The Aqara W100 digital room thermostat measures temperature and humidity and displays real-time readings on its 3.4-inch LCD screen. It has three programmable physical buttons, each of which can trigger a different action with a single, double, or long press, for up to nine automations or scenes.

It supports Zigbee and Thread, as well as the Matter standard for connecting to smart home systems. Via an Aqara hub, it can connect to an Aqara thermostat or to a third-party infrared air conditioner through the Aqara Hub M3 for remote control. In Zigbee mode, it can also connect to an Aqara temperature and humidity sensor, allowing additional readings to appear in a secondary area of the display.
