I just setup a new system and have two different Solar Arrays and controllers connected to one battery system. In my previous setup the two charge-controllers would synchronize settings (absorption, float..etc), but in my new system they are not doing that. If I change the float value on one, it does not update on the other.
I have verified they are both on the same Bluetooth network.
They are running different firmware but they are both up-to-date according to VRM and the app.
