I don't think this is possible. When you shut down your Raspberry Pi, you are basically stopping all processes.
What about some sort of Wake-on-Lan (or similiar) method. Not sure if that is supported by the PoE hat.
Unfortunately WOL is not supported at all on the Pi main board so it was not implemented on the HAT.
Simplest way would be to use a board like the Pi Juice
and have it wake the Pi at regular intervals even if it’s not asleep. It does not stop it going down BUT does get it back for you.
1) Rename or create an alias for the reboot and shutdown commands
2) Investigate if any of the hardware watchdogs will reporter the Pi - not sure of my head as they normally do a reset
3) Manually pull the Ethernet cable at the switch end - risky but saves climbing in the roof or where ever you are putting it.
Edit: Forgot about this post viewtopic.php?f=37&t=140994
- maybe you could mod the circuit to be triggered by an external watchdog?
Need Pi spray - these things are breeding in my house...
