Review: I have several of these, and they have all worked flawlessly for me with Home Assistant - I have not had any of the connectivity issues or reliability issues that some reviewers have had with this product. To date I have purchased 7 of these contact sensors, and they have all been rock solid, in fact theyve been some of the most reliable products in my smart home. If that changes I'll edit this review with an update. They all paired to Home Assistant using Matter quickly and without issue...except for one. One was actually giving me a decent amount of trouble with pairing. I ended up temporarily turning off my Wifi's 5Ghz network, factory resetting multiple times, and retrying multiple times, but it did eventually work, and that sensor has not given me any trouble since. The sensors are also pretty fast to update, and while it's a tad bulky for a contact sensor, the trade-off is that i've gotten great battery life out of them so far. I have no complaints
Review: Very poor reliability. - Worked for 10 minutes and then stopped responding. The adhesive was good though. Stayed up and didn't tear up the paint when I removed it the same day. For a door sensor, at least some reliability is required for security so I will look for a better product.

## Features

- [Native Matter Support over Thread] As one of the first sensors to support Matter, the P2 supports access to Aqara Home, Apple Home, Google Home, desertcart Alexa and Samsung . Meanwhile, as a sensor based on the Thread protocol, the P2 provides enhanced connectivity, low-power consumption, more stability, and low latency.
