Aqara Climate Sensor W100 is a Zigbee temperature and humidity sensor with an LCD display and three programmable buttons, so it reads the room and doubles as a thermostat-style wall controller.
Works on integrations
Protocols
One mode at a time: the device serves one of these combinations, not all of them at once.
Setup guides
Roles it can fill
Combines an accurate temperature and humidity sensor, an LCD readout, and three programmable buttons, so it doubles as a thermostat-style wall controller. Runs over Zigbee (Aqara Hub) or as Matter over Thread, which needs a Thread border router on the network. Only one protocol can be active at a time.
