I've made a remote power rig manager, so i can send commands to my pi, that send command to my relay and the magic happens
I can press the power button for soft On/Off, i can pres the reset so the machine shut off and turn on again, or i can press Hard button, for a hard reset if the machine is stuck( it ill hold power for 6 seconds, wait 10 seconds, and them start the machine again

the design is pretty bad , but it works
