Cerbo GX - Ve Direct only to MPPT, no cable to SmartSHunt. Possile to have Battery Charge?

I've an installation with 1 MPPT Solar 100/20 and 1 SmartShunt connected to Lifepo4 Battery.
Actually I've Connected MPPT to the SmartShunt with VE Smart Network over Bluetooth.
I want to add a Cerbo GX to read bettery status over VRM but I can't connect both MPPT and SShut using ve direct cable due to the distance.
Only 1 device can be connected to the cerbo between MPPT and SShunt.
I was thinking if it's possible to have a mixed scenario like this:

Cerbo GX -> Ve Direct -> MPPT Solar
SShunt -> Ve Smart Net -> MPPT

Can I receive the battery charge % and voltage on Cerbo from MPPT?
Is the Shunt status value passed to MPPT over Ve Smart Net compatible with Cerbo GX connected only to MPPT with Ve Direct?

Alternatively I can connect the SShunt to the Cerbo installing it near the battery but in this scenario I think I'll lose the MPPT PV statistics.

thanks in advance for the help

No, data on the Cerbo is only possible via wired connection, so you'll need to connect both the SmartShunt and the MPPT to the Cerbo via VE.Direct.

That said, a couple points:

1. VE.Direct cables are available in up to 10m length, which is usually long enough for most installations;

2. If you need a longer connection than that, you can always just use a VE.Direct USB Interface (https://www.victronenergy.com/accessories/ve-direct-to-usb-interface), and a high-quality powered USB hub to connect it to, then run the USB hub's connection back to the Cerbo - this should be able to get you up to around 30m or so of connection range.

In addition, it is not advised (possibly improper) to have both a wired network and a smart network active on the same system.

Yes. Not supported and we see quite a few problems reported here when people try it without realising.
