The Aqara Door and Window Sensor is a Zigbee device for an Aqara hub. The Eufy Entry Sensor has no Zigbee: it links to a eufy HomeBase over its own sub-GHz radio, and the HomeBase connects to Wi-Fi.
Aqara works with Apple Home, Google Home, Alexa and Home Assistant, plus Matter and SmartThings through its hub. The Eufy works with Home Assistant and the eufy app only.
The Aqara is 41 x 22 x 11 mm; the Eufy is 73 x 27 x 22 mm and 68 g. The Aqara is the one that disappears on a window frame.
Both are rated for 2 years, the Aqara on a CR1632 coin cell and the Eufy on a CR123A. Battery life is not what separates them.
The Eufy Entry Sensor can trigger a eufy HomeBase siren and eufy camera recordings. The Aqara Door and Window Sensor adds tamper alerts with an Aqara hub and drives automations rather than a siren system.
The Eufy Entry Sensor ties door openings to the HomeBase siren and camera recordings.
The Aqara Door and Window Sensor works with both, while the Eufy does not.
It is a fraction of the Eufy's size.
The Eufy Entry Sensor reaches Home Assistant through the eufy HomeBase, with no Zigbee network to build.
Owners of both describe quick, reliable open and close alerts and easy adhesive mounting, and both groups praise long battery life. Aqara Door and Window Sensor owners single out how tiny it is and the automations it drives in Apple Home, Alexa and Home Assistant, but warn it needs an Aqara hub and can lock up on mixed Home Assistant Zigbee networks. Eufy Entry Sensor owners talk about their HomeBase: sirens, camera recordings and door chimes triggered when a door opens, a customizable app with home, away and night modes, and eufy's responsive support. They complain that the app can break after updates, that it will not show up in Apple Home, Alexa or Google, and that the body is large with a flimsy magnet housing.
The Aqara Door and Window Sensor, for most homes: it works with far more platforms, adds tamper alerts and is much smaller. The Eufy Entry Sensor is the better choice only inside a eufy Security system with a HomeBase.
No. The Eufy Entry Sensor connects to a eufy HomeBase over its own sub-GHz link, and the HomeBase uses Wi-Fi. The Aqara Door and Window Sensor is the Zigbee sensor of the two and needs an Aqara hub.
They are rated the same, 2 years. The Aqara Door and Window Sensor uses a CR1632 coin cell and the Eufy Entry Sensor a CR123A.
No, the Eufy Entry Sensor works with the eufy app and Home Assistant only. The Aqara Door and Window Sensor works with Alexa, Google Home, Apple Home and Home Assistant.
Anyone with an Aqara hub who wants small contact sensors for automations across Apple Home, Google Home, Alexa and Home Assistant.
eufy Security owners with a HomeBase who want doors and windows to trigger the siren and cameras from one app.
