Best way to setup alarm for low battery and feed GPS location into VRM?

Hi there,

I am using a Cerbo GX, MutiPlus, BMV-712 and SmartSolar charger combination and was wondering what the best method would be to setup those two things:

- Create an alarm, that notifies me, when the battery runs low (e.g. we have 200Ah, receive a notification when like 70Ah are reached)

- Is it possible to feed the GPS position into the VRM from a different source somehow? We have a separate GPS solution already in place and I want to avoid installing the USB GPS dongle for the Cerbo

Thank you,

Christian
