only a short question:
Is there a version of BMV-Reader, which can directly run on a raspi?
There's VenusOS you can install on a Pi so you get the full Victron GX stuff. (https://github.com/victronenergy/venus/wiki/raspberrypi-install-venus-image).
Depending how much you want to play you could also pipe the data into InfluxDB and then use Grafana to display. (I'm planning on this, but I use my Pi for more "home" automation stuff).
