I have a SeeLevel tank system connected via NMEA2000 and because of current limitations in Venus, I'm running a program that separates the 3 tanks reported by SeeLevel into separate dBus objects. I hide the original SeeLevel dBus object which reports all three tanks in rotation (modified QML code). On VRM, there isn't a way to hide this constantly changing tank information so there's always a 4th tank that provides incorrect information.
It would be nice to be able to hide this tank on the VRM dashboard also. I can't think of a way to do this automatically so it would need to be a manual configuration item in VRM.
I realize this problem will go away once Venus code is updated to handle multiple tanks from the same NMEA2000 device.
