The aggregate ratings lean positive, with most ratings in the five-star category, but a smaller one-star share means experiences are not uniformly favourable. Ratings alone do not identify what worked or disappointed customers. For buyers, the key practical consideration remains whether their hub and Thread setup supports the sensor and desired features.

Frequently asked questions

Does this sensor work without a hub?

No. The listing requires a compatible Matter controller and Thread Border Router.

Can the sensors trigger automations?

The listing says they can control other connected devices when a door or window opens or closes. Availability depends on the selected platform.

Which phones and operating systems are listed?

The stated requirements are iOS/iPadOS 16.4 or later, or Android 8.1 or later, plus a compatible hub.

What is included in the pack?

The explicit included-components entry lists three Eve Door & Window sensors. A separate manufacturer box list also mentions a replaceable battery and Quick Start Guide, but that list describes one sensor rather than the three-pack. Confirm the selected listing's package contents.
