I have one location (in Bucharest) where the 6,27 landend on both V2 and V3 (with all the Matter/Thread stuff) (Zigbee/Zwave stuff on V2 never ever gave me problems)
My Matter stuff looked like a christmass tree with some Kajplats lamps going off and on. Nothing reacting any more on sensors or Birlesa’s.
I had 5 (five) Ikea matter devices offline before 62.7 was installed and also after 62. stayed offline.
But then: What do you know? I re-power booted the V3 and, quite fast everything came online and everything working etc.
I even have the feeling that Mygspray sensors are working faster and also reacting on Bilresa is faster. But that could be just my personal idea. I am just a simple end user.
I am leaving now for another location, in Romania, and am curious if the five/six Matter devices (Alpstuga/Timmerflotte/Klippbok) will come online just by repowering the V4 0.62.7hub.
Edit. Nope. Power cycled the hub, but the 5 devices did not come to live automatically. The Klippbok only needed battery out and in, the alpsuga off and on, but the Timmerflotte’s needed the whole procedure to become online. Maybe keeping that small inside button somewhat longer pressed helped.
Apropos. Its a building in the middle of nowhere in Romania. Internet is fiber, but the 4 Kajplats bulbs are sometimes flickering. Normal led bulbs don’t flicker here, so it could be the elecronics in the Kajplats
