I want to retrieve the temperatures, RAM memory usage, used disk space, and CPU load from my computer. I’m using OpenHardwareMonitor for this, but I’m able to get everything except the temperature. When I execute OpenHardwareMonitor on my computer, the temperatures are displayed, but I can’t retrieve them with Python. Any ideas?

Of all the options I tried, OpenHardwareMonitor was the only one that showed me results.

import clr

file = "OpenHardwareMonitorLib.dll"
clr.AddReference(file)

openhardwaremonitor_sensortypes = [

    "Clock",        # 1
    "Temperature",  # 2

    "Fan",          # 4
    "Flow",         # 5
    "Control",      # 6
