I have a three phase system with a manually switched battery backup Quattro system that is only one phase. The Quattro is fed directly from the grid and a generator. The VM-3P75CT is connected to all of the loads and measures the energy being used by the loads regardless of the source (three phase grid or generator, and single phase Quattro connected to all three phases on the input). As currently connected, the VM-3P75CT is being used as a load meter, but when in load meter mode it doesn’t show up on the dashboard. If it’s configured as a grid meter, it works correctly most of the time as the Quattro is only used for extended outages, but when the Quattro is working the results are not accurate as the grid meter is apparently added to the Quattro output to show the loads in the dashboard, resulting in a doubled load figure.
What I would like to be able to do is select the AC Load meter as the measurement that shows up as the AC loads on the Cerbo GX and VRM instead of the Quattro. This seems like it should be very simple, and a similar question has been asked here. At the very least it seems like the other question should be addressed so we could see a sub-load on the dashboard.
It should be visible on VRM, just as a widget on the “Advanced” page. That doesn’t work for me as I want it to replace the readings from the Quattro. However there are other users who want to have a separate AC loads box on the main VRM page. I think both of those should be options, especially given the advertising claims that would make a person think it’s possible.
Here’s what it looks like in load meter mode. No data because I changed mine to “Grid Meter” mode which at least works when the power is on, which is most of the time.

I am going to move this over to the VRM beta space because we are putting some work into improving the handling of Energy Meters without Multis/Quattros soon.
It might be some time before it gets responded to again, but it’s on the radar.
