I have been using dynamic ESS for almost a year and was happy with it.
4 days ago, the DESS settings disappeared from my menu and is no longer applied even though the toggle in the control panel is still green.
What happened?
I did not change anything!
I am quite sure that is related to a change we did to add support for the Multi RS and this is a side-effect of that.
Will take a more close look tomorrow, but what I see is that you are running your site with Venus GX version v3.11. I am almost certain that, if you update to the latest stable version (v3.33 on regular, v3.34 on the large image), the DESS menu will return.
Also note that between version v3.11 and v3.33 we did quite a lot of Dynamic ESS related fixes within the firmware. So also from that point of view it is advised to update.
Hi, I see this behavior as well. I have a lot of trouble getting it all stable.
My setup is 2 JK BMSes with dbus-serialbattery, BatteryAggregator, A Smart Shunt, MP II 5k and SDM630 meter
Versions: all latest, VenusOS on Raspberry Pi 3.
When the inverter is just inverting it's all fine, I set my setpoint to -30W.
ESS configuration goes fine. When the ESS decides to pull or deliver from the network it goes fine for some time (this evening around 45 minutes).
After 45 minutes I get these messages:
| Gateway | Dynamic ESS error code: ESS functionality not available |
The do not go away themselves, sometimes a reboot helps, mostly not.
Then I have to go into the MPII menu and switch it off and on.
Is there some debug I can perform to give insight in where this is going wrong?
I often see following message
cat /data/log/vedirect.ttyUSB2/current | tai64nlocal |less

Thanks for any pointer which can help.

I would like to second this! For the last month I regularly have the alarm 'No matching schedule available' on the VRM website. No menu for the DESS settings any more. Cerbo FW version 3.11. I can turn DESS on and off, but the system just uses the 'Grid point' setting. Please advise!
Yes, this worked.
Thx
Is there any reason not to enable auto updating?
For most installations I suggest setting it to auto update to the latest official release. Only in exceptional cases it is better to stick to a certain version and not update.
Yes, that worked also for me, apparently a backwards compatibility issue.
Is there a way to give a warning in the betavrm environment that an update is needed?
Regards
Hans
