Hi, I have a homneassistant running on a Pi 4 and now have to move to a Pi 3. I reinstalled HA on the Pi 3 and restored the backup. Everything is back so far … just the matter devices are listed but it looks like not connected. Can’t I migrate them just doing the restore ? My matter experience is not that good on HA 
Thank you for an advise. Reconnecting and again configuring tooks very long bacause names are not shown as on my Aqara App
Regards Stefan
