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.

From the zigbee2mqtt device database (zigbee-herdsman-converters
26.118.0):
the entities zigbee2mqtt creates for
VZM30-SN.
Paired through ZHA instead, the same hardware produces a different set.
Events and automation triggers
Presses on this device reach Home Assistant as device triggers through
the
Zigbee Home Automation
integration, which you pick in the automation editor after pairing.
The button list, and whether each button also becomes an
event
entity, comes from what the device reports at pairing time, so it
appears once the device is on the network.
Read from Home Assistant 2026.8.3: the integration declares these trigger types, and core holds no per-model button list for this device.

Movie Mode
Installs a Home Assistant automation that dims the lights when the TV starts playing and brings them back when it stops. Add shades to close, a soundbar to power on, a scene button to trigger it by hand, and dimmable accent lights.
Solar Surplus EV Charging
Installs a Home Assistant automation that starts your EV charger when your solar array is producing a surplus and stops it when production drops, so the car pulls from the roof rather than the grid. Add a grid meter and a home battery and it holds back until they are happy too.
