Aqara Door and Window Sensor P2, Matter Over Thread, Requires Thread Border Router, Contact Sensor with Remote Alarm and Local Automation, Supports Apple Home, Google Home, Alexa

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

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.

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!

a disclaimer: I actually use this as a way to tell if my deadbolt is locked or not rather than the door being closed. But for everything else my impressions are the same. This is a pretty good product! I pull it out of the box. Set up a new device in google home. Scan the QR code. Wait a minute for google to finish the set up. Stick it where it needs to be stuck. Reapply it with some duck tape after the sensor fell off a few minutes after I set it. Yeah, the adhesion is great... after the glue has had time to set properly. So far that first time was the only time it's fallen off in the month that I've had it. So you just need to make sure that it is supported in some way for at least a few hours to a full day and it should be good after that. The software experience was almost dumb in how simple it was, which is exactly how a smart home device should be. It should be as close to plug-and-play as possible. The Matter standard makes this semi-feasible. I needed it to have matter for a different reason though. The long and short of it is that I don't have access to 2.4 ghz wifi, only 5ghz. So any smart device I get has to be able to connect to my nest hub in some way. Previously this meant scrouring for the rare smart devices that could connect to it with Bluetooth. But now that Matter is getting into the swing of things I actually have some options. And through matter its actually faster to respond than my old wifi and bluetooth devices! The bad news with that is that Matter is still a very new standard. With that come a few trade offs: 1. you need a matter hub 2. The new tech tax is certainly in effect here. While I'll take having an expensive option over having none at all. 30 dollars for a door sensor is pretty steep. (I got it on a black friday sale for around 20 though so keep checking if you want to save some money) But thats just something that comes with the territory I guess. So far all of the matter devices I'v bought have been more expensive than non matter counterparts. I'm sure as time goes on Matter will get support accross the spectrum of smart devices and prices will go down as the tech matures. But for right now we are still in the early adopter phase and you'll be expected to pay a little more.. As far as the sensing part of things. It works. That's about it. It actually comes with 2 magnets which is nice. A pretty, white pill-looking one. As well as a flat, plain metal one that you can use instead of the pill if your situation demands a smaller profile. I do wish they would have put some way of knowing where the sensor needs to line up with the magnet to get it to work so that I didn't have to experiment with alignment as much. But that's a more minor gripe.

Getting my Openthreads border router setup in Docker to use this was a real pain in the... you know, but so far this sensor has been great. It reliably detects when the door is closed or open. They include an extra magnet in case the little white cylinder shaped one won't work, like with a sliding cabinet. Pro tip for the included adhesive: If you do need to relocate this, remove it slowly, lifting form a corner. Then you can clean the adhesive with alcohol to renew it. I was able to restick mine fine in another location without applying new adhesive. I think these get poor reviews because Matter had a rough start, and it's not always as straightforward as Zigbee or other solutions, but after getting this going it's been solid. I've had it going a couple of weeks and the battery is still at 100%, but that could be lack of calibration for to full voltage. I'll try and report back if it becomes an issue.

アップルホームキットに接続できたが、しばらくしたら、接続できなくなりました。

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.

「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。
