Integration OFF grid possibility

[MRE1985]

On the sigen gateway there is a possibility to go OFF GRID with a button in the Sigen app.
Also the percentage off reserve in case you go OFF GRID is only in the Sigen App.
Unfortunately in the integration these options are missing. I would be very nice to have these options via HA.

I agree and a request has been made to Sigenergy.

I would also very much love this ability to go on and off grid from HA.

Hi Andrei, any updates from Sigenergy re. this ? Cheers

Try this on a dashboard card for the off grid timer

The friendly names change depending upon the battery charging, discharing, floating and the target SoC % (i.e. 100% if charging or say 20% / 0% if discharging). Save this into /packages/sigenergy_battery_calculation_engine.yaml
