I use PoE to power my hubs as well as most of my UniFi network hardware. Thus, I can cycle power to a specific port should the need arise. All of the UniFi hardware is powered by a Cyberpower UPS.
Note Well: If anyone wants to use a PoE splitter to power their Hubitat hub, please review the following thread to see PoE splitter devices that have been tested to work reliably with the HE hubs.
