3 Aeotec Smart Switch 6 devices suddenly stopped reporting state

Today I found that my 3 Aeotec stopped reporting state when they are turned on/off during automations.

I have a heater on one and a refrigerator on an other and one has nothing currently plugged in.
All three no longer change state in the UI when I send switch.turn_on/off service events.

The switches work but their state is not reflected. This is breaking a lot of my automation which checks current state to report devices left on, etc

Anyone know if something changed in version 0.80 that might cause this?
