Aeotec Multipurpose Sensor vs Aqara Door and Window Sensor

The Aqara Door and Window Sensor wins overall. It is the more affordable pick, its CR1632 battery lasts about 2 years against roughly 1 year for the Aeotec Multipurpose Sensor, and it supports more integrations including Apple HomeKit, IFTTT and hub-based Matter. The Aeotec sensor counters with a higher owner rating and extra temperature and vibration sensing.

Battery life and breadth versus versatility. The Aqara sensor is a tiny, discreet contact sensor with about 2-year battery life and wide platform support (HomeKit, Alexa, Google, IFTTT, Home Assistant, Matter via hub), while the Aeotec Multipurpose Sensor adds temperature and vibration sensing but has shorter battery life and fewer confirmed integrations.

The Aqara Door and Window Sensor does. Its CR1632 cell is rated around 2 years and owners often report even longer, while the Aeotec Multipurpose Sensor's CR2450 is rated about 1 year. If you want to change batteries as rarely as possible, Aqara is the clear choice.

Buy the Aeotec Multipurpose Sensor if you want a higher-rated sensor that does more than open/close, it also reads temperature and detects vibration and tilt for automations like knowing when an appliance finishes. It suits SmartThings, Hubitat or Home Assistant users who want a flexible multi-sensor on a Zigbee hub.

Buy the Aqara sensor if you want the smallest, cheapest sensor with the longest battery life and the widest integrations, including Apple HomeKit and IFTTT. It is ideal for an Aqara-hub or HomeKit household, though a mixed Zigbee network with third-party repeaters can cause reliability quirks.
