I stayed at a pricey resort in Jamaica for a week that had the air conditioning and all the electricity in the room hooked up to motion sensors. The name was Robot RC 6615 Room Control-SiSNet. Many of the hotel reviews complained about the rooms being so hot and humid and the drinks being warm in the refrigerator when you returned to the room. I hung a mylar balloon (shiny silver helium balloon) that I got at a dollar store from the blade of the ceiling fan. I ran the ceiling fan on low because the balloon was getting caught up if it was run faster. I didn't bother to inflate the balloon. The trick worked. The electricity (fan kept running) and air conditioning stayed on in both of our connecting rooms. But a few tips: during the day the curtains needed to be wide open for this to work, in the evening all 4 of the lights in the room had to be on if you were leaving to watch a show. This system needed to have enough light reflecting off the balloon to work so it wasn't strictly motion. The cleaning lady looked at it one day. I told her it was my daughter's disco ball. She laughed and never took it down so we were comfortable the whole week.
