Hi folks, hi victron staff,
i try to use the VRM-API (latest V. 0.3.11 and Venus-OS 3.72) with Node Red. Connectivity and data retrieval work perfectly, but some data collection and responses are confusing and incomprehensible. In particular, the use of the API types “Installations” and “Installation stats” with the attributes “Consumption” and “Total kWh” generates data without meaningful mapping. The data values are approximately 1.6 times larger than in VRM itself. In my opinion, the node VRM-API itself is fine, but the API values are wrong. When using the “verbose” option of the node, the entire syntax makes sense and the correct time window is retrieved. So i get 13 records of month and range of 1 year for “Total kWh” and 7 records for “consumption”. This is okay and expected but the values, as i mentioned before, not.
I also tried other tests and found that using the attribute “Dynamic ESS” retrieves a value named total_consumption with the right value.
Any thoughts or ideas? Maybe Dirk-Jan?
Thanks Ottmar
