2026 verdict
The SwitchBot Meter Plus is the stronger temperature and humidity sensor in this comparison, taking price, owner feedback, connectivity (Bluetooth plus Wi-Fi through a SwitchBot Hub) and its 3" LCD.
The Sonoff SNZB-02M AirGuard TH Pressure Sensor holds three rows of its own: a 2-year warranty against 1 year, a 2-year battery rating against 1 year and an atmospheric pressure sensor. The Meter Plus adds IP65 weather resistance, while the Sonoff is an indoor Zigbee sensor that needs a hub. Integrations tie, with Google Home, Alexa, SmartThings and Home Assistant on both and Matter through each brand's hub. For a sensor you read at a glance, the Meter Plus is the answer. For a hidden Zigbee sensor that logs pressure and runs longer between batteries, the Sonoff makes more sense.
