DESS whats happening here

I keep switching on DESS, but its not really that intelligent, or I have something set up wrong, surely DESS shouldn’t be pulling from the grid when I draw a load, surely that should come from the battery, seems that just under 1/2 is coming from the grid, and the rest is coming from battery/solar

I dont want to be taking any electricity from the grid, the battery is 94% charged and all should be coming from the battery or solar.

So is this just because DESS is still not sufficiently refined to work this out, or do I have some settings wrong.

If I switch off DESS, all consumption comes from the battery and/or solar, nothing from the grid
