Both carry an IP65 rating for garages, greenhouses and outdoor spots, but the SwitchBot works standalone over Bluetooth and reaches Google Home, Alexa, SmartThings, Home Assistant, IFTTT and Matter through a SwitchBot Hub, a much wider set than the Sonoff's confirmed Home Assistant support. The Sonoff SNZB-02WD keeps two real advantages: a higher owner rating and a built-in LCD display that shows readings without an app, though it is Zigbee-only and needs a hub. Zigbee households that want an on-device screen should favor the Sonoff SNZB-02WD; buyers who want the broadest integrations, including Matter, and standalone Bluetooth use should choose the SwitchBot Indoor/Outdoor Thermo-Hygrometer.
