Inverter entities have gone missing

Hello, I have an ECU-R (2160), and after upgrading from 2.72 to 2.8.1, all of my inverter entities have disappeared?

They were working fine previously.

They might have been cloned, so for each entity there is a -1 entity created (like sensor.ecu_{ECU-ID}_current_power becomes sensor.ecu_{ECU-ID}_current_power-1). Not sure under which circumstances this is happening. How exactly did you perform the upgrade?

The best thing to do is remove the integration: Settings > Devices & Services > Select the "APsystems ECU Reader" integration and select Delete from the overflow menu.

Restart HA go back to Settings > Devices & Services and select +Add integration and re-add the integration. You should now have all the original entities back including history.

Thanks, that worked, and my history is still there.

I had just upgraded from the UI's Settings menu. I may have upgraded (then uninstalled) the former APsystems PV solar ECU integration as well at the same time, which had already been disabled previously. Could that perhaps have removed my entities erroneously?

When I initially installed the new ECU Reader, it did add "_2" to my previous entity names, so I just updated my settings and things worked fine. But when I came here with my question last night after updating (and removing the former integration, I guess?), all the entities were just "Unavailable" (no new entities had been added when I looked under Developer tools > States).
