After the discovery of the Aqara G2 camera with Zigbee bridge integrated and the Aqara LED Light Bulb smart bulb test, we continue today our exploration of the Aqara ecosystem with a very small sensor that should interest more than one Alexian. Indeed, many of us appreciate being able to monitor the temperature of their home from a mobile application or, even better, by querying Alexa. Unfortunately, the connected weather stations and compatible thermometers Alexa are still scarce, and it is difficult to obtain them at affordable prices. This is where Aqara comes in by offering us a solution that is both affordable and very compact: the Aqara Temperature Sensor!

a sensor that simultaneously acts as a thermometer, hygrometer and barometer. Operating in Zigbee thanks to a Aqara bridge or Mijia, its compactness and design will obviously only seduce you, which is why we are unveiling it to you today, shortly before the start of its marketing in France.

Aqara Temperature Sensor: a truly discreet temperature and humidity sensor

Please note that you will need to obtain a Zigbee Aqara footbridge - or Xiaomi Mijia - to make it work. Indeed, that of our Echo devices is not compatible, but the arrival in France of the Aqara Europe gateway is imminent, you will soon be able to get it. Note, moreover, that it is strongly advised to wait a few weeks rather than acquiring a Chinese model.

Equipped with a humidifier allowing it to calibrate itself, it operates in fact thanks to a single CR2032 battery capable of powering it for 2 years, the Zigbee requires very little energy to operate, unlike Wi-Fi.

Another strength of the Xiaomi ecosystem and the Mi Home application: the interoperability of devices from different brands and the possibilities of automation.
