With an Aqara hub it works with Apple Home, Google Home, Alexa and Home Assistant, bridges to Matter and SmartThings, and adds tamper alerts, in a 41 x 22 x 11 mm body against 73 x 27 x 22 mm. The Eufy Entry Sensor is a security accessory rather than a smart home one: it pairs with a eufy HomeBase, sets off its siren and eufy cameras, and owners like that no monthly fee is involved, but beyond the eufy app it reaches only Home Assistant. Both batteries are rated for 2 years. Pick the Aqara Door and Window Sensor for automations across platforms, and the Eufy Entry Sensor to add entry alerts to an existing eufy HomeBase.

What the differences mean

Hub and radio

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.

Platforms

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.

Size

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.

Battery

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.

Alarm integration

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.

Which one to buy if

What owners say

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.

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.
