I was having great trouble commissioning my IKEA buttons. The matter logs were showing the button was being discovered, but then it would disappear less than a second later and commissioning would fail.
And of course, there is no pairing code on the actual device. So i couldnt put the code in manually!
AI guided me however, to take a picture of the barcode, and have google lens convert it into a code. (MT:…)
I then went into the Matter server web interface on HA and hit “Commission” and it then asked for the share code. I inputted the MT:… code and low and behold it commissioned straight away!!
I thought I would share as many people seem to be having similar issues.
