I realize I'm a bit late to the party, but GL-iNet does this. They run OpenWRT, too! PoE support can be hit or miss, but being able to truly own my devices without compromising on features is amazing.

You probably want something like [0], which has PoE support and an optional Cloud connection. You can roll your own automation with (e.g.) SSH access since they are just Linux machines.
