Matter smart-plugs losing Energy reporting capability

Since I updated to v2026.1.0 about half of my matter compatible Tapo (P110M) smart plugs are saying they have no energy data to offer. The other half are still providing energy readings as they have been for some time.

I’ve restarted both HA and the plugs in question with no change in behaviour.

All my Tapo plugs are running firmware v1.3.0 with v1.0 hardware.

Since not all are impacted, it seems unlikely its related to the HA update - but I’ve run out of ideas. Any suggestions?

Many thanks.

Has nobody else seen this behaviour?
