I do not assign the trade separately and do not do it myself either, so I have no influence on the executing company... I only know an electrician journeyman and no master electrician, unfortunately that is not enough for acceptance, otherwise I would have done it differently...
Visiting on site would be ideal Maybe internet help will be enough
Currently I am really considering already controlling the roller shutters via KNX and preparing the rest a bit:
For that I only need (I took the prices from MDT):
- Bus power supply ~ €160
- 2x 8-fold shutter actuators ~ €460
- 1x 16-fold binary input ~ €230
- IP gateway €170
- EIB cables in switches, windows, doors, lamp outlets, possibly sockets
- Star-shaped wiring for everything that will be switchable in the future
You can’t save on pushbuttons/switches, conventional ones will continue to be used. But at least you don’t need KNX pushbuttons if you have a binary input – correct?
Have I forgotten anything important to get it running like this?
