Anyone else running Victron Cerbo GX with a mix of non-Victron kit? How are you managing it?

Finally got my Cerbo GX wired up properly last weekend after it sitting in a box for two months. Running it alongside a Renogy 40A MPPT and a Fogstar Drift 200Ah lithium, neither of which talk to Victron's VE.Direct or VE.Can natively. The Multiplus II is singing away beautifully on VRM, but half my system is basically invisible to it.

I've bodged a workaround using a Victron SmartShunt on the battery to at least get SOC and voltage into VRM, which helps a lot. But the Renogy controller is sat there doing its own thing via its own Bluetooth app — no way to pull that data into the Cerbo as far as I can tell without spending another £150+ on a third-party RS485 to USB adapter and hoping someone's written a driver for it.

Has anyone actually cracked a clean integration for non-Victron MPPT data into VRM, or are most of you just running parallel monitoring and accepting the system overview will always have gaps? Curious whether it's worth the hassle or if I should just swap the Renogy out for a Victron 100/30 and be done with it.

@ExTrucker63 familiar situation here. My setup mixes Victron MPPT and inverter/charger with a Fogstar Drift bank — the Fogstar's BMS doesn't communicate natively with the Cerbo obviously, so I'm relying on a Victron BMV-712 shunt for accurate SOC rather than trusting any inferred calculations.

For your Renogy MPPT, worth noting it won't appear on VRM as a proper device — you'll only see its contribution indirectly through the shunt. If that bothers you long-term, a Victron SmartSolar is worth budgeting for, but it's not critical.

The Cerbo's two-wire temperature sensor inputs are useful for monitoring the Fogstar cell temps manually if you want that visibility without full BMS integration.

What assistant relay outputs are you planning to use? That's where I've found the most value integrating non-Victron loads — my garden office climate control runs off those.

Great to see you've got the Cerbo up and running @ExTrucker63! The Renogy MPPT is the trickier one — since it won't communicate directly, I'd suggest picking up a Victron SmartShunt if you haven't already. It won't fix the Renogy's silence, but the shunt gives the Cerbo proper visibility of your overall battery state, which partially compensates. For the Fogstar Drift, check whether yours has the optional BMS Bluetooth — some users have had luck bridging data through third-party Node-RED flows running on a Raspberry Pi alongside the Cerbo, though that's a rabbit hole! Honestly for most practical purposes, the SmartShunt doing the heavy lifting for SOC monitoring is sufficient. The Renogy just shows as a generic PV input effectively. Not perfect, but workable. What firmware version is your Cerbo running? Some earlier versions had quirks worth updating past.
