I don’t know if this is a bug or something I have configured incorrectly and I have never seen this before. Running 10.20i. The uploaded html shows my minimum temperature to be a cool 1832.0 degrees F and my maximum temperature to be -148.0 degrees F.
This happened at midnight and fixed itself as 12:10 (second update after midnight). Not a big deal, but funny. I can not remember if I have looked at if at midnight before when it resets to the next day so I don’t know if this happens all the time.
