Matter Configuration after restore

Configuration Matter/Thread

Hi all,

last year my Home Assistant was running on a raspberry pi 4. I decided to use another hardware - so i made a full backup and restored it.
Everything is working like a charm.

BUT - all my matter devices (51) are offline in Home Assistant. Is there any easy way to bring them back to life? Or do I have to remove them and add them again?

Thank you!

Did you make sure your new device got the same IP and if it was reserved in DHCP then that the MAC address of that reservation needs to be updated too.

Yeah - my new homeassistant has the same IPv4 address.
