Custom vrm

hi i have a small intalation all 24v no inverters installed, how i can custom the vrm screen to have reading of direct load on CC

The Dashboard screen is not customisable.

You can use VRM but will need to use shunts or and energy meters
I have a setup where no Victron inverters, using VM meter to collect grid data and shunt to understand battery state.
Going to get PV,AC,Battery values from non-VIctron inverters and use mqtt-*-vrm addons from GitHub to let VRM knows more about devices.
But this requires NodeRed, MQTT, linux, python, etc - knowledge.
