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?

Also remember that cables... are just cables. They will take whatever connector you put on thebend of it. So you can use a different one 12v so you dont accidentaly plug things in wrong.

But if you need to pull dc out of POE, you can get thigs that do just that. Search for POE extract or splitter. Many will let you pick wjat voltage to get out of it.

Imo youre better off running cat6 or 6a everywhere (better yet conduit where reasonable) and not running a 2 conductor pair along with your cat cable. Just terminate your cat cable as usb if you dont want to use an extractor.
