Nest Temperature Sensor (2nd gen) vs Sonoff SNZB-02M AirGuard TH Pressure Sensor

The Sonoff SNZB-02M AirGuard TH Pressure Sensor wins as a general-purpose sensor, costing less, rating higher, carrying a longer warranty, and adding humidity, pressure and alerts. The Nest Temperature Sensor (2nd gen) only wins on battery life and only works as a Nest Thermostat accessory.

The Nest Temperature Sensor (2nd gen) has no independent connectivity and only feeds a paired Nest Thermostat, while the Sonoff SNZB-02M AirGuard TH Pressure Sensor is a standalone Zigbee sensor with its own humidity and atmospheric pressure readings.

The Nest Temperature Sensor (2nd gen), rated for about 3 years on a CR2 battery, versus about 2 years on the Sonoff SNZB-02M AirGuard TH Pressure Sensor's CR2477 cell.

No, it reads temperature only for its connected Nest Thermostat. The Sonoff SNZB-02M AirGuard TH Pressure Sensor measures temperature, humidity and atmospheric pressure.

Nest Thermostat owners who want a low-effort fix for one specific room that runs too hot or too cold, and value the longer battery life.

Anyone who wants a standalone Zigbee sensor for multi-room humidity and pressure monitoring rather than a single-brand thermostat accessory.
