AqaraDoor 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 and SmartThings

INSTANT updates! Matter compatibility is true and works amazing. Price is a bit high but I don’t regret buying it. The adhesion is very strong and holds up even after moving it to different doors. Size is pretty small. Amazing sleek look. Would recommend, planning on buying more! Very nice to automate with Apple Home

Big House “3 Aqara Hub M3, 3 HomePod Mini, 4 Apple TV last Gen, 3 Last Gen of Alexa” and great, fast and reliable Mish Network. This is my Smart home base.For Aqara sensors I have the old one, I bought the new Matter sensor, it’s worst difficult to pair it with all smart echo system.It’s was nightmare I couldn’t do anything, I try everything maybe you’ll think it and not pair.So what I did? I erased my whole network, then setup my WiFi from ground up, finally I pair with HomeKit and Aqara app.I found the previous sensor it’s way better fast and it’s showing for how long door open or even if it’s offline.

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.

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 hub2. 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.

It’s great, It looks kinda funny. But it was an easy setup and works great. Although it will disconnect from the internet and not easy to repair. It sticks to the door frame great. It’s kinda big and chunky.

Stop!!!! Buy only if your going to get a home system mainly from this brand, if you want to use it with Google or Amazon or whatever, it will be a mission to connect to the 3rd party controller (AKA :thread board router)I had filled out the amazon return and was ready to head out to return this item, however I wanted to try one more thing, and this is the headache I had to overcome, I had to change my wifi to 2.5hz, turn off easy plug and play, turn off cellular data, and rearrange my thread board router in my units main app (Google home in my case). I don't know what did the trick but I got it and it work after the 15th time. No exaggeration.It does work fast and has a good battery in it. And it feels really well made. I only recommend if your ready for a mission or buying the whole system of the same brand. One more thing, this is one unit alone, the sensor and magnet, Not two or more.

It works great but after a few months it goes offline. I use it at an Airbnb / vacation house to auto Lock the door when they leave. It keeps going offline after a few months. When I go back I have to remove and re-add it to the Aqara hub. I've also tried adding it to a SmartThings hub, Google hub and Home Assistant. Same results. Very aggravating to have to keep resetting it when it's so far away.
