The Inovelli Blue Series On/Off Switch (VZM30-SN) is a Zigbee 3.0 in-wall switch with a built-in humidity sensor, making it a strong fit for bathroom and laundry exhaust fans. It pairs locally over ZHA or Zigbee2MQTT and adds an RGB notification LED bar with multi-tap scene control.

Roles it can fill
On/off only (not a dimmer) and requires a neutral wire. The onboard humidity sensor can trigger an exhaust fan automatically when a shower raises the moisture level. Control is fully local, and as a mains-powered Zigbee device it repeats the mesh for nearby battery sensors.
