Aeotec Multipurpose Sensor vs Nest Temperature Sensor

The Aeotec Multipurpose Sensor wins overall because it works on its own over Zigbee with SmartThings, Home Assistant, Google Home and Alexa, sends temperature alerts, and adds open/close and vibration sensing. The Nest Temperature Sensor is cheaper, better rated and longer-lasting on battery, but it only works as a Nest Thermostat accessory with no standalone features.

Independence and integrations. The Aeotec Multipurpose Sensor is a self-contained Zigbee sensor with alerts and multiple ecosystem integrations, while the Nest Temperature Sensor has no connectivity of its own and only feeds readings to a compatible Nest Thermostat via Google Home.

No. The Nest Temperature Sensor is purely a companion accessory for a compatible Nest Thermostat and has no independent Wi-Fi, Bluetooth, Zigbee or Z-Wave. The Aeotec Multipurpose Sensor works over standard Zigbee with any compatible hub.

No. Both measure temperature only. The Aeotec Multipurpose Sensor adds open/close and vibration detection, while the Nest Temperature Sensor adds nothing beyond feeding room temperature to a Nest Thermostat for scheduling.

SmartThings and Home Assistant users who want a standalone Zigbee sensor covering door/window contact, vibration and temperature with real alerts and automations. It is the more flexible pick for anyone building a hub-based smart home.

US-based owners of a compatible Nest Thermostat who want to fix a room that runs too hot or too cold. Its lower price and 2-year battery life make it an easy add-on, but it offers nothing outside the Nest ecosystem.
