HEM V1cs Stopped Working

All my HEM V1's stopped working. I've removed and repaired, but get nothing in the logs. I had one that hasn't been plugged in for a few years and tried that, still nothing.

Has something basic with z-wave changed that would break these?

My HEM v1 is working just fine, do you get the rapid flashing of the device LED when including it after an exclude?

Mine stopped sending the average power data earlier this year. I did a Z-Wave repair and it started working again. Not sure what happened.

I don't recall, I'll try again. I've paired these so many times, never had an issue.

Repair did nothing.
