It joins 2.4 GHz Wi-Fi directly through the Smart Life app, costs less, works with Google Home and Alexa, and sounds its own 65 dB alarm. The Eufy Entry Sensor is the better liked of the two and the one to buy inside a eufy Security system: through a HomeBase it triggers sirens, chimes and camera recordings with no monthly fee, and it works with Home Assistant. Both are rated for 2 years per battery and both are indoor sensors with no Apple Home or Matter support. Pick the Heiman Window Door Alarm for simple phone alerts without a hub, and the Eufy Entry Sensor if you own eufy cameras and a HomeBase.

What the differences mean

Hub

The Heiman Window Door Alarm connects straight to 2.4 GHz Wi-Fi and works with the Smart Life app on its own. The Eufy Entry Sensor needs a eufy HomeBase, which it reaches over a sub-1 GHz link, so it is useless without one.

Voice assistants

The Heiman works with Google Home and Alexa. The Eufy Entry Sensor works with neither, since the eufy skill does not expose HomeBase sensors, but it does work with Home Assistant, where Heiman support is not documented.

Alarm

The Heiman Window Door Alarm has a built-in 65 dB buzzer. The Eufy Entry Sensor has no siren of its own but can set off the HomeBase siren and eufy camera sirens, which is a much louder, whole-system alarm.

Batteries

Both are rated for 2 years. The Heiman uses a CR2 cell and the Eufy Entry Sensor a CR123A, a less common battery that owners say lasts a long time.

Which one to buy if

What owners say

Owners of both sensors value simple, dependable awareness of a door opening, and both groups report an easy adhesive install. Eufy Entry Sensor owners single out how it ties into their eufy system, sirens, chimes and camera recordings with no subscription, a quick 1 to 2 second response and a CR123A cell that lasts years; their complaints are no HomeKit, Alexa or Google support, an app that can break after updates and a flimsy magnet housing. Heiman Window Door Alarm owners like needing no hub and using the same Smart Life app as their other devices, often to know when a child or a relative with dementia opens a door; they complain that the app cannot customise alert sounds, of a couple of seconds of delay, and that some units stop notifying.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
