So 20 hrs later, learned JSON, learned CURL/Scripting. Finally accessed the API, and I have two sites. (Home and 5th wheel). I can access my Home Sites data and most of it is populated for the equipment I own, but the RVs site ID has its name, location, etc but all the data is %2F (empty). YT (Solar Yield, BS, etc. All empty).
Online VRM has all my data so I know its there, am I doing something wrong ? I am accessing via for example SOC of my system: https://vrmapi.victronenergy.com/v2/installations/47494/widgets/Graph?attributeCodes[]=SOC"
Any Ideas, site ID is 47494 incase a tech can take alook.
