I am using BCRobotics driver. I rounded to avoid bunch of decimals. Had to
encode to avoid python3 errors. This works fine for me. I have 4 rpi4's
running and get the temp from all of them.
import math
import subprocess
def round_half_up(n, decimals=0):
multiplier = 10 ** decimals
return math.floor(n*multiplier + 0.5) / multiplier
def get_cpu_temp():
cpu_temp =
subprocess.check_output(["cat","/sys/class/thermal/thermal_zone0/temp"],universal_newlines=True)
encoding = 'utf-8'
cpu_temp = int(cpu_temp)
cpu_temp = cpu_temp/1000
cpu_temp = round_half_up(cpu_temp,0)
return cpu_temp
under def get_readings():
cpu_temp = get_cpu_temp()
data = dict()
data["extraTemp1"] = cpu_temp
return data
