Just a heads up,
we can now control services like the hyperion one via scripts during standby/resume…
I just stop/start it via subprocess like so:
/home/osmc/.kodi/userdata/wake.py
import subprocess
subprocess.call(["systemctl", "start", "hyperion"])
/home/osmc/.kodi/userdata/standby.py
import subprocess
subprocess.call(["systemctl", "stop", "hyperion"])
I actually control 3 hyperion instances just copy/paste the .call line and adjust 
cheers
