5 devices for 1 Fibaro wall plug?

[modular]

Hi i have a question about the fibaro wall plug. It works flawless, but i noticed after includeding the device. I had 5 devices:
- 2 Power Meters giving 0
- 2 Power Meters giving output(both the same and seem ok)
- 1 switch(works perfect)

Now i expected 2 devices 1 Power Meter and 1 switch. Why do i have 5 devices and is it possible to remove to devices that seem to be useless?

Just leave them as unused in the device table. That's about the only thing I hate about Z-wave.
In my case I only use 118 devices of the 232 devices listed in the table.
You can remove them, but they will probably be recreated if you don't disable power reporting.
