VRM release notes: DESS Adjustable consumption, Split consumption categories, Multisite AI

Thank you, I’ll report back when we have the fix.

Hi @Barbara

I think I may have found a small bug. Yesterday (Sunday) I was modifying the forecast for Tuesday to remove a projected EV charge and adjust the base forecast slightly.

Later the same day, I looked at the Tuesday forecast again and noticed the totals were correctly adjusted. However, for a few random hours, the split between “base” and “EV” were incorrect. There should be no EV charge, because I set that to zero for all hours.

So I corrected both again, and checked this morning. Again, the totals are all correct but the split is incorrect for a few random hours (I believe the hours I highlighted here are different than the ones I noticed when checking yesterday).

It looks like those small EV charges are of the same magnitude as they were previously, and the system “pushed” down the base forecast so the totals stay as desired. .

Thank you! Loving the new feature.

EDIT: to prove I’m not going crazy :slight_smile: here’s an example from today. This morning I had adjusted the forecast for Wednesday as follows.

And I just checked again, and it’s showing similar adjusted totals for each hour, but the allocations are different.

Hi!

Happy to hear that you like the feature. I just passed your bug on to the team, so I’m sure that they will look into it and come back with a fix very quickly. :slight_smile:

Hi,

I am investigating this and I wanted to ask you if possible to zero the EV forecast for next days so I can track down this issue further.
Thanks

@Amirreza Sure thing. I just set the EV forecast to zero (and changed base forecast to ~2.5 kWh for those hours).


EDIT:

Hmm, just 2 hours later, you can see the last two hours within the blue SOC forecast showing EV loads again.

Hi @A-P ,

Amirreza found the cause: turns out we allow you to adjust the EV forecast even before we have the auto-generated one. By the time that the auto-generated forecast comes in, it overwrites your adjustment.

We’ll adjust it, so you can only change forecasts generated by the model first. For EV, that’s for 48 hours in the future.

Hi,

We found the bug and have the fix for it, It will go live by the upcoming Monday.

Thanks & have a great day.

Amazing! Thank you both

One small possible UX enhancement…

When editing the forecast, using the pop up dialog where you can enter the values for base/EV/HP, I find myself doing this in bulk at the beginning of the day, for all hours in that day. Currently, I have to click each hourly bar to adjust the values for that individual hour.

I can use the “tab” button on my keyboard to move between the 3 text boxes. It might suggest that if I press “tab” from the EV text box (the last one), it takes me to the next hour.

So then I could adjust the whole day quickly, without having to touch the mouse beyond the initial “click” on the first forecast bar.

Hi,
I will discuss the possibiblity of this enhancement within our team, and let you know.

It can be me, but for me it isn’t clear to which release these release notes apply. Can someone clarify that for me. I’m currently on version 3.72 and I don’t see any of these changes, except that I can adjust the consumption forecast. But I don’t see a split capability in roles for heatpump or EV in combination with virtual grid meters.

None. These release notes concern DESS related changes to the VRM backend and portal, not VenusOS. These are mostly unrelated in so far that VenusOS only executes a forward looking SoC schedule that gets pushed to it by VRM.

I spent a few days looking at and testing the option to manually adjust the consumption forecast. In my opinion, it’s a nice gimmick. It’s an option, but personally, I don’t want to adjust my forecast every day. I think it would be better if the forecast logic were expanded to include a few more factors. Let me explain with an example. Many of us now manage our consumption based on criteria like solar surplus and electricity prices. This means, practically speaking, that we charge our electric cars when there’s a surplus of electricity or when prices are extremely low. Either when it’s not worth feeding electricity into the grid or when purchased electricity is particularly cheap. This is a factor that the consumption forecast either doesn’t consider at all or considers far too little. The reverse is also true. The last few days have been extremely sunny. Every electric car was charged, every load of laundry was done, and the heating system was replenished. Consequently, the consumption forecast is at its maximum. Now, a rainy day is coming, so we’ll produce very little electricity but also consume much less. The consumption forecast will be completely inaccurate. Personally, I don’t experience any disadvantages because the storage capacity is sufficient. But as mentioned above, before making any manual adjustments, I would expand the logic. Have a nice Sunday, everyone.
