Hi, I'd appreciate any expert advice on this;
I'm having my house rewired and keen to get minimise wall warts/power adaptors for the various permanent smart home fixtures that I'm inevitably going to burn cash on over the coming years (i.e. 5V (USB) wall fixtures like NEST thermostats, RING alarm panels etc as well as 12V accessories like doorbells and blind motors).
Is there any practical or regulatory reason I couldn't / shouldn't run 12V feeds back to a central 7A 12V DIN transformer in my CU for blinds and 12v kit (and then use a small step down to 5V where required for permanent USB devices)? I believe the max run will be about 35m so hopefully, voltage loss will be negligible.
I respect this is only what people have done with doorbells for years but didn't want to overengineer if there's a smarter way others are addressing the proliferation of low voltage, permanent tech. I plan to use power-over-ethernet PoE wherever possible for network stuff.
Thanks in advance..
Ben
