I've seen this mod XERC 2 XE for an IR remote to power on the console. Is it possible over IP to power on the console? Maybe through a Raspberry Pi Zero or something.

You can also eject and emulate long and short power presses. It also includes a bonus LED Fader feature on the status light. The IR Receiver is included. No support is given for the installation of this item.
