Hi, I have several Fibaro switches and dimmers. In my living room, when everything is turned off, one of the dimmers keeps reporting power usage of 0.6W.  
Anybody got a clue how that could happen? Could it be that there is some current spilling onto the blue wire?

The dimmers always use a bit of power themselves to be able to function (so it always spills some current, through the brown wire). By default, it doesn’t report this though:

Perhaps self-measurement is active for this particular dimmer?

I think, actually all perma powered devices have that. My Fibaro wallplugs also have this option.
