for a recent demo with grafana i started to implement a powershell module to easily run redfish tasks fromom powershell with idrac ( as the microsoft odata module was not really helpful) if somebody want´s to try the modules , see here github.com/.../idrac4redfish
Thanks @sddc_guy. I'll take a look at it. It looks useful for folks who want to use PS + Redfish. Thanks for sharing!
