Why on earth is victron not able to remove the most obvious strange misbehaviour out of DESS that is annoying for many month now??? Besides some improvements over the recent months, there are obvious errors in the DESS code that prevent it from properly working, making it still pretty useless. *) …

I watching this situation for a long time, and more others too. I’ve only one answer to this question. [image] woody888: Why…??? [image] woody888: PLEASE FIX THAT, THAT COSTS A LOT OF MONEY !!! That’s why. It costs a lot of money to you, but not to Victron. :joy:

[image] woody888: On another system with pretty stable consumption curve over many weeks, and a power pricing that offers cheap to free energy prices during noon almost every day, the system charges the batteries only half for no good reason, that leads to buying expensive power during the night…

Aside the importance of having the system performance parameters set as accurately as possible, there seem to be a recurring issue with the DESS algorithm(s) not being aligned with what is generally being expected from them. Could you elaborate a little more about the current and future development…

I’m not aware of any new modes or future integrations. We are continiously monitoring user feedback, system-scheduling and system-reaction and derrive improvements on (frequently) occuring issues, yet, rolling out even tiny changes affects several thausand systems, so need to be tested well, before…

[image] dognose: Also keep in Mind, that the DESS-Scheduler has to make decissions BEFORE any moment in time That, is absolutely understood. Still I’d argue that Victron bit off a little more than it can chew by shielding off two and only two DESS algorithm models behind a cloud wall that’s …

I have still the issue with FW 3.62 that batterie sell to grid. Today 18:03 [bat2grid1] a little bit later 18:17 [bat2grid2]

Maybe have a look at what some of us are trying to do about that ourselves : [image] Another Strange DESS behaviour DESS Why do have such large differences set in sell and but price? I think that can really skew DESS of track (unless that is really what your e…

[image] Heinzi00: I have still the issue with FW 3.62 that batterie sell to grid. Do you have a battery2grid restriction that should not allow this to happen, or why is that an issue? Or do you just expect something different to happen for that moment in time?

That might have been poorly phrased from my side. The timing wasn’t very well chosen — electricity was sold from the battery, and shortly afterward, the battery had to be recharged at a higher electricity price. Unfortunately, too often electricity from my battery is fed into the grid, and as a resu…

This failure to support self consumption at night is a major issue for me as well. At the moment I use only ESS because it ends up saving me more money. Our bathroom floor heating seems to be one troublemaker for DESS. It’s a 1-2kWh 0.8kW load that occurs 1-3 times a day, at totally random times. I…

DESS ... sadly even with FW 3.62 still the same stupid and obvious errors
