I probably have 15 motion sensors inside and outside my house. What I learned, is not to put them in rooms where you're going to hold still. Studies, Offices, Bedrooms, etc., They go off to quickly and you 1) either end up waiving your arms like you want the airplane to land, or 2) when something moves and you're trying to sleep, for example, it goes on.

They also have timers on them, so you can set the bathroom for 10 minutes, but the shower for 15 — or something like that. Mine are set that way for some time or another.

When I first got electricity in my house, I had the hall light put on a motion sensor. Previously to that, I just opened my cell phone to navigate through the construction. The 1st time I walked into the hall, the light went on, I had a heart attack, I threw my phone and screamed. I looked around to make certain there weren't any strangers in the house watching, grabbed my phone and told my electrician friend that there was too much light in my house. He had to come take this out. He laughed so hard I think he peed.

These things can save you a TON of money. I'm here to tell 'ya.

I was also thinking about the hallway. That gets left on all the time too. Hmmm, there are a bunch of rooms around the house that might benefit from a little automation.
