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?

Haha of course it s going to be conduit. But its what to put in it. Just 230v ac or add 12v dc or POE or both.

Well you definitely don't want to put the power cables in the same conduit with the data cables (PoE being the exception). Run two conduits (one for power, one for data) separated by the distance specified by your local electrical code (probably at least a foot or so, and wider is better). If the conduit is metallic, then the spacing can be less.

In those conduits, run:

The wires you actually know you need right now, and
A pull string.

Yeah .. Definitely will put conduits in .

Don’t mix low voltage DC with AC :)

Yeah separate conduit for AC and DC goes without saying.
