I've done a quick video of my Movie theatre command.. Turns off a bunch of wemo switched lights one by one, changes the Hue bulb scene, changes the colour of an LED strip & turns on some LED candles. Created using a horrifically complicated blend of Alexa, Smart things, IFTTT, android, tasker, and harmony. Love tinkering though.
