Cerbo not Recognising Battery

[adamhratcliffe]

Hello,

I had a RPi based Cerbo system which I have upgraded to the actual Cerbo however I am having some issues setting it up.

I have Renogy Lithium Battieres connected via RS485 cables and my pi Cerbo was able to read them via the https://github.com/Louisvdw/dbus-serialbattery

I have installed the driver on my Cerbo but cannot get them to read the batteries. As a result, I cannot charge them via MPPT presently because the Cerbo doesn't detect a BMS.

I have tried troubleshooting but with no joy. Here is the error log via SSH
