IOT, Smart Home, Intelligent home; Meaning a lot of connected devices (and power adapters & cables!)
I have been using the Philips Hue system from the very beginning, recently upgraded to the Philips Hue Bridge 2.1 Square-shape bridge (supports Apple HomeKit)

After my last upgrade to the home infrastructure. with the new and improved UniFi Switch PRO 24 PoE I wanted to get the most out of the switch with POE (Power-Over-Ethernet)

I would have loved to see the Philips Hue Bridge with build-in POE, but unfortunately that was not the case of the 2.1 release. Luckily with a bit of creativeness this can be achieved with the correct equipment and cables.

The bridge comes with a regular DC barrel plug adapter

Parts list for the items you will need:

Barrel adapter to USB – NOTE: The V2 bridge barrel is 5.5 x 2.5 mm
Direct link: 5.5 x 2.5 mm DC USB
Moreover, if you buy a barrel adapter to USB, you will be able to use any POE adapter.
Ubiquiti Instant 802.3AF to USB adaptor requires not configuration plug and play!

NOTE: 2 Networking cables will be needed with this solution, 1 for POE, and 1 for the actual device connection.
Additionally, if you do not want to use 2 ports, go for a POE splitter with barrel adapters (802.3af POE splitter with 5 volts DC)
