Automatic equalisation not working on RS 48/6000

Hi, and happy new year everyone!

I have a strange issue, regarding the automatic equalisation:

no matter what battery chemistry or whatever settings I try in the app, the automatic equalisation never starts. If I manually start, it is working but never in auto mode.

The device is an Inverter RS 48/6000 SmartSolar, with latest app and firmware.

Attached are screenshots with my latest settings. I already tried all battery types in the menu, experimented with different voltage thresholds, etc, it is just not working.

Can someone explain me EXACTLY what conditions should be met for automatic equalisation to trigger? Is this a fw bug or I’m completely missing something?

Thank you!

best regards,
