Controlling Lights and Music with voice control

I've been playing around with controlling my home with Amazons Alexa.  I really like the idea of voice control for lights, air-con, TV and turning my music system on and off.

I'm really enjoying it - my wife is just about getting the hang of it but the kids love it and spend half their time trying to get Alexa to say silly stuff or do their homework for them.

Here's a video of it working.

It's very basic at the moment, I can turn on and off or dim all the lights in my home, turn on and off my music system and change the colour of certain bulbs.  Also turns on and off my TV and media centre.

I will look to expand it later, add extra Sonos control for additional zones and skip songs, adjust volume etc...
