DC consumption not logging on VRM?

I have just set up a Raspberry Pi running Venus OS

System: 2x 75/15s + Pi / 7s Lithium NMC / DC only setup with all loads via the load outputs.

So the VRM dashboard shows 'live' consumption at last update, the advanced widget 'System Overview - DC system' does a good job of allowing me to see watts used at any point in time.

Load out data from the MPPTs clearly exists. Why then is there no DC consumption logged on the dashboard like solar power produced?

Hi @TTbb

there is, but not as 'DC power' that is only available with a battery monitor.

Hi @Daniël thank you for the reply . I am not so interested monitoring the individual outputs at any point in time, although its useful and nice. Totals over a time period in watts is what i am after.

If all the data is already available and clearly it is because consumed watts are logged within the controller history, live consumed watts are being shown in the VRM dashboard. 'System Overview - DC system' can be used to track back what was used at any point in time. Why is a battery monitor needed just to log this data to present it like the PV watts generated? That seems to make no logical sense!

I thought i would give the VRM a go and set up the Pi because the MPPTs are functionally compromised by the lack of an internal clock. Without a new day starting at a consistent set time and a useful time such as midnight the logging in history is not really that useful.
