I have a switch in my loft and garage, both of witch i have to find in the dark to turn on. It would be nice to switch them on via google home before entering either.

The amount of times i have to constantly go around the house and turn lights off after the wife has been there. Be nice just to go to bed and say google turn all lights off.

When the wife is coming home first and would like to have the lights and heating on as she comes into the house.

When you just cant be bothered to get of the sofa when a good movie is on. Loads of reasons i'd like to do it. Just because we get up and do all these ourselves at the minute doesn't mean theres no practical uses for them. My home is becoming more and more automated and id love all light switches to be wifi.
