Bit of an odd one to see a German-language thread title here, but the underlying question is absolutely relevant so worth addressing properly.
For those wondering — the gist of it is whether there's decent Linux support for Victron monitoring, and the short answer is yes, considerably better than most manufacturers actually.
I run a Debian-based machine out at my cabin as a always-on monitoring node, and the VRM portal is entirely browser-based, so that's a non-issue from the start. No Windows dependency whatsoever.
Where it gets more interesting is with VenusOS — Victron's own Linux distribution that runs on the Cerbo GX and also the Raspberry Pi (via the Venus Pi image). The fact that they've open-sourced a fair chunk of it means there's a thriving community of people running custom modifications. I've got MQTT feeds going from my Cerbo into a local InfluxDB/Grafana stack on the same Debian box, which gives me far more granular data than VRM alone.
The VictronConnect app is the weak point — it's officially Android/iOS/Windows/macOS only, and there's no native Linux build. That said, it runs reasonably well under Wine for one-off configuration tasks if you're desperate.
For anyone just starting out with a Smart Battery Sense and a SmartShunt (sounds like that's where the original poster was headed), the Bluetooth pairing via VictronConnect on a phone is perfectly adequate initially. Linux becomes more relevant once you're adding an MPPT and want proper system-wide logging.
Anyone else running a full Linux-based monitoring stack? Curious what data sources others are pulling in beyond the standard Modbus TCP registers.
