Anyone else running Victron Cerbo GX with a mix of non-Victron kit? How are you handling the gaps?

Just got my Cerbo GX set up on the boat and it's brilliant for the Victron side of things — BMV-712 state of charge is spot on, MPPT 100/30 data coming through cleanly, everything talking nicely on VE.Direct. But I've got a Fogstar Drift 100Ah LiFePO4 that communicates over its own BMS app, and a Solis inverter that technically has Modbus TCP but I'm struggling to get it to show up properly in VRM. Feels like I'm looking at half a picture most of the time.

I've had a poke around with Node-RED on a Raspberry Pi sitting alongside the Cerbo, pulling in the Solis data and pushing custom MQTT topics to VRM. Got it sort of working — I can see the inverter wattage appearing as a "grid meter" which feels like a bodge, but it's the closest I've managed. Anyone done this more cleanly, or found a better integration path for non-Victron inverters specifically?

Also curious whether anyone's bothered setting up proper alerts — low SOC thresholds, high battery temp warnings etc. — through VRM's alarm rules, or whether you've rolled your own notifications via something like Home Assistant or Telegram bots. I'm wary of adding more complexity but the Cerbo on its own feels a bit passive about flagging problems.

Yeah @CoastalWanderer, boats are where it gets interesting! I'm running a similar mixed setup on my narrowboat — Cerbo handles the Victron kit beautifully but I've got a non-Victron inverter and a couple of older panels on a separate charge controller that are basically invisible to it.

What I've done is run a Raspberry Pi alongside pulling data from the rogue bits via Modbus and MQTT, then pushing it all into a custom Node-RED dashboard. Bit of a faff to set up initially but now I've got proper visibility of everything in one place.

VRM portal is still my go-to for the Victron side remotely, but locally the Pi dashboard fills the gaps nicely.

What non-Victron kit are you trying to wrangle in? Makes a difference what options are realistically available to you.

Mixed setup is exactly where I live with my cabin system. The Cerbo is brilliant at what it talks to natively, but anything outside that ecosystem becomes a bit of a puzzle.

My workaround for the non-Victron bits — specifically my Fogstar Drift batteries — was leaning on the VRM portal's custom widgets and pulling data separately via a Raspberry Pi running Node-RED. Not elegant, but it gives me one dashboard that actually shows the full picture.

The gap I still haven't properly solved is accurate temperature monitoring across multiple battery banks feeding into VRM cleanly. The Cerbo sees what it wants to see.

@DodgyGrafter curious what your narrowboat setup looks like — boats have that extra complication of shore power switching into the mix which I imagine makes the monitoring gaps feel even more pronounced when you're away from the vessel.
