Wake On LAN is supported by Hubitat (eg. app here), but the PS4 doesn't support WoL packets.
The PS app can wake the console from standby/Rest mode, but you can't get it to Rest mode from total power off without being present (to either press the power button on the console, or PS button on a controller).
So you'll have to leave the PS4 in Rest mode with power on all the time to be able to remote play
