Should I upgrade to SmartSolar MPPT? (corrected)

Hello, I have an Airstream with BlueSolar MPPT + MPPT Control. If I add the Cerbo GX (which replaces the mppt controller) + a Smart Shunt, is there any benefit to upgrading from BlueSolar to SmartSolar if all devices are connected to the Cerbo via VE.Direct cables?

In other words can the smart shunt & blue solar share info via the cerbo or do they still need the ve smart network over bluetooth to share info?

Data passed between devices via VE.Direct through a Venus Device (Cerbo for example) has priority over bluetooth data. So there is little motivation to upgrade your Blue Solar to Smart Solar unless you also want data on your phone/tablet via bluetooth.

Cerbo won't make data available to bluetooth devices but phones/tablets can connect to it's screen via Wi-Fi.

Awesome. Ty for confirming. I also verified the Blue Solar is available remotely via the Cerbo! Do you know how I can verify MPPT is pulling measurements from the smart shunt?

Here are some screenshots of it working as described:screenshot-20210413-233811.png

Enable DVCC in Cerbo settings and select shared voltage sense, shared temperature sense. and shared current sense.

You can also set a system wide charge current limit for your battery bank. Cerbo will insure the combined current of all charging currents does not exceed this value.

From Smart Solar to Blue Solar would be a downgrade.

Smartnetwork is still used and Bluetooth is still a useful way to quickly access the settings.

Thanks for the clarification. I got them mixed up. I would be going from bluesolar ==> smartsolar. (i updated my post).

So if Im understanding you correctly, the SmartShunt and MPPT device require ve Smart Network via bluetooth and cannot utilize the ve.Direct connection instead? I agree on the usefulness of quick access to MPTT settings, but my understand was the Cerbo can now allow remote access to the device. Hopefully I have all that correct.

Thanks again for the correction and responding!
