I’ve just released the firmware for an ESP32-C6 to support Zigbee for a Ventair Skyfan DC. Hopefully of interest to people that have a Ventair Skyfan and want to automate it over Zigbee. Might also be useful to other enthusiasts interested in creating any ESP32-C6 based integration over Zigbee. Github repo includes general guide for building Zigbee controllers as well as info for integrating into zigbee2mqtt (including custom herdsman integrations).
