Unable to pair IKEA Matter devices to HA

I just bought some of the new IKEA Matter devices (a Bilresa 2-button switch, and Myggbett contact sensor) today, and am having issues adding them into HA.

I have an Apple TV 4K, so that is my Matter/Thread border router, and while I wasn’t able to pair the devices with HA first, I was able to pair them into Apple HomeKit.

I tried to get them into HA by going to Settings → Devices & Services → Matter → Add Device → (Device already connected to another controller) → Apple Home. Copied the setup code from the Home app after putting the device into pairing mode, and HA spins for a couple of minutes and then gives me an unhelpful message of “Failed to add the device.”

I’m wondering if either anyone has had this issue with these IKEA Matter devices already and managed to work around it (if so, what did you do), or if there’s a way to get some useful logging out of HA to help figure out what’s going wrong.

HA Core version 2026.1.2
OS Version: HAOS 16.3

Thanks,
-Jay

Your setup is probably one of the easiest, so my guess is that your HA does not have IPv6 enabled (or it is on a different network than your Apple TV4K).
Goto UI->Settings->System->Network and make sure IPv6 is enabled for “automatic”.

Hi, and thanks for the reply.

My HA server is on the same network as the Apple TV.

HA : 172.25.10.7/24
Apple TV: 172.25.10.54/24

IPv6 was not turned on in HA. I enabled it to Automatic, waited a few minutes, copied the setup code from the Home app and tried to pair the device in HA; no luck - still failed.

From the same HA networking UI, what IPv6 addresses are showing up?

I did roughly the same except I paired them with the Dirigera first. I don’t have any apple stuff. Then I added them as Matter devices in HA. Tried both as Homekit device and “Other” both worked with the code I got from Dirigera. I did not put the devices in pairing mode when I added them to HA. I don’t think that’s necessary.

ok - glad this just isnt me. I have a bunch of apple thread border routers and even the HA otbr but I can not get this one button to pair. I bought this, their air quality sensor, leak detector sensor and temp/humidity sensor and all of those connected right away. This switch is the only one that I can not get on, and its not really clear to me if I’m putting it in the right pairing mode or even factory reset mode. Like I said the others connected to thread right away and have been working fine

fd04:8650:a8dd:f676:8455:5a18:3b41:9361/64 and
fe80::1121:83ac:5cd1:1155/64

Also, see post below.

I’ve managed to now get the BILRESA switch paired with HA directly (not through HomeKit first) - might well have been the missing IPv6 issue.

I also managed to get one of the MYGGBETT sensors paired - also with HA directly.

But the other MYGGBETT sensor won’t pair with HA. It paired with HomeKit through the Apple TV, but it won’t pair additionally to HA, nor with HA directly.

The new Ikea Matter series seems difficult to pair. I use a Conbee 3 Zigbee dongle to connect Zigbee devices to HA. I had trouble pairing the Kajplats GU10 LED bulbs, but I found a way to pair them easily.

  1. Place your bulb within 50 cm of your Conbee.
  2. Turn the bulb on and off 12 times, and leave it on for the 12th time.
  3. The bulb will now flash a few times and enter pairing mode.
  4. Search for a new device in ZHA. It should find it within a minute.
    The next step is to figure out how to pair the Myggbett…

I have Home Assistant freshly set up with a SLZB-MR2 Thread Border Router and still I cant get to connect my Ikea air quality sensors (Alpstuga). I dont know what the issue seems to be I have IPV6 enabled everywhere. I have the same problem as you but havent found any solution yet.

I am having pairing problems too with the new Ikea range.

  • Timmerflotte Temprature and Humidity sensor
  • Bilresea Smart Button

My hardware is:

  • Home Assistant Green
  • Home Assistant Connect ZBT-2

The ZBT-2 is set up using thread and acts as a border router. Has anyone managed to connect any new Ikea devices with just this hardware (using thread and matter) ?

I’m using HA with a ZBT-1 flashed to Open Thread. Got my first Kajplats bulb to connect by scanning the code on the bulb (the one one the box was so badly printed that it wouldn’t scan) using HA add matter device. Then plugged it in and waited, and it just worked. The ZBT-1 integration seems to work better than many other approaches.
