Home automation with Z-Wave, Home-Assistant, Aeon Multisensor, HUE lights, and a Raspberry Pi 2. I think of stuff like this all the time but the dog would definitely trip the motion sensors, and I work from home quite a bit. For years I've had a table lamp just on a timer so there's always light when I need it in the living room (and it's an LED bulb so it doesn't take much electricity). Still trying to find my use-case...
