Aeotec Multipurpose Sensor vs Heiman Window Door Alarm

The Aeotec Multipurpose Sensor is better overall. It carries a higher owner rating, supports more integrations (Google Home, Alexa, SmartThings and Home Assistant), and adds temperature and vibration sensing. The Heiman Window Door Alarm wins on price and on being hub-free over Wi-Fi.

How they connect and what they sense. The Aeotec Multipurpose Sensor is a Zigbee multi-sensor that needs a hub but works across major platforms and reads temperature and vibration, while the Heiman Window Door Alarm is a hub-free 2.4GHz Wi-Fi contact sensor with a built-in 65 dB alarm, tied to the Smart Life app, Alexa and Google.

The Heiman Window Door Alarm does. It connects directly to 2.4GHz Wi-Fi through the Smart Life (Tuya) app with no separate hub. The Aeotec Multipurpose Sensor is a Zigbee device that always requires a Zigbee hub.

Buy the Heiman Window Door Alarm if you want a cheap, hub-free Wi-Fi sensor for simple open/close phone alerts, already use the Smart Life app, and like having a built-in 65 dB audible alarm. It is best for basic awareness rather than deep smart-home integration.

Buy the Aeotec Multipurpose Sensor if you want a higher-rated sensor with broad integrations and more than open/close detection, it also senses temperature and vibration for automations. It suits SmartThings, Hubitat and Home Assistant users running a Zigbee hub.
