Once in awhile I will throw the sensor unit on mine into the basement freezer to see if I can trick the wife into thinking its minus 10 out.
About 15 years ago I recorded an hour of the weather channel as a major mid 2000s blizzard was about to hit. On April fools day I let the recording play in the living room and left to see what would happen…
Last summer we got some new mini split A/C units with remote thermostadts. I threw one of those in the freezer for awhile and then took a picture of the 41 degree reading on it and sent it to my wife at work to show her how good the units cooled the house.
None got a laugh and now that I am thinking about it, I didn’t get any afterwards either. Try something else next time I guess…
