Cellular Network Unhealthy

Troubleshooting
17

I flashed the code again - which I had done multiple times last night so a bit confused as it now seems to working. Stupidly I unplugged the power supply to see if that was the issue - which made two changes at once. I should have not done both at once but I did plug power supply back in and it seems to be still working. So perhaps for some reason though it has said the code was flashed successfully it was not.
Here is the code.
To see if it flashed correctly I added a duplicate temperature to send to ThingSpeak to see if it flashed correctly and ThingSpeak is getting the new variable.

I will let this run and increase the interval later in the day to see if it works.

If the Electron is in System.Sleep mode I assume you can not flash code. I have been sending code either near the time it is connecting (flashing green) or put in Safe Mode and re- flash. Is this a correct assumption? When I get this works it will be sitting in a building across town. How do you flash it if not in physical proximity?]
Thanks.

Here is the code…
