DESS in Green-Mode sometimes shows 3 unexpected behaviours: Charging, when there is enough solar available later the day (I1) Discharging to grid, even if the battery is not fully charged (I2) Not charging/discharging, but idling and sending solar-overhead to the grid, even if the battery is not f…

So, have drawn a decision tree :slight_smile: Hope that makes it somewhat clearer for those interested in it. In green you’ll find the respective “final strategy” i’m showing in the cerbo-ui. (This is evaluated every 4 or 5 seconds) [Logic]

The flowchart is very nice, although there’s a point that had me scratching my head. “SoC < TargetSoC ?” → No (so SoC ≥ TargetSoC) → “Solar+ > Consumption ?” → No → “TargetSoC < SoC ?” (so SoC > or = TargetSoC) It all fits and computes, only the usage of < vs > in different steps, SoC and TargetS…

Anyone else having such an alert: [2024-10-26 13_56_38-DaSa - VRM Portal] [2024-10-26 13_57_14-Remote Console on LAN]

Yes have this as well. Means DESS/VRM is currently not generating a schedule. I also noted, that during the past days, “tomorrow prices” became available quite late. I assume this may be the cause, for DESS/VRM not beeing able to generate the schedule for the noon “in time”. (The hack in this cas…

What is happening? I have had this phenomenon before but I am not observing it at the moment. Prices and schedules are usually available at 1:30 p.m.

It’s a global problem, many have it at the moment: [image] Gateway - DESS error code: No matching schedule available DESS Hello, Starting from today there’s an error in VRM: “Gateway - DESS error code: No matching schedule available”. Anybody has the same issue? [imag…

may be daylight time saving problem…may be fixed on sunday :slight_smile:

Does this Hack work on beta vrm 3.50~38?

no, look here: [image] dognose: Installation for Version 3.41, 3.42: [image] [DESS HACK] Unexpected Bat2Grid and Solar-Feedin. (Green Mode) Modifications I’ve now thought about this, and how to solve it - and I think the only way to address this, is a user-preferen…

I don’t know if it might work with the beta. I only have a “production” system, so not running betas on it, can’t test. On regular realeses I will verify the changes within 1 or 2 weeks and eventually make some adjustments when required.
