Nest Temperature Sensor vs Sonoff SNZB-02WD

The Sonoff SNZB-02WD wins overall, adding an LCD screen, IP65 weather resistance, humidity sensing, alerts and automations at a lower price. The Nest Temperature Sensor is a temperature-only Nest Thermostat accessory that nonetheless holds a higher owner rating.

The Sonoff is a self-contained Zigbee sensor with a display and weatherproofing that measures temperature and humidity and runs automations, while the Nest works only as an accessory to a Nest Thermostat and reads temperature alone with no screen.

The Sonoff SNZB-02WD does both, with a built-in LCD and an IP65 rating for garages, greenhouses and damp spots. The Nest Temperature Sensor has no screen and no weather-resistance rating.

Only the Sonoff SNZB-02WD, which senses both temperature and humidity and can send alerts on either. The Nest Temperature Sensor measures temperature only.

Zigbee smart-home users who want an on-device display, IP65 durability and humidity readings for outdoor or utility spaces, and who already run a Zigbee hub with Home Assistant.

Nest Thermostat owners who only need to help their thermostat balance the temperature of a specific room, and do not require a screen, humidity data, alerts or broader integrations.
