Aeotec Multipurpose Sensor vs Sonoff LCD Smart Temperature Humidity Sensor

Sonoff LCD Smart Temperature Humidity Sensor for climate monitoring: it adds humidity sensing, a 2.5 inch LCD, humidity and low-battery alerts and two year battery life, at a lower price. Aeotec Multipurpose Sensor wins on platform support, listing SmartThings alongside Google Home, Alexa and Home Assistant.

No. Aeotec Multipurpose Sensor reports temperature only, with humidity absent despite sitting in this category, because it is primarily a door and window contact sensor with vibration detection. Sonoff LCD Smart Temperature Humidity Sensor measures both temperature and humidity and can alert on either.

Sonoff LCD Smart Temperature Humidity Sensor, thanks to its 2.5 inch LCD showing current temperature and humidity at a glance. Aeotec Multipurpose Sensor has no display at all, so every reading has to come through SmartThings, Home Assistant or another hub interface.

Both use a CR2450 coin cell, but Sonoff LCD Smart Temperature Humidity Sensor is rated for about two years against one year for Aeotec Multipurpose Sensor, and several Aeotec owners report shorter life still. Only the Sonoff sends a low-battery alert before it goes quiet.

Yes. Neither has Wi-Fi, Bluetooth or Thread, so both require a Zigbee coordinator such as SmartThings, a Sonoff dongle or Home Assistant running ZHA or Zigbee2MQTT. Owners report fast, reliable pairing on both devices through those routes.

Anyone who wants a single Zigbee device covering a door or window, a knock or vibration alert and a rough ambient temperature, especially on SmartThings. If humidity, an on-device screen and climate alerts are the point, Sonoff LCD Smart Temperature Humidity Sensor is the right sensor.
