I am rapidly considering it more and more...
Oh yeah, I forgot my requirement for passive cooling due to the fact it will basically live in a bedroom cupboard :)
I'm only actually using one thing powered by PoE at the moment (Unifi access point). I do plan to add another in due course but it's the sheer number of mains sockets required otherwise!
Setup without PoE would eventually be:
- Openreach modem
- Unifi USG
- Switch (TBC)
- Hue bridge
- Tado bridge
- DECT/VOIP base station
- Raspberry Pi running home assistant
- Raspberry Pi feeding ADSBexchange
- Raspberry Pi running Ubiquiti controller
- PoE injector for UAP 1
- PoE injector for UAP 2
I was planning on using two 6 gang surge-protected extension leads (one was never going to be enough) and I will have a 2 gang socket to plug these into, so I'll have 12 sockets. One spare and I've probably forgotten something!
The extension leads do have 2 USB sockets on each but only 2.1A across the two sockets, and I already know from personal experience the Tado bridge doesn't like not being plugged into it's mains USB adaptor and Raspberry Pis are apparently fussy about power too.
I could run the Pis off PoE though which with two UAPs running on PoE and a PoE splitter for the Tado bridge would save me 6 plug sockets, so I could lose a whole extension lead, have the option of running other stuff from PoE and have a spare plug on my 2 gang socket for future growth...

You can run multiple USB things off one power adapter, just make sure it's a decent one. You can run plenty off this for instance

For power I have one of these

Have you considered just using POE injectors as and when you need them?
I'm learning that my requirements (rackmount POE withbpassive cooling) is asking for the moon on a stick.
