According to the docs, OpenHardwareMonitor should publish 2 class (Hardware and Sensor) to the WMI but I cannot see any. I OpenHardwareMonitor has full read & write access to WMI so I'm not sure what's wrong. Am I even going about it the right way and should you be able to see those classes?
EDIT
Probably a cause of the same problem but when attempting to use the namespace OpenHardwareMonitor in my c# app
using OpenHardwareMonitor;
it does not recognise it
I forgot to add the .dll to my resources. Rookie error
