The Sonoff SNZB-02M AirGuard TH Pressure Sensor wins on price, owner rating, warranty and alert coverage, though the two are otherwise very close, both measuring temperature, humidity and atmospheric pressure over Zigbee.
There isn't a huge structural gap, both are Zigbee sensors covering the same three readings. The real differences are the Sonoff's lower price, higher rating and built-in alerts against the Aqara's IFTTT support, which the Sonoff's spec sheet doesn't list.
Yes, unusually so. Both the Aqara Temperature and Humidity Sensor and the Sonoff SNZB-02M AirGuard TH Pressure Sensor measure temperature, humidity and atmospheric pressure, and both are rated for roughly two years on a single coin-cell battery.
The Sonoff SNZB-02M AirGuard TH Pressure Sensor does. The Aqara Temperature and Humidity Sensor does not list SmartThings support, though it does support IFTTT, which the Sonoff's spec sheet does not confirm.
Buyers already inside the Aqara or Apple HomeKit ecosystem, or who specifically want IFTTT automations tied to a temperature and humidity sensor.
Most Zigbee households, since it costs less, rates higher, and includes built-in humidity and low-battery alerts without extra setup.
