Aeotec Multipurpose Sensor vs Aqara Temperature and Humidity Sensor

For monitoring temperature and humidity, the Aqara Temperature and Humidity Sensor wins overall. It actually measures humidity and atmospheric pressure (the Aeotec measures temperature only), lasts about 2 years per battery versus roughly 1 year and costs less. The Aqara Temperature and Humidity Sensor also supports more platforms, adding Apple HomeKit, IFTTT and Matter through an Aqara hub. The Aeotec Multipurpose Sensor carries a higher owner rating and adds vibration and open/close detection, but it is a contact sensor first, not a dedicated climate sensor.

The core difference is what each one is built to do. The Aqara is a dedicated temperature, humidity and pressure monitor, while the Aeotec Multipurpose Sensor is a door/window contact sensor with vibration and tilt detection plus a basic temperature reading, and it does not sense humidity. If humidity tracking matters, only the Aqara covers it.

No. Despite sitting in the temperature and humidity category, the Aeotec Multipurpose Sensor only reports temperature alongside its main open/close and vibration sensing. The Aqara Temperature and Humidity Sensor measures temperature, humidity and atmospheric pressure.

Yes. Both are Zigbee devices that require a Zigbee hub or coordinator to work. The Aqara pairs with an Aqara hub or third-party Zigbee dongles and reaches HomeKit, Google Home, Alexa, Home Assistant and IFTTT, while the Aeotec works with SmartThings, Home Assistant, Google Home and Alexa but not HomeKit.

Buyers whose priority is climate monitoring: tracking room comfort, watching a damp bathroom, or catching a failing fridge or freezer. Its humidity and pressure sensing, longer battery life, low price and broad ecosystem support make it the natural default for multi-room temperature and humidity tracking.

Buyers whose priority is door, window and vibration monitoring on SmartThings or Home Assistant, with rough ambient temperature as a bonus. Its open/close, tilt and knock detection make it useful for entry doors and appliance-cycle alerts, but it is not the right pick if humidity readings are the main goal.
