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?

The specs for latest versions of POE go up to 60-100W which is way beyond what I expected. Is that just still running over normal Ethernet or should I be looking for specifically rated stuff?

You can get that kind of power through a Cat6a or Cat7 ethernet cable but a lower spec cable won’t work. here’s an article that talks about the limitations https://sixtytrend.com/can-cat5e-do-poe/

Really useful thanks. Definitely sounds like I will be thinking about the Cable Cat more carefully.

definitely run two cables for each point. nothing beats having a cable be broken somewhere in the walls with no way to repair it.
