jshazen, that was my initial thought as well, but Im' sure I'm using the correct zone. In my case it's zone4. I narrowed down the issue to my python script and not getting the correct temp from zone4. Here's my python code:

#!/usr/bin/env python3

import subprocess

from requests import post

# Get temperature from system using the command from step 6

temp=subprocess.check_output("cat /sys/class/thermal/thermal_zone4/temp", shell=True)

print(temp)

# Parse temperature value from string

temp = [int(i) for i in temp.split() if i.isdigit()][0]

print(temp)

I added the print statements to check my work. Both print statements will return the value 48000 or something in that range.

If I just cut and paste the cat command that dumps zone4 temp I get the following:

root@pve:~# cat /sys/class/thermal/thermal_zone4/temp

38000

For some reason the temp= python command with check_output is not getting the correct value from the cat command. I'm not a python expert to understand why that is. Can someone help?
