Matter Devices Unavailable after power-cycle

After a series of power cycles (~3 from a power outage) all of my matter devices have stopped working. This entity is no longer being provided by the matter integration. If the entity is no longer in use, delete it in settings.

This has happened to me before when messing with POE and I had to reset each device and repair them. Anyone have any ideas on how to get the matter administration working again?

Connecting 2 Nest Thermostats, Eve Motion, and a Nano Leaf light strip.

Maybe restart Matter AddOn.

Did you by change upgrade Home Assistant beyond 2023.12.2?

Is there a problem with HA beyond 2023.12.2 that could cause this? This has happened to me a few times, and I can’t figure out why. It’s been working solidly for over a month. Then stopped last night at some point. All Matter devices just un-paired. No HA update happened last night… ?

Did you get anywhere with this?
