Back in July, I turned off the motion sensor on a hotel thermostat so that it would cease cycling the A/C and waking me up whenever I stopped moving (which one does when one falls asleep).
Now I'm at a Hilton Garden Inn outside Washington and the thermostat may have a motion sensor, but it's not clear. It has an all-or-nothing understanding of how to heat or cool a room, and it's paired with a very loud HVAC unit.
Fitbit says I got more than 6 hours of sleep last night because the Fitbit device doesn't sense when something wakes you up and you lie still, silently curse mechanical engineers everywhere, without actually moving your arm. (It did log 15 "restless" incidents spaced at regular intervals, however.)
