Aeotec Multipurpose Sensor vs Sonoff SNZB-02WD

The Sonoff SNZB-02WD wins as a temperature and humidity sensor. It measures humidity, has a built-in LCD, sends humidity alerts, adds IP65 weather resistance, and costs less. The Aeotec Multipurpose Sensor carries a higher owner rating and wider integrations plus vibration detection, but it has no screen and does not measure humidity.

The Sonoff SNZB-02WD is a dedicated, screen-equipped, IP65 temperature and humidity sensor, while the Aeotec Multipurpose Sensor is a Zigbee contact and vibration sensor with a temperature reading, no humidity sensor and no display.

Only the Sonoff SNZB-02WD. It has a built-in LCD showing temperature and humidity and an IP65 rating for damp or outdoor spots like garages and greenhouses. The Aeotec Multipurpose Sensor has neither a screen nor a weather-resistance rating.

The Aeotec Multipurpose Sensor lists broader support: Google Home, Alexa, SmartThings and Home Assistant. The Sonoff SNZB-02WD's confirmed integration is Home Assistant. Both are Zigbee-only and require a hub, and neither supports Apple HomeKit.

Home Assistant users who want a durable temperature and humidity sensor with an on-device screen for garages, greenhouses, bathrooms or outdoor spots, thanks to its IP65 rating and LCD readout.

SmartThings and Home Assistant users who want broad voice-assistant support and door/window plus vibration detection with a temperature bonus, rather than dedicated humidity sensing or an on-device display.
