Home Wiring (lemmy.ml)

This might be tangential to HomeAssistant but Im currently thinking about a household renovation and one thing I am considering is wiring.

I have some POE devices along with many other that run with a 12v DC supply.

I'm lookin at putting in a relatively straightforward 12v battery UPS with a small solar panel to charge. I probably only have space for 1500W of panels so putting in a whole grid tied solution is overkill. Primarily this is to provide backup as we sometimes lose power.

Networking wise I think I will put RJ45 into each room as we are concrete reinforced construction and so signal quality is an issue.

My query was how feasible it is to run both standard PEO devices and 12v devices (1-2w) all over POE.

I thought the alternative would be to run separate 12v cables with USB connectors at the end into each room as well as Rj45

Is anyone else doing this in their home?

Personally I'd run separate 12VDC cabling instead of pulling out from POE if it's simple to do, but if you get a splitter which will negotiate POE (assuming you don't run some older passive-POE setup) it should work just fine. But note, that POE goes up to 57VDC, so check that you can run your POE switch/injector with 12VDC at all.
