My SmarThings hub is updated and now includes the Aeotec Home Energy Meter Gen5. I have contingency

So far I haven not discovered any explanation or instruction how the Aeotec HEM provides any useful information. The Smartthings app displays Right Now ON and four selections ON OF a broken circle with an arrow when touched does nothing. There is a Slider selection when touched blue scale zero thru 99, but no explanation given as to meaning.

Any help here is appreciated?
