Hi Josh,

Thanks for the investigation. Would you mind creating an issue?

I think this has to do with Redfish and the power schema. Upon looking
closer, I think this patch should be reverted, and the fix be applied to 
Redfish to distinguish between power sensors and other types of sensors.

I'd be fine if you created a revert as well if there is an issue to 
point to with your research.
