We live on a boat and I have a CCGX connected to a BMV-712, Quattros’ and Smart MPPT. I connect to the CCGX with my MacBook Pro via GSM Wifi. All works great with VictronConnect and with the VRM Portal. I recently discovered Victron-Docker-Grafana and I have got this working with live data over a GSM Wifi - works great.
I want to display historical data (instead of live data) on the same Grafana Dashboard using the Backlog file created by the CCGX and VRM. Ideally, I would like to discard the VRM Portal altogether and use the Backlog data (Sqlite3?) with Grafana, but I cannot work out how to create the Backlog file without sending it to the VRM Portal (it is erased when the CCGX connects to the internet).
Can I display historical data from the Backlog file on the Grafana Dashboard (and if so, how)? Can anyone suggest how I get over my communications problem, but continuing to use a Wifi solution?
