I have an automated light in my guest bathroom. Someone walks in, it turns on immediately. When someone walks out the light stays on for about 4 minutes before it goes off.
For some reason, the light freaks everyone out. There are sinks that turn on without being touched, toilets that flush hands free when you walk away, and even toilet paper dispensers that roll out (a somewhat limited) amount of tissue when you need it.
Most people adjust to it coming on, but when they exit the bathroom they usually tell me, “man, I tried to shut the light off, but I couldn’t”. Then I explain it’s all automated, blah, blah. And they ask, “If it comes on as soon as I walk in, why doesn’t it shut off as soon as I leave”?
This is almost always what they ask. I explain there are a couple reasons – I don’t want it shutting off on them while they are still in there (it detects movement – but if your “movement” take a long time, the light could just figure you left, and shut itself off). I also noted that when I have people over, when one person goes to the restroom it starts a dominoes effect. Usually 3-4 people follow in short order. So it’s cheaper to keep the light on the extra four minutes than to keep turning it on and off.
It sucks that homes aren’t more automated. It sucks that it is so rare it still freaks people out. Even tech people.
The switch costs about $25.00 and replaces your current switch. Isn’t there a room in your house that always seems to have the light left on?
