Hello,
I am trying to add the Ikea MYGGSPRAY sensor to homey pro 2026 via matter over thread. Tried every possible route by adding, factory reset of the sensor but no luck. I got below screens with the error. Anyone have an idea what to do? I searched for other topics on the forum but did not find anyone with a solution…
Checked the knowledge base as well?

Use the pair with Android method or iPhone equivalent
The Homey method isn’t ideal unless you’re right next to the hub
Thanks for all suggestions.
Tried it all, device is 2cm away from Homey. Wifi is not on 1, through homey or Android connecting does not improve..
So what to do?
I have a ticket about ikea matter products. Same screen, issue. It worked for a few weeks but then all collapsed after an “up”date. Don’t let anyone tell you it’s your problem or you should put more effort in this. Homey does simply not have this under control. Do not buy ikea matter until they do (hopefully permanent then)
Hi,
Just taken out of the box two brand new MYGGSPRAY sensors and no way to pair with HomeyPro 2026 
I have 15 IKEA devices, all Matter over Thread, all working fine and actually performing much better since Homey firmware v13.1.
User error should always be the first concern.
Wifi is not on?
You need WiFi on to be able to pair using Android and it must be on the SAME LAN as your Thread network and SAME LAN as your Homey Pro.
If you’re using any kind of VLANs or different subnets, that could be the issue.
Alternatively, if you have Unifi access points, then it’s likely an issue with IPv6.
Did you find the KB link a few posts back?
There’s not just one way to add the devices. You need to know a few things.
Matter only works with Wi-Fi 2.4 so if you have muliple like I have 2.4, 5 and 6 you must change in the router or firewall to use only Wi-Fi 2.4 when you try to connect Matter.
MYGGSPRAY is a Matter over Thread device, so first communication is over bluetooth where sensor is paired and keys of HomeyPro Thread network are shared to the sensor, once this is done all later communication is over Thread. I don’t see a point with WiFi involved in here, except possible Thread interference with 2.4 WiFi channel 11.
Indeed didn’t check initially KB. However Android way neither is working, anyway I see MYGGSPRAY device in bluetooth discovered devices on Android. However during the activation with Android it stuck on communication over Thread with HomeyPro. My HomeyPro is using 5G WiFi, the same as Android device and when I check Thread settings in HomeyPro app I see border router available - yes.
Both my MYGGSPRAY are starting to behave erratically now
False positives, dropping off the thread mesh. Taking ages to re-pair.
Firmware must be bunk.
Same issue here, added to Homey once while homey is connected with ethernet. Put the Ipad on 2.4 wifi and add the sensor. Then within some days not working anymore. Can’t reconnect anymore. Added to the dirigera however these sensors will not be shared through the dirigera app in homey.
Just sharing my experience of pairing Myggspray with Homey Pro 2026. I have an Android phone, not an iPhone.
I have two Myggspray sensors. For the first one, I was able to pair it successfully as a Matter device without using any Homey app. However, the same could not be said for the second Myggspray, I kept getting the error of not finding the device. Eventually I used Homey official IKEA Home Smart app to pair it and succeeded.
