Yes, it uses sispmctl (should be an apt-get install sispmctl away, or such)

I have the attached energenie-power script on my raspberry-pi - and other
automated scripts hook into that to control some of my boards.

I'm hoping (in some sort of magical free time) that I could implement a better
solution abstracting this akin to labgrid or such ... but alas - free time is
rare - so I'm still just using this basic bash script - and editing it if I
change the devices connected.

Would be nice to abstract the device names elsewhere somehow. If you have more
of this mystical substance called 'time' please do let me know how you get on :D

Interesting indeed (the ykush)! I hadn't seen that either :D
