Aqara Door and Window Sensor vs Eufy Entry Sensor

The Aqara Door and Window Sensor is better overall. It is more affordable, supports more integrations (HomeKit, Google, Alexa, IFTTT and Home Assistant), and offers more alert types. The Eufy Entry Sensor carries a higher owner rating and excels within the eufy ecosystem.

Openness versus ecosystem lock-in. The Aqara Door and Window Sensor works with HomeKit, Google, Alexa, IFTTT and Home Assistant, while the Eufy Entry Sensor is tied to a eufy HomeBase and triggers eufy sirens and cameras, with no HomeKit, Alexa or Google support.

The Eufy Entry Sensor tends to run longer, with its CR123A cell often lasting 2 to 3 years. The Aqara Door and Window Sensor's CR1632 is rated around 2 years and commonly reaches 1 to 2 years, both are strong, but the eufy's larger battery lasts a bit longer.

Buy the Eufy Entry Sensor if you have or are building a eufy Security system with a HomeBase and want subscription-free door and window coverage that triggers eufy sirens, chimes and cameras. It is reliable with long battery life, but it does not work with HomeKit, Alexa or Google.

Buy the Aqara Door and Window Sensor if you want the cheaper, more widely compatible option with the smallest footprint and long battery life. It is ideal for an Aqara-hub or HomeKit household that wants discreet, low-cost coverage and wide platform support.
