The Sonoff SNZB-02P Temperature & Humidity Sensor is rated for 4 years on a CR2477, the Aqara Temperature and Humidity Sensor for 2 years on a CR2032. Over a house full of sensors, that is half as many battery changes.
Only the Aqara Temperature and Humidity Sensor reports atmospheric pressure. If you want a barometer trend in a weather dashboard, that is the reason to pick it; for plain climate monitoring it does not matter.
The Sonoff SNZB-02P Temperature & Humidity Sensor lists low-battery alerts. The Aqara Temperature and Humidity Sensor does not document them, so a dying cell is easier to miss unless your hub shows the level.
The Sonoff SNZB-02P Temperature & Humidity Sensor works with Google Home, Alexa and SmartThings directly, and reaches Apple Home and Matter through a SONOFF hub. The Aqara Temperature and Humidity Sensor reaches all of them through an Aqara hub.
The Aqara Temperature and Humidity Sensor is 36 x 36 x 9 mm and 13 g, while the Sonoff SNZB-02P Temperature & Humidity Sensor is 45 x 45 x 17.7 mm and 15.5 g. Both are small, but the Aqara is the one that disappears.
The Sonoff SNZB-02P Temperature & Humidity Sensor is rated for 4 years on one cell, twice the Aqara Temperature and Humidity Sensor.
The Aqara Temperature and Humidity Sensor pairs with it directly and reaches Apple Home and Matter through that hub.
The Aqara Temperature and Humidity Sensor is the only one of the two with an atmospheric pressure sensor.
The Sonoff SNZB-02P Temperature & Humidity Sensor pairs with both and warns you when the battery is low.
Owners of both Zigbee sensors praise readings that hold up against dedicated thermometers and the convenience of scattering several around the house. Aqara Temperature and Humidity Sensor owners single out the tiny size that fits in fridges, freezers and covered outdoor spots, plus easy pairing across Aqara hubs, third-party dongles and HomeKit. They complain about a fragile battery cover and a minority of units draining far faster than rated. Sonoff SNZB-02P Temperature & Humidity Sensor owners talk about how reliable it stays once paired, the magnetic mount and the battery that goes years between changes, working smoothly with Home Assistant, Zigbee2MQTT and Echo devices with a built-in Zigbee hub. Some of them report pairing trouble with particular hubs.
The Sonoff SNZB-02P Temperature & Humidity Sensor, thanks to its 4 year battery rating, low-battery alerts and broader native platform support. The Aqara Temperature and Humidity Sensor is better for atmospheric pressure and for homes built around an Aqara hub.
Battery life and sensing. The Sonoff SNZB-02P Temperature & Humidity Sensor lasts 4 years on a CR2477 against 2 years on a CR2032, while the Aqara Temperature and Humidity Sensor adds an atmospheric pressure reading.
Yes. Both are Zigbee devices with no Wi-Fi or Bluetooth, so they need an Aqara or SONOFF hub, a third-party Zigbee dongle used with Home Assistant, or an Echo with a built-in Zigbee hub in the Sonoff's case.
Both, through their own hub. The Aqara Temperature and Humidity Sensor needs an Aqara hub and the Sonoff SNZB-02P Temperature & Humidity Sensor needs a SONOFF hub such as the Zigbee Bridge Ultra, iHost or NSPanel Pro.
People who already have an Aqara hub, want pressure readings, or need the smallest sensor for a fridge, a freezer or a tight shelf.
Home Assistant, Zigbee2MQTT and Echo owners who want to spread many sensors around a house and forget about the batteries for years.
