Hi,
I have a BMW i3 and have noticed that over time the SOCMAX (State of Charge Maximum) reduces over time, I have a node JS app that checks once a week to get the SOCMAX so I can log the battery degradation over time, It would be great if the SOCMAX could be added as a senors to Home Assitant (then I can log it). In the JSON file from BMW it can be found in the {Navigation:} part, in the same place that you pull SOC from.
