Temperature reading drops to 0C/32F after period of time

[andypiper]

Creating a new issue for this apparent bug.

Has the bug [been fixed] where over a long period of time, the temperature reading goes to 32 degrees (F), and stays there?

I believe I saw this happen where the temperature display became 0C overnight, one time. Simply restarting the board resolved the issue. I need to do more monitoring (possibly will track MQTT messages to try to pinpoint a consistent period of time).

I guess this could be some kind of memory issue, or possibly a bug with the sensor module itself? Will keep an eye on it.
