Sonoff SNZB-02M AirGuard TH Pressure Sensor vs X-Sense STH0B Smart Thermometer Hygrometer

Barometric pressure is the extra sensor that decides this comparison: the Sonoff SNZB-02M AirGuard TH Pressure Sensor wins over the X-Sense STH0B Smart Thermometer Hygrometer on battery life, integrations and sensor count. Beyond temperature and humidity, it adds pressure readings that the app turns into calculated dew point and vapour pressure deficit figures, and it reaches Google Home, Alexa, SmartThings and, through a SONOFF hub, Apple Home and Matter over Zigbee. The X-Sense STH0B Smart Thermometer Hygrometer answers with a lower price and a higher owner rating. Buyers who want dew point or VPD data for a greenhouse, cellar or workshop automation, and who already run a Zigbee hub, should choose the Sonoff SNZB-02M AirGuard TH Pressure Sensor; buyers who want the cheapest, most highly rated option and already own an X-Sense base station should pick the X-Sense STH0B Smart Thermometer Hygrometer instead.
