It is the lower priced of the pair, and it brings Matter over Thread with Apple HomeKit, Alexa, Google Home, SmartThings and Home Assistant, plus a 2-year battery, none of which the Eufy Entry Sensor matches. The Eufy Entry Sensor answers with the higher owner rating and tighter integration with eufy cameras and sirens through a HomeBase. Neither is weatherproofed, and both run on a CR123A cell. Pick the Aqara Door and Window Sensor P2 for an open, no-vendor-hub setup, and the Eufy Entry Sensor when the rest of the house is already eufy Security.

What the differences mean

Connectivity and platforms

The Aqara Door and Window Sensor P2 speaks Matter over Thread, pairing with Apple HomeKit, Alexa, Google Home, SmartThings and Home Assistant and needing only a Thread border router. The Eufy Entry Sensor needs a eufy HomeBase and works with neither HomeKit, Alexa, Google nor Matter.

What triggers

The Eufy Entry Sensor ties into the wider eufy system, triggering the HomeBase siren, camera sirens, recordings and chimes. The Aqara Door and Window Sensor P2 is a standalone Matter sensor whose automations are set up in your platform of choice.

Firmware updates

The Aqara Door and Window Sensor P2 can only update its firmware with an Aqara hub, which undercuts the no-hub pitch. The Eufy Entry Sensor updates through the HomeBase it already requires.

Mounting gap

The Aqara Door and Window Sensor P2 tolerates a wide gap between sensor and magnet, so it mounts on trimmed doors where other sensors will not register closed. The Eufy Entry Sensor needs its two halves within about 4 cm.

Rating

The Eufy Entry Sensor carries the higher owner rating, reflecting a longer track record, while the Aqara Door and Window Sensor P2's rating reflects mixed reports around its still-maturing Thread implementation.

What owners say

Owners of both sensors care about fast, reliable open-and-close detection, and both groups describe easy installation with strong adhesive. Aqara Door and Window Sensor P2 owners pair it straight to a Thread border router by scanning a Matter QR code, love the wide sensor-to-magnet gap that fits trimmed doors, and report detection accurate enough that lights fire almost instantly, but a notable share describe disconnects that need a full factory reset and re-pair, plus individual units that drain a fresh CR123A in days. Eufy Entry Sensor owners praise how it triggers eufy sirens, camera recordings and chimes with no monthly fee, reliable 1 to 2 second response and CR123A batteries that last two to three years, and they warn that it needs a eufy HomeBase and has no HomeKit, Alexa, Google or Matter support.
