Aqara W100 Smart Climate Sensor

The Aqara W100 smart climate sensor measures temperature with an accuracy of ±0.2°C and humidity at ±2%RH, displayed in real-time on a 3.4-inch LCD screen. Featuring three programmable buttons, compatible with Matter over Thread and Zigbee 3.0, it seamlessly integrates with Apple Home, Google Home, Alexa, SmartThings, and Homey.

Real measurement accuracy, displayed in real-time

With a tolerance of ±0.2°C for temperature and ±2%RH for humidity, the Aqara W100 smart climate sensor provides reliable readings to maintain a comfortable environment, protect musical instruments, plants, or sensitive storage areas. In Zigbee mode, an additional Aqara temperature and humidity sensor can be paired to display data from a second location directly on the secondary area of the screen, without additional manipulation.

Three programmable buttons to control your home without a smartphone

The Aqara W100 smart climate sensor integrates three physical buttons configurable with up to nine distinct actions via single, double, or long presses. Dim the lights, activate a scene, turn on a fan, or trigger an automation directly from the sensor, without using the app. Immediate access to essential controls, placed on a desk or wall-mounted thanks to the included stand.

HVAC Control, Energy Savings, and Long Battery Life

Paired with the Aqara M3 hub, the Aqara W100 smart climate sensor controls compatible infrared air conditioners. Coupled with an Aqara thermostat, it manages central heating and ventilation via smart automations, for example, turning off the heating as soon as a window opens. The two included CR2450 batteries provide up to 2.4 years of battery life in Zigbee mode, with an adjustable reporting frequency to balance responsiveness and battery lifespan.

FAQ

Does the W100 work without an Aqara hub?

In Thread mode, the W100 connects directly to compatible Matter ecosystems without a dedicated Aqara hub, provided you have a Thread border router. In Zigbee mode, an Aqara gateway is required to access advanced features like external sensor display or HVAC control.

Can two different rooms be monitored from a single W100?

Yes, in Zigbee mode, an additional Aqara temperature and humidity sensor can be paired with the W100. Its readings appear in the secondary area of the screen, allowing two locations to be monitored simultaneously from a single device.

Are the W100's buttons customizable after installation?

Yes, the three buttons can be configured from the Aqara Home app. Each button supports three types of press (single, double, long), for a total of nine programmable actions, which can be modified at any time according to your needs.
