Aqara Temperature and Humidity Sensor vs Nest Temperature Sensor

The Aqara Temperature and Humidity Sensor wins overall. It measures humidity and pressure, costs less, works standalone with HomeKit, Google Home, Alexa, Home Assistant, IFTTT and Matter, and sends temperature and humidity alerts. The Nest Temperature Sensor is better rated but only works as a Nest Thermostat accessory and reads temperature alone.

Independence and sensing. The Aqara is a self-contained temperature, humidity and pressure sensor with broad integrations, while the Nest Temperature Sensor has no connectivity of its own and only feeds room temperature to a compatible Nest Thermostat via Google Home.

No. The Nest Temperature Sensor measures temperature only and works only through a Nest Thermostat. The Aqara Temperature and Humidity Sensor measures temperature, humidity and atmospheric pressure and sends humidity alerts.

The Aqara, by a wide margin. It supports HomeKit, Google Home, Alexa, Home Assistant, IFTTT and Matter through a Zigbee hub. The Nest Temperature Sensor integrates only with Google Home, and only through a connected Nest Thermostat.

Buyers who want flexible, low-cost temperature and humidity monitoring across many rooms and platforms, including HomeKit, Home Assistant and Matter. It is the versatile default for climate tracking.

US-based owners of a compatible Nest Thermostat who just want to fix a room that runs too hot or too cold. It offers nothing outside the Nest ecosystem and does not measure humidity.
