I would whish some kind of Energy Management in Openhab.
Therefore I could image one Energy Management Page which contains following information
-
Solar, Grid, Home Distribution Widget
see also Energy Dashboard - #11 by JamesC -
Energy Consumption Charts whichs shows how much energy from solar or grid (stacked charts)
see also OH3 charts - how to stack values? - #3 by bastian -
Solar Production Charts with solar forecast
-
This Energy Management Page shall have a today/day/week/month/year button.
(At the moment this is also not possible for chart pages, only one of day/week/month/year possible) -
Improved internal handling of energy values in OpenHab.
At the moment you need several rules and items, e.g. calculate meter readings to consumption
rrd4j persistence service can actually not be used as it is persisting on every state change and at least once a minute (consumption values not correctly summed up on chart pages)
Overall most of it is already possible, but only with a lot of effort. A more straight forward approach for energy management would just be great.
