Aggregate Series How to

Hello everybody.
I just bought a Smart Meter Interface from Homematic ip and would like to create an Overview about how much kw/h per day i bought and how much i sold. So as far as I understood, Aggregate Series should get me that data. But whatever I try to create such a chart over the GUI, it doen’t work.
A Line based time series is now problem, but this doen’t cover the per day consumption / production.
Is there any Tutorial or Video how i can crate such a column based Diagram?

This is how my grid looks

This is the Item Configuration

Any Ideas?

I don’t think you can easily get there with just charting. I think you’ll need to create separate Items for your different aggregation timeframes and then chart those. Luckily there’s a rule template on the marketplace that does the calculations for you.

If it doesn’t do everything you need, it’s at least a start you can expand on.

It should work. See here:
