My portable weather clock glitched today. I just switched the LED Shim to display temperature instead of pressure yesterday. So today I tested my temperature code from plus 35 to minus 35. I remarked out the code that pulls the value from the BME680, set t = 35 and did a t = t - 1 each time it reads it. I did find an error in my math but it wasn't what was causing my glitch. It didn't error until the temp went below -27c. Its fixed now anyway. It was an error in my LED Shim code.
It never glitches while I'm watching it so I have no idea why it stops? Going to go test my pressure code next. I also increased the scroll speed to speed things up while I'm testing things. Just have to remeber to slow it back down when I'm done.
Maybe it just doesn't like the cold? Electronics do usually have a working range of temps they recommend you run them in. I'd have to do some Googling to find all the info for all the bits and pieces I have in there.
My barometric pressure code test is running now. It just went from low to mid range. I started at a very low pressure and did a p = p + 1. 22 dots or points per range so it will be a while yet. Has to count up to High then very high.
Will test the humidity code next. Should have done this long ago.

What is its operating temperature? Does it need a heatsink?
The Raspberry Pi is built from commercial chips which are qualified to different temperature ranges; the LAN9514 (LAN9512 on older models with 2 USB ports) is specified by the manufacturers as being qualified from 0°C to 70°C, while the SoC is qualified from -40°C to 85°C. You may well find that the board will work outside those temperatures, but we're not qualifying the board itself to these extremes
Looks like 0c might be the limit and I'm going below that, maybe. I'm not sure what the actual temperature is inside my case? Maybe all I need to do is tape over my air vent holes in the winter and let the heat build up in the case?
All the code checked out OK except my one error with my LED Shim Temperature display. Thats now fixed. Non of this affects the file your running Jack, there is no LED Shim code in yours. By yours I mean the THP.py file I have up on my Onedrive that I believe your using.
It appears the new official keyboard hasn't been released in English US? Not yet anyway. All I'm finding is English UK. To quickly tell which is which look for the @ key. On English US its above the 2, on the UK one its over by the Enter key somewhere. I was wondering why Adafruit didn't have it listed? The Pimoroni and PiHut ones are English UK. Anybody thats buying one should read the description carefully.
