Like Fantic says, Green is power hereDRuw wrote:@j.hoekstra: Dude what a mess.... fire you electrician.... this is as far as I (not an expert) can tell not according dutch building regulations...
In the Netherlands, we also have a box in the ceiling with the neutral (blue) and the switchwire (black). The power wire (brown) ends at the switch and goes to black after the switch.
So its not possible (I think!) to connect the fibaro there since you dont have the power wire there... either way, you have to pull a power wire to the ceiling box and install the fibaro there or pull the neutral to the switchbox....![]()

Thanks, I thought so already, now I need to go to a DIY-shop to get some install-wire and 'lasdoppen ' which can contain 7*2.5^2 :/Fantic wrote:Don't worry, these are just the old colors used untill the 70's, there are still around in many older installations. these are the colors and their functions:
As far as I can tell the fibaro will then be able to be used as intermediary switch.
