I have a Display Dash and would like to display the main battery voltage. The battery used to power the dash. From reading the spec sheet for this display, it implies it has an internal sensor that reads the battery voltage. I understand I can get a separate sensor to monitor a different battery.

I have 6 sensors on vnet and they work fine. I don’t see anything in the Datalink. We have another display with the same issue.

How do I get the display to show voltage without having to buy a 230-VM-BVOLT?
