Anyone else using a Victron Cerbo GX with non-Victron kit — what's actually talking to it properly?

I've had my Cerbo GX running for about four months now and on the whole it's been brilliant for keeping an eye on the whole system from the VRM portal. I've got a Victron Multiplus-II 3kVA and a SmartSolar 100/30 both talking to it over VE.Can and VE.Direct without any bother. The issue is everything else on my setup that I want visibility on.

My bank is four 200Ah lifepo4 cells I built myself with a Daly BMS, and I cannot for the life of me get reliable comms from it to the Cerbo. I've tried the RS485 to USB route and it connects sporadically at best — sometimes it shows up in the device list, sometimes it just vanishes after an hour or two. I've seen people mention the JK BMS is far better supported, and I'm half tempted to swap it out just for that reason. Also got a Renogy 40A DC-DC charger for the alternator side and that obviously doesn't talk to anything.

Has anyone managed to get a Daly talking stably to a Cerbo, or should I just cut my losses? And more broadly — what third-party devices have you actually got showing up cleanly in VRM? Curious whether things like Shelly energy monitors or a Raspberry Pi running something like dbus-serialbattery are worth the faff.

@Frank1999 your post seems to have cut off there — looks like you were mid-sentence about what else you've got connected!

That said, I'll chip in anyway. I'm running a Cerbo GX alongside a Pylontech US3000C battery stack and that integration is rock solid — state of charge, cell voltages, temps, all coming through properly via the CAN bus connection. Genuinely impressed.

Where it gets murkier is with my Solis inverter. Got it talking through a Modbus RS485 adapter but it's a bit temperamental — occasionally drops off the GX Touch display for no obvious reason and needs a restart. Not deal-breaking but worth knowing if you're considering that route.

Curious what solar charge controller you're running — the "Smart" suggests maybe a Victron MPPT? If so you're onto a winner, those talk natively without any faff.
