The Aeotec Multipurpose Sensor is the more versatile door and window sensor of this pair, rated higher than the Heiman Window Door Alarm and covering more than contact alone. It reaches Google Home, Alexa, SmartThings and Home Assistant over a Zigbee hub, and adds temperature sensing, vibration detection and temperature alerts that the Heiman Window Door Alarm does not offer. The Heiman Window Door Alarm counters with the lower price of the two and needs no hub at all, connecting straight to 2.4GHz Wi-Fi through the Smart Life app with a built-in 65 dB siren. Pick the Aeotec Multipurpose Sensor for a versatile sensor on an existing Zigbee hub, and the Heiman Window Door Alarm for the cheapest way to get standalone Wi-Fi alerts with a local alarm.

What the differences mean

Hub requirement

The Aeotec Multipurpose Sensor is a Zigbee device that always needs a hub such as SmartThings, Hubitat or Home Assistant, while the Heiman Window Door Alarm joins 2.4GHz Wi-Fi directly through the Smart Life app with nothing else to buy.

What it senses

Beyond open and close, the Aeotec Multipurpose Sensor also reads temperature and detects vibration, useful for knowing when an appliance finishes or catching a knock on the door. The Heiman Window Door Alarm senses contact only, but adds a built-in 65 dB siren the Aeotec does not have.

Platform reach

The Aeotec Multipurpose Sensor connects to Google Home, Alexa, SmartThings and Home Assistant through its hub. The Heiman Window Door Alarm is confirmed only with Google Home and Alexa, with no SmartThings or Home Assistant support documented.

Battery type

The Heiman Window Door Alarm runs on a replaceable CR2 cell rated around 2 years. The Aeotec Multipurpose Sensor uses a CR2450 rated for about 1 year, and owners report it can drain faster under heavy vibration reporting.

What owners say

Owners of both sensors say the core job, reporting a door or window opening, works reliably once installed. Aeotec Multipurpose Sensor owners single out how well it tolerates a wide or misaligned gap and like using its vibration reading to catch a knock or know when an appliance finishes, but they warn the CR2450 battery can drain within weeks and that SmartThings shows it as two separate devices. Heiman Window Door Alarm owners like that setup needs no hub and that the same Smart Life app covers their other Tuya gadgets, but several say the app cannot customize the alert sound, so a silenced phone can mean a missed notification, and a minority report units that stop notifying after a day or two.
