Ok.
But now I saw that the devices that had the alternative ”what is plugged in” was the ”main” device (the one that controls both channels) on Dual Nano switch (ZW140).
Dual Nano switch (ZW132) with energy meter does not have that alternative.
But for zw140 it doesn’t matter if I set ”fan” as plugged in device (on the ”main” device”, the separate devices for channel 1 and two does not have that option). The separate devices for the separate channels still shows as lights.
So in case I would try to change this, if still possible, I need some guidance for how to change class on the separate channel devices on the dual nano switch.
