Anyone know what these are?

Hi All,
I've noticed a couple of locations in our new Fuzion 414 where these small (roughly the size of a quarter) diampnd shaped plastic pieces are mounted on the wall. One behind the door to the master bedroom and one above the sink in the garage for example. Can anyone tell me what these are?

Thanks in advance!
Randy

Remote temp sensors. You have a multi zone thermostat and those report the temp in whatever zone is designated for that area of the trailer.

Ahhh! Makes sense... The multi zone feature was new to us as well. The old camper had multiple thermostats to control each AC unit.
Thank you for the education!
