I am working on the final wiring layout for my mums new build home. It will likely use Fibaro’s throughout as here in the UK the options for smart switches are limited and not very customisable. There will be a LOT of lights and switches, it’s a very big house!
Rather than trying to squeeze the modules behind each switch, which isn’t going to be possible in the back boxes for multi gang switches, I am planning to star wire all the lights and switches to central hubs (one hub per floor)
The load wires will be fine over the expected distances, but I’m not sure about the low voltage switch wires… can any electricians out there advise on the expected current drop over longer runs, and what the max cable length is likely to be? We will be using standard 2.5mm wire cores to enable conversion to other systems / dumbifying in the future. I’m not sure what the switch wire voltage is on the Fibaros, but I know it’s low (will test over the weekend and update this post).
Worse case scenario I can add more wiring hubs to decrease the longer cable runs.
Also, as the wiring hubs need to be safe and tidy, does anyone know of any din-rail mounted dimmers, comparable to Fibaro capabilities (or din adaptors for the Fibaros).
