Query: False alarms on cold nights?

When I saw this I thought it might be good to place on my sliding glass door for when we are out. So I installed it and set it overnight the first night. I was wakened at 1am by the blaring alarm, too groggy to realize if there was an intruder or not. I dashed to the door, a sitting duck if there had actually been an intruder. Gladly, not. I reset it and was awakened again at 3am by another false alarm! I can only imagine the 45 degree temperature had something to do with it. It has a little magnet fob that goes next to it, and when the alarm is separated from the fob, the alarm turns on. But two false alarms in one night? I don't care to try it another night.I can't leave a device like this in my home unattended, it could false alarm while I'm away, and actually announce to the neighbors that I'm NOT at home. Into the junk pile, or to the returns desk.
