Pairing IKEA Grillplats plug issues - ipv6?

Configuration Matter/Thread
1

Hi all,

I spent several hours trying to get a new set of Grillplats plugs paired to my home assistant server. Keep in mind I already have 25 of these Ikea devices running succesfully via Matter over Thread (Kajplats E27 & GU10 lamps, Varmblixt donut lamp, Myggspray motion sensor, Klippbok water sensor and 3 other Grillplats smart plugs. The network has been stable and still is however I am unable to add these new devices.

Hardware:

  • HA OS on Raspberry PI5 2026.4.2 (was the same on 2026.4.1) connected via LAN IP IPv4: 192.xxx.0.22x (automatic)
  • Sonoff Dongle-E running latest thread firmware
  • Telenet CH8568LG modem - no own router or APs. 2 seperate SSID for 5ghz en 2.4 ghz (I connect to the 2.4ghz one with my Android S23 Ultra phone to commission)
  • Samsung S23 Ultra connected to the 2.4GHz SSID, IP 192.xxx.0.23x. Mobile data turned off during commissioning, bluetooth on. Credentials synced via Settings/Companion app/Troobleshoot
  • IKEA plug freshly reset

The error is not the typical ones about no border router or that the border router cant be found.

My guess is, and that is just a guess, that the device has not been put into pairing mode correctly, that the device have not been fully factory reset or that it is one of those devices that can be switched to Zigbee by holding the reset button longer than a normal factory reset, which might be the case here.

If on HAOS 17.2 try the commands below, as it could be the known issue linked below.

ha docker options --enable-ipv6=true
ha host reboot
