Cannot pair Door and Window Sensor P2 to Aqara Hub M3 via matter

Everything Matter

I have an Aqara HUB M3 and 3 Door and Window Sensors P2. I’m trying to add the Sensors to the hub via matter with the Aqara Home app on my IPhone. And unfortunately that doesn’t work. Can’t pair any of the 3 sensors. The app detects the sensor. Then I scan the matter code. The app says it’s connecting to the sensor. (it detects it is a sensor). Then the app says it’s setting up and that fails after a while.

I am sure the matter network works since there are already other devices connected to the matter hub, 3 aqara motion sensors P2, and about 11 shelly matter plugs. The matter network is also connectd to my home assistant and I can access all matter devices in home assistant as well.

Any ideas what I can do to pair the door & windows sensors to the Aqara hub?

I already searched the internet and didn’t find much I didn’t try yet except forcing everything, hub , phone & sensor to 2,4GHz so I did that , didn’t help

Keen to see what info you get here, I’m in the same boat, I’ve tried everything, P2 Door sensors or even third party matter devices like Lifx Lightbulbs get to step 3 of the setup, and then will ALWAYS fail to proceed.

Could it be added to Apple Home app directly?

Unfortunately, I also couldn’t connect it to Aqara Home directly. If you connect it first to Homekit and take the code there, then it connects to Aqara Home, but without HK or another matter platform, it doesn’t work.

Got it, it looks like the same issue which we discussed in the following thread, Unable to add T2 Bulbs to M3 via Thread & Aqara Response - #2 by AqaraBot

I’ve recently updated my Phone to IOS 18.5 and still can’t add the Door sensors. I’ve tried adding them to homekit but that didn’t work either. So far the devices are completely useless. And, I still can add other devices to my matter network. It’s really related tot he Door sensors.

I am afraid that this issue might be expected to be fixed in iOS 18.6.

There are now already beta versions of IoS 26, any idea if the problem has been solved?

I updated my iPhone to 18.6 beta, but I still have the same error.
I also tried to do the same with Aqara app installed on my Mac. And it is also giving me the same error.
Don’t really want to try ios26 yet…

Thank you for your feedback.

Based on the snapshots you provided, it doesn’t appear to be a bug in iOS 18.4. Instead, it seems that your phone is unable to discover the Primary Matter Hub (M3) on the same local network.

Please make sure that your phone and the M3 hub are connected to the same Wi-Fi network, and check if features like AP Isolation or mDNS are disabled on your router, as they may prevent local discovery.

Let us know if the issue persists after checking these settings.

It helped when I simply switched off all 5 GHz on my router and turned on 2.4 GHz
I was able to connect to my normal Aqara Zigbee devices on 5GHz before.
It says m3 can work on 5ghz network, but it does not in the correct way.

just a FYI I’m using one of the IOS 26 beta versions now and I am able to pair the door & window sensors P2 via the aqara M3 hub.

I was on IOS 18.5 and had trouble adding the P2 sensor to the M3 Hub.

I updated to IOS 18.6 and my first attempt didn’t work.

For the second attempt, I reset the M3 Hub and my P2 sensor. This time it worked.

For context:
iPhone 16 Pro iOS 18.6
P2 sensor v1.0.2.0
M3 Hub v4.3.7_0036

This same thing happened to me. Press the reset button for a long time. Until you see a purple light flash. Then back to blue. After this try to pair again. Should work
