I see tables, I am exited. But I can't make sense of what anything is? I know COP, but what is Training, what is Source? MID seems to be a kind of sensor? Some of the table headers have a tool tip explaining things, but are the ones that aren't the most needed. Also, some about page about what the table aggregates and how it gets there? Seems to be some kind of aggregator for information gathered from an appliances called "emonHub" which is a rPi that gathers data from an assortment of other devices. There are some jargon that you have to parse, ("supply" means the electric cables that "supply" your heat pump) to understand what's going on.

The best guide I could find is buried all the way down of the documentation https://docs.openenergymonitor.org/applications/heatpump.htm...

That's it.
