Aqara Climate Sensor W100

The Aqara Climate Sensor W100 brings comfort and control to your home. This smart sensor measures temperature (±0.2°C) and humidity (±2% RH) with pinpoint accuracy, displaying the current values directly on its large 3.4-inch LCD display. Thanks to Matter-over-Thread and Zigbee, the W100 connects directly to all major smart home platforms, including Apple Home, Google Home, Alexa, SmartThings, Home Assistant, and Homey. You can choose whether to use Thread or Zigbee, depending on your preference and existing network.

Unique to the W100 are its three smart buttons, allowing you to configure up to nine actions (single, double, or long presses). This allows you to easily control scenes or devices, such as lights, a fan, or your favorite mood setting, without having to reach for your phone. In Zigbee mode, you can even pair an additional Aqara temperature and humidity sensor, allowing you to monitor two rooms simultaneously on the display.

The W100 works seamlessly with Aqara thermostats (such as the Radiator Thermostat E1) and can even control your air conditioning (IR) via the Aqara Hub M3. This allows you to easily automate your climate control, for example, turning off the heating when a window is open. The sensor runs on two CR2450 batteries and has a lifespan of up to 2.4 years (Zigbee) or 2.3 years (Thread). You can adjust the reporting frequency for an optimal balance between updates and battery life.
