9 months ago We've just published a new release, that is more incorporated into the Venus OS and follows the target SOC instead of setting a setpoint and a less than ideal way of idling the battery.
As this uses a different approach, you will need to:
- update Venus OS (to 3.10 or above)
- update the victron-dynamic-ess node to version 0.1.1
- update the example flow
- reconfigure the Dynamic ESS node
More information can be found in the release notes and README.md
Regarding this issue, the new flow will set a schedule for the next 4 hours and will switch Dynamic ESS off if no new schedules can be fetched from the API.

What happened?
During today's testing now I get message Could not create a feasible schedule. I suppose its because of calculation was not successful. But grid setpoint was left at -9900 so batery started to cycle: Discharge into grid to 45% (Life optimized settings), charged to 50%, discharged to 45% etc. Discharge energy was max configured in node. I had to setup gridpoint manually to 0 in remote console.
