for a few years already and I recently found your great project for the ITHO vent, which I use also. I have the ESP8266 running & geared up. This homebridge plugin does not load and stops homebridge during start up cycle.

Below you can find the output of "tail -f /var/log/homebridge.err".
(Note I did not yet pair the running with the ITHO)

Thnx & kind regards, Ton
