Multi RS AC input control stays connected to the grid

[Koning]

Hi, I installed a Multi RS 6000 / 48 with 2 Pylontechs US5000 in a tiny house (still building).
No PV panels yet, they come when the house is moved in a few months.

So nearly off grid, with backup of the grid situation. No solar feedin.
Set the gridcode to none.

After install I update in VRM the firmware of the multi to latest 1.23.

But now the AC In input control (Victron connect) is not switching the muli RS off the GRID. It stays connected all the time.
It was working before in the older firmware.

Is this a bug in firmware v 1.23 ?
How can I get this working again ?

Hello,
Can you post the AC input control page settings?
Generally the algorithm can be said that it’s “synced” when one of the “end interval” conditions are met and triggers a connect or disconnect.

I charged the battery to 100% with 'keep battery charged". Then switched on the AC input controls. And it works again…
