2026 verdict
The SwitchBot Indoor/Outdoor Thermo-Hygrometer edges this one out as a temperature and humidity sensor, winning on price and integrations, notably adding SmartThings and Matter support plus an IP65 weather-resistance rating for outdoor and damp placements. Both sensors track temperature and humidity with alerts, automations and history, but the SwitchBot runs standalone over Bluetooth while the Sonoff SNZB-02P Temperature & Humidity Sensor is Zigbee-only. The Sonoff answers with a higher owner rating and a longer battery life, roughly four years on its CR2477 cell against about two years on the SwitchBot's AAA cells, and slots cleanly into Zigbee setups like Home Assistant and Zigbee2MQTT. Zigbee-first households wanting maximum battery life should lean to the Sonoff SNZB-02P Temperature & Humidity Sensor; buyers who want a weatherproof, Bluetooth-based sensor with Matter and SmartThings should take the SwitchBot Indoor/Outdoor Thermo-Hygrometer.
