*** Issue of the topic**
After inclusion of Wall Plugs by OH scan-function and generating channels for switch and 3 for power & energy, I got data for the electrical related items, but the switching item is not working (see log file). When use the in the item-view I can see in the log-file only: Switch received command ON & Switch predicted to become ON, but for OFF topic and the actual electrical data!

So the electrical items are working but not the switch item!

Why? Are there any ideas, what I did wrong?
