2026 verdict
Despite sitting in the temperature and humidity category, the Aeotec Multipurpose Sensor is really a door and window contact sensor with vibration bolted on, and the Sonoff SNZB-02M AirGuard TH Pressure Sensor beats it on price, rating, battery life, integrations, sensor coverage and alerts because the Aeotec doesn't measure humidity at all. Where the Aeotec earns its keep is as a multi-job device: the same unit that reports rough ambient temperature also catches an opened door or a knock on a window frame, a combination the Sonoff, a dedicated climate sensor, cannot replicate. Both require a Zigbee hub and skip an on-device screen, but the Sonoff's coin-cell battery is rated to outlast the Aeotec's, and it adds humidity and atmospheric-pressure readings the Aeotec's sensor suite simply lacks. Buyers who want a single Zigbee device to watch a door, catch vibration, and glance at temperature should still consider the Aeotec Multipurpose Sensor; buyers who actually need humidity or pressure data should go straight to the Sonoff SNZB-02M AirGuard TH Pressure Sensor.

Frequently Asked Questions
Which is better overall: the Aeotec Multipurpose Sensor or the Sonoff SNZB-02M AirGuard TH Pressure Sensor?
The Sonoff SNZB-02M AirGuard TH Pressure Sensor wins for climate monitoring, costing less, rating higher, lasting longer on a battery, and measuring humidity and pressure that the Aeotec Multipurpose Sensor cannot. The Aeotec is really a door/window contact and vibration sensor with a temperature bonus.
What is the biggest difference between the Aeotec Multipurpose Sensor and the Sonoff SNZB-02M AirGuard TH Pressure Sensor?
Purpose. The Aeotec Multipurpose Sensor is built primarily as a door/window contact and vibration sensor with a basic temperature reading, while the Sonoff SNZB-02M AirGuard TH Pressure Sensor is a dedicated climate sensor measuring temperature, humidity and atmospheric pressure.
Does the Aeotec Multipurpose Sensor measure humidity?
No, it only reports temperature alongside its main open/close and vibration sensing. The Sonoff SNZB-02M AirGuard TH Pressure Sensor measures temperature, humidity and atmospheric pressure.
Which one has the longer battery life?
The Sonoff SNZB-02M AirGuard TH Pressure Sensor is rated for about 2 years, longer than the Aeotec Multipurpose Sensor's roughly 1-year rating, which some owners report running shorter on high-traffic doors.
Who should buy the Aeotec Multipurpose Sensor?
Zigbee households that want one device to cover door/window contact and vibration detection, with rough ambient temperature as a bonus, rather than dedicated humidity or pressure monitoring.
Who should buy the Sonoff SNZB-02M AirGuard TH Pressure Sensor?
Anyone whose priority is actual climate monitoring: room comfort, humidity tracking, or weather-trend data from barometric pressure.
