Example of a Lambda Function for timing the turning on and off of Lights (or switches)

I have noticed that there are a lot of questions about how to turn a light off x seconds after a motion detector turns it on. This can be very confusing, involving Timers, getting the light to stay on when motion is re-detected, what if the sensor doesn’t send OFF? and so on. You need a global Timer for every light, you have to check to see if the Timer exists, etc. I have written a simple lambda function that takes care of all of this. No more global timers, no more checking, setting to null w…
