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

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.

Almost too good!
I love the Aqara P2 Door Sensors. They’ve given me peace of mind that my home is safe when I’m on the go!Even non-techies will find the setup of the P2 Sensor easy to accomplish. A warning to the wise, do not remove the sticky tabs until you understand exactly where on the doors the sensor is to be placed. I thought I had them positioned correctly until I realized I would pull the sensor off if I opened the door. I had to pull both parts of the sensor off my door to reposition them, but since the adhesive side is so sticky, I had to pull hard! They grip so well, that I can see them lasting for a lifetime of use.I’ve added the Aqara P2 Sensors and a Kasa Switch garage light switch to the home Apple ecosystem. With the two, I was able to create an automation that instantly turned the Kasa switch on when my Aqara P2 door sensor was triggered and turned off the lights 10 minutes later. I was amazed at how fast the Aqara P2 was able to turn on the Kasa light switch! I had to slowly open the door to see if the lights were actually off, otherwise, it looked like the lights were on before I opened the door it was so fast.This and the ability to ask “Siri, turn off the garage lights” is a huge win!

What I learned, troubleshooting tips
I ordered 6 aqara door sensors after hearing a lot of good things about aqara in general. These sensors use the Matter protocol which requires a Matter hub. For me, my options are Google Nest Hub v2, Hubitat Elevate C8, and Samsung Smartthings. All 3 have Matter and can act as hubs. Some, better than others.Quality-wise, these sensors could be better. Of the initial 6 sensors, 5 setup flawlessly, and 1 refused to pair. I sent it back for a replacement. Another sensor decided to go rogue in it’s first 24 hours. It would disappear and reappear on the network. It isn’t far from the hub, and after the first 24 hours it stopped its weird behavior and worked correctly. One sensor I tried moving from Google Nest Hub to Hubitat, big mistake. First, I couldn’t get the Hubitat to pair with the sensor. For some reason, it could never find it. Then when trying to re-pair it to Google, it would fail. After much screaming, crying, begging and pleading I managed to connect that sensor through Smartthings.What I learned is the provided directions are worthless. Pressing the sensor button a few times and then holding it for about 5 seconds will enter pairing mode. The sensor will respond with a slow flash blue light. If it doesn’t pair, press and hold another 5 seconds and the sensor will flash red. I am guessing that is factory reset even though it is undocumented. Then press for 5 more seconds to get to the slow blue flash to try pairing. If that fails, move the sensor next to the Matter hub. Try pairing. If that fails, reboot the hub. I had a problem pairing the replacement sensor that rebooting the Google Nest Max Hub fixed. If that fails, try a different hub, like Smartthings. I hope this helps some of you having pairing issues.Update: For those having trouble getting the P2 contact sensor on Hubitat, here’s how to do it with the Google Nest Hub or Max. 1. Factory reset the P2 sensor. 2. Pair it to your Google Nest Hub or Max. 3. Immediately (do not wait), open the sensor on the Google Home app and click the gear icon. 4. Click Linked Matter apps & services. 5. Click Link apps & services. 6. Click Use pairing code. 7. You have 3 minutes to open your Hubitat app, go to Devices, Add a device. 7a. Click Matter. 7b. Enter that code in the Matter setup code box. If you were fast enough it should get recognized by your Hubitat. Good luck!

Five stars…after some issue resolutions
These are wonderful, but you have to do a few things if you’re having issues. I tried connecting one and it was not working at all. So I tried to set up another and the same thing happened.Since both were not working I figured it was something with my network. Turns out my mesh router (Google Nest Wifi Pro) was conflicting with my router (whatever ATT gave me). The ATT router had its WiFi signals enabled for 2.4Ghz and 5Ghz so when the set up was happening, it was picking up both WiFi connections from my phone. I disabled the signals from the ATT router, and they still weren’t working, but I wanted to try a third just in case, and it magically connected easily.Since that started working, I wanted to troubleshoot the other two that were still having issues. I figured hat during the setup, the devices remembered the settings so I needed a way to reset them and start fresh. I saw a video from their YouTube account that you can factory reset if you press the button 10 times.Once I did that, both connected easily.I bought 13 of these and never had an issue setting up the other 11 after the network issue / factory reset took place. They are easy to set up and don’t get in the way.Finally I used the extra magnets that came with each device on my fridge, lol.

This couldn’t be any easier to use! Paired with my u200 lock; This ensures my door is always locked when the door is closed. I no longer have to rely on the finicky gyroscope in the u200. I use Apple homekit. My door locks immediately it’s closed.If you use apple homekit and have HomePods and iPhone etc, you should be good. I can’t speak for any other smart home system.I will update my review if anything changes.

Ya era hora de que salieran sensores que no necesitan el típico hub del fabricante o su app y que no cuestan 40€ o 50€. Es de Aqara pero no necesitas instalar apps de Aqara, ni dar datos personales a Aqara ni comprar hubs de Aqara.Es un sensor de contacto, uso típico en puertas, que funciona con Matter over Thread. Aunque no necesita hub de Aqara sí necesitas el hub Matter y Thread de tu plataforma domótica (un Echo 4, un Nest Hub 2, Homepod mini, etc.).Al grano: es muy recomendable, yo lo compré con la promo de lanzamiento del 20% de descuento (26 euros). Ha sido una compra casi a ciegas porque casi no hay reviews (salió el 6 de julio), pero está genial.Yo lo he probado con Google Home y el Nest Hub 2 que hace de controlador Matter y Thread border router. La instalación es básicamente darle a añadir dispositivo en la app de la plataforma domótica y escanear un QR que viene en el manual impreso. A la primera funcionando, parece que Matter ya empieza a funcionar como se espera.Si bien ya había un sensor de puerta Matter over Thread de la marca Eve, ese cuesta bastante más y usa unas pilas rarísimas difíciles de encontrar y que pocas marcas fabrican. El Aqara usa CR123A que, no siendo la más habitual del mundo, la venden hasta en el hipermercado de mi barrio.Evidentemente no sé cuánto dura la pila porque acaba de salir y Aqara no da una cifra porque depende del uso que tenga. Me acordaré de actualizar esto cuando se acabe. En teoría Thread no consume mucho, pero Matter lleva encima toda la capa de seguridad, cifrado, etc. que puede que gaste algo más.Incluyo una foto para que se vea el tamaño. Es grande, o más bien largo, para ser un sensor de contacto pero tampoco es inmenso y no queda mal en la puerta como se ve en otra de las fotos.El vídeo creo que es lo que más va a interesar. Es una rutina hecha en Google Home con el nuevo editor de automatizaciones. El starter es device.state.OpenClose, porcentaje 0 cuando está cerrado, 100 cuando está abierto. En acciones estoy controlando una bombilla Matter de la marca WiZ, así que es el caso mejor en cuanto retardo porque no hay nubes de terceros involucradas.De momento las pruebas que he hecho funciona bien, me he ido lejos del Thread border router (hasta cuatro habitaciones más allá) y también ha ido bien. Si noto algo raro actualizaré por aquí, pero de momento merece 5 estrellas y en dos días de pruebas varias no ha fallado ni una sola vez y ya he decidido pegarlo a la puerta. Antes no quería pegarlo por si acaso tocaba devolverlo :)Actualización (1 de agosto 2023): Anoche hubo un apagón eléctrico que duró unos segundos. Al Nest Hub que hace de Thread border router no debió sentarle bien (tampoco a un enchufe inteligente que se desconfiguró) y perdió conexión con el sensor. Con apagar y encender el Nest Hub la recuperó. Por lo demás en este mes no ha fallado ninguna vez la detección de apertura así que sigo recomendándolo.Actualización (1 de septiembre 2023): Sigue yendo perfectamente, ahora en Google Home se puede automatizar directamente desde la app también, no hace falta el editor de scripts como al principio. Por cierto, veo alguna mala puntuación de gente diciendo que no le funciona con un Echo Dot, ¡claro que no!, es necesario un router Thread y el Dot no sirve para eso, el Echo 4 (no dot) por ejemplo sí.

Appareil assez discret et s’installe assez facilement.J’ai pu paramétrer l’appareil pour recevoir une notification sur ouverture de la porte quand je ne suis pas à la maison.Fait donc bien le boulot demandé.

「SESAMI 5 Pro」というスマートロックの開閉センサーとして購入しました。Switchbot社の開閉センサーではGooglehomeで他社製品を制御、操作出来ないとの事で、Matterに対応しているこの製品を選んだ。Googlehomeに追加しても開閉の判断が可能で、オートメーションにも組み込むことが出来る。お陰で目的であったスマートロックの開閉センサーとして使用出来た。
