i tried to clean the cache already.

Possible Solution

no idea

Steps to Reproduce (for Bugs)

1. update a working 3EM configuration to M6 bundle

Context

In the beginning the issue was only on 1 item "WPEnergiemessungDeviceAccumulatedWatts" that did not update.
I thought is may be an issue with the cache. After cleaning the cache all items of the 3EM did not update anymore.

@markus7017 : no chance you have a look before OH3.4 is released?

[stefanheijnen]

Last night I'd also upgrade to 3.4.0 RC1 and have the same issue. Seems like only the device channel is there. Meter1, meter2 and meter3 are gone.

Top part is before the update, below is the channels available after the update.

I removed the relay output from the item definition.
Still the same error.
