2026 verdict
For a garage, greenhouse or log store where the sensor gets wet or dusty, the Sonoff SNZB-02WD is the better Zigbee temperature sensor of these two: an IP65 body with a built-in LCD that shows the reading without opening an app.
The Aqara Temperature and Humidity Sensor answers with atmospheric pressure, a small body and broad platform reach through an Aqara hub, but it has no screen and no weather resistance. Both need a Zigbee hub and both work with Home Assistant. Pick the Sonoff SNZB-02WD for outdoor, damp or glance-and-go spots, and the Aqara Temperature and Humidity Sensor for tucking inside a fridge, a cabinet or a HomeKit setup.

What the differences mean
Weather resistance
The Sonoff SNZB-02WD is rated IP65, so damp garages, greenhouses and outdoor spots are within its design. The Aqara Temperature and Humidity Sensor has no weather resistance and is meant for indoors or covered places.
On-device display
The Sonoff SNZB-02WD has an LCD, so anyone walking past reads the temperature and humidity. The Aqara Temperature and Humidity Sensor has no screen; the reading only appears in an app or dashboard.
Atmospheric pressure
The Aqara Temperature and Humidity Sensor also reports atmospheric pressure. The Sonoff SNZB-02WD reads temperature and humidity only.
Size and battery
The Aqara Temperature and Humidity Sensor is a 36 x 36 x 9 mm, 13 g puck on a CR2032 rated for 2 years, small enough for a shelf in the fridge. The catalog does not document the dimensions or battery life of the Sonoff SNZB-02WD, so check its size before planning a tight spot.
Apple Home and Matter
Both reach Apple Home and Matter only through their own maker's hub: an Aqara hub for the Aqara Temperature and Humidity Sensor and a SONOFF hub for the Sonoff SNZB-02WD.
Which one to buy if
- the sensor lives in a garage, a greenhouse or outdoors
The Sonoff SNZB-02WD has an IP65 rating, which the Aqara Temperature and Humidity Sensor lacks.
- you want to read the temperature without pulling out your phone
The Sonoff SNZB-02WD shows its readings on a built-in LCD.
- you already run an Aqara hub for HomeKit
The Aqara Temperature and Humidity Sensor pairs with it directly and reaches Apple Home and Matter through that hub.
- you need a sensor small enough for a fridge shelf
The Aqara Temperature and Humidity Sensor measures 36 x 36 x 9 mm and weighs 13 g.

What owners say
Owners of both sensors describe simple pairing with Home Assistant, through ZHA or Zigbee2MQTT, and readings they trust. Aqara Temperature and Humidity Sensor owners single out its coin-sized body that goes into fridges, freezers and covered outdoor spots, and its reach across HomeKit, Alexa, Google Home and Zigbee dongles. Their complaints are a fragile battery cover and a minority of units with much shorter battery life than rated. Sonoff SNZB-02WD owners use it in garages, greenhouses and log stores and like reading the value straight off the LCD, with battery performance they call strong and a redesigned, more secure battery door. Their main criticism is that the reporting interval feels slow when they want fast monitoring.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
