Here the EM24 Grid Meter is connected with Role "Grid Meter" and shows up ok on the Dashboard as long as Multiplus is working.
As soon as Multiplus is switched OFF, dashboard switches to "AC Input" and shows no values at all.
All that while the console still shows the Grid Meter Values, which in turn show up without interruption in the Graphs under VRM "Advanced".
Is the empty display intended? The EM24 Grid Meter is obviously still available and does send valid measurements.
