Aqara Door and Window Sensor P2 vs Eufy Entry Sensor comparison

Updated August 2026

Data from Amazon and official Aqara and Eufy sites.

2026 verdict

The Aqara Door and Window Sensor P2 wins this door and window sensor matchup on price, connectivity, integrations and alerts, thanks largely to its open, no-hub Matter over Thread design. It pairs directly to an Apple TV or HomePod and works with HomeKit, Google, Alexa, SmartThings, Home Assistant and IFTTT, adds tamper and automation alerts, tolerates a wide sensor-to-magnet gap for trimmed doors, and is the more affordable option. The Eufy Entry Sensor holds a higher owner rating and is a very reliable, dependable performer, but it is locked to the eufy Security ecosystem: it needs a eufy HomeBase and works only with Home Assistant beyond that, with no HomeKit, Alexa, Google or Matter, though it triggers eufy sirens and cameras with no subscription and lasts two to three years on a CR123A. Pick the P2 for cheaper, widely compatible Matter over Thread; choose the Eufy if you already run a eufy HomeBase and want subscription-free, siren-linked door coverage.

Frequently Asked Questions

Which is the better contact sensor, the Aqara Door and Window Sensor P2 or the Eufy Entry Sensor?

The Aqara Door and Window Sensor P2 wins overall on price, connectivity and integrations, offering no-hub Matter over Thread and support for HomeKit, Google, Alexa and more. The Eufy Entry Sensor carries a higher owner rating but only works within the eufy Security ecosystem.

What is the main difference between these two?

Openness. The Aqara Door and Window Sensor P2 uses Matter over Thread and integrates with HomeKit, Google, Alexa, SmartThings and Home Assistant, while the Eufy Entry Sensor requires a eufy HomeBase and does not work with HomeKit, Alexa, Google or Matter.

Which sensor is more flexible across smart-home platforms?

The Aqara Door and Window Sensor P2 by far. It reaches HomeKit, Google, Alexa, SmartThings, Home Assistant, IFTTT and Matter with no dedicated hub. The Eufy Entry Sensor is tied to a eufy HomeBase and only adds Home Assistant beyond eufy's own app.

Which is the more dependable, worry-free sensor?

The Eufy Entry Sensor is the steadier, higher-rated performer, very reliable within a eufy HomeBase system with two to three years of CR123A battery life. The P2's Matter/Thread firmware is newer, and some owners report disconnects that need a re-pair.

Who should buy the Aqara Door and Window Sensor P2?

Buy the Aqara Door and Window Sensor P2 if you want cheaper, no-hub Matter over Thread with the widest platform support including HomeKit, plus a wide sensor-magnet gap for trimmed doors, and you have a Thread border router.

Who should buy the Eufy Entry Sensor?

Buy the Eufy Entry Sensor if you already run a eufy Security HomeBase and want subscription-free door coverage that triggers eufy sirens, chimes and cameras, with a higher owner rating and multi-year battery life.
