I’ve got two wireless AP’s installed in the ceiling (one downstairs, one upstairs).
Both powered via PoE. The one downstairs have stopped working. However, after disconnecting it, I’ve realised that the one upstairs is adequate for the entire house.
So I’ve got a spare Ethernet cable (PoE powered) hanging from the ceiling downstairs.
Are there PoE lights available? Or should I use it for something else?
I’ve only found one PoE light option available (Ubiquiti square shaped smart lighting).
Anything at a lower price point, ideally with other colours (not only white)?
It’s sort of a fun thing to have, as we already have LED ceiling lights downstairs.

Maybe a POE splitter plus a 12V light? You'd struggle to find something in RGB though, and not sure how you'd switch it.

It's tempting to use it if you need a light. If you go PoE you could try a splitter? Most lights are probably 12v so make sure your splitter is for this voltage. You could always use the cable directly with a seperate power supply - I use Cat6A cable to power relays over 12v from light switches. If you do use the cable directly, be sure you won't cause too much current - those are small conductors. When the electricians tried to wire up my relays they sent the whole current down a single strand of the cat6 cable (like 8A at 12v) - luckily I caught it before it caused any dramas.

Thanks. I think this is the one that I mentioned in my first post.
Is this Alexa compatible? Doesn’t mention it.

I should have mentioned this in my first post. Alexa compatibility is important.
Would be cool if it had lots of colours too (not just white).

Thanks to you and @zeon for this suggestion.
I want it to be smart light and Alexa compatible.
Never even heard if a PoE splitter (I’m a rookie), so need to look into this.

POE 12v converter into one of the many 12v led strip controllers would get you something controllable by alexa/google

Why have I got this extra ‘thing’ hanging from the ceiling?
I’m talking about the extra cable plugged into a block (not the Ethernet cable, which I had plugged into the wireless access point).

Because that is the end of the solid in wall cable, and has a socket on it, then a patch cable which has had its excess stuffed up the same hole.

OK, so the wall cable couldn’t go straight into the end point?
Sorry, just trying to understand the idea behind it.

Yea its solid vs stranded cable - I know it looks crazy but the way it is done is correct.

Wouldn't it be more logical to think that cable run is faulty than AP. You need to test the cable run.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

Not sure if any of these are available here : https://youtu.be/8TfNy5o-4O4

Else you might have to build something if that’s your jam. Mitre 10 and bunnings have their own ranges of smart stuff, but I haven’t investigated panels, nor your Alexa compatibility

This. Particularly with those sharp bends in the cable. May just have pulled a conductor out of that punch down block.

Thanks, is there an easy way to test this?
