I am going to build a house and due to the fact that I have a passion for Home Automation I am considering to add some(a lot) extra wiring, but some comments and price indications would be great.
I would like to wire all my lights back to the DB. One circuit per room. Then install Relays in the DB to be able to provide control. Instead of thus having Live wires in light switches I run low voltage cat5 cable(one per light switch box) to the light switches, all terminating in a seperate low voltage DB. The low voltage DB then connects to 220V DB to control relays(12V) via a controller.
I would also pre-wire my network points.
Any comments on the price for extra cable, labour and conduit would be great. 3 bedroom double story, 250sqm.
I know it is a very open question, but maybe a % estimate would be great. e.g. 100% more.
What make DIN mountable relays are advisable?
Thanks in advance
