I test extensively with lightning devices.
on / off
And the more you do simultaniously, the higher probability of crashes.
I suspect something is not good in 351
Also with dimmable devices, I can turn off, turn on, turn on 50%, turn off, but never turn on again to 100%, turn on will only go towards the latest dimmed session your had.
Also there is device template in linuxmce called PLCBUS, #1920, and that already has the ruby code implemtented, but if I copy paste it to my version of the plcbus, it doesn't work.
