It would be great to have a more intuitive way to monitor energy usage.
For example I have a lot of plugs which are reporting currently used energy and a shelly em for whole house monitoring.
But it is hard to visualize this in HA.
My request is to define a standard for energy monitoring and as second request to visualize the data in a predefined dashboard.
Ideas: Trends, Pie Chart, degree of self-sufficiency for PV, Comparison with previous periods
A standard would be to have a energy usage variable for each device which can be updated by the device itself or set as constant if no energy is reported.
In my opinion this is one of the most usefull outcomes of a smart home - get to know where you spend energy and to reduce my carbon footprint based on that knowledge.
