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?

I'm not sure I'm getting the gist of your questions, but as far as POE goes, if the device is designed to accept it, it will work at the negotiated PD voltage without problems, but you need a legit POE injector or switch.

If you're saying there is some "other" 12V power you're planning on running over different Cat6 cables, I don't understand why you'd want to do that.

I was debating running Ethernet and a separate pair of cables for 12DC - Thinking maybe I might need thicker cables for USB-C levels of power and / having separate USB faceplates but looking again I think everything could run on Ethernet and then just decide / change what i put on the end.
