Will extra meters improve DESS?

I’ve also observed that EV charging throws off the consumption forecast, and apparently adding an extra meter is supposed to help:

I did install an extra VM3 meter 2 weeks ago, just to measure the EV charger, and I think it’s helping. However, I’m still waiting a couple more weeks for the “old” data to filter out (I think it takes 4 weeks, if I recall correctly?).

I don’t know if there are different models for heatpumps, etc.
