This is somewhat related to the home theater thread...
Anyone into home automation? I'm just starting to investigate the tech and possibilities.
With the right gear, you could have a smart house almost as futuristic as Star Trek. You can do things like command the system by voice using Amazon Echo. "Lights on!" Or "Watch Netflix!"
At the very least, you can set things up so when you turn on the A/C via a Nest thermostat, the ceiling fans also turn on. Or at 10:00 PM, when you go to bed, all the lights and ceiling fans get turned off.
Motion sensors add more possibilities, like if you walk into a room and it's after sunset, the lights turn on. As it gets later past sunset, the lights dim.
Minimally, you can replace an existing wall switch with a smart one and add one or more additional switches anywhere you want to create 3-way or 4-way set up. The additional switches talk to the first via wifi.
I'm interested in anyone else's experience. What gear do you use? Does it work well? And so on.
