Discharging: The load is not distributed in an optimally efficient manner

v1.2.1

Describe the bug

I have tested v1.2.1 for 2 days now and noticed the following issues:
Configuration: 2xSF2400 controlled with Zendure Manager in smart mode

• Splitting of the load
  In the discharge situation, the smart modes divides the load between both devices starting at around 800W. Since the efficiency is only acceptable from 700-800W, the devices with 2x400W then work in an area with poorer efficiency.
• Load changes
  During load changes (charging<>discharging), the system often remains in standby for up to 60s before the direction is changed. This was faster with 1.1.3.
  I've now gone back to 1.1.3.

To Reproduce

Only possible in live situation.

Expected Behaviour

System should split load only, if the splitted values are within an efficient range.
In cause of load change (charge<>discharge) the system should react much more faster.

Happy new year to all
to "Splitting the load":
I'm new to Z-HA (used ioBroker before) and have observed the same issue sometimes within the last 10 days with two hypers, max. 800W each, "own fuse group, "cloud" connection and Zendure Manager in "smart mode", ) in 1.14.pre10. (HA latest version)
(Did not update yet to 1.2.1, still setting up my HA in general, and therefore did not ask for this issue)

With AC load of two decives needed , it looks like there is a hysteresis (by time? and/or load?) after that one device gets back to AC out = 0W again.
Can anyone confirm this ?
It would be much appreciated to add the "Back to single device power output" strategy to the "Power distribution strategy" manual, too.
A great job with the Z-HA Integration. Thank you for this integration.

Some pictures from 31.12.2025 AC out

SoC

Details from 01.01.2026 total AC out about 300-350W. Should be done by one Hyper, only (max. 800W).

Do you run the devices in "local" mode?
