Feature request: Scheduled discharge / Less smart DESS

Hi Folks,


Let me know if this already exists (maybe even as part of DESS).

I would quite like scheduled discharging functionality that's a bit more built in that node red + adjusting grid setpoint. Wondered if others feel the same or if I'm a minority.


This would allow me to make a less smart DESS system. Or allow users to make their own DESS system customised to work with their own providers which might be so niche/small that it doesnt make sense to implement for everyone. ie they could query their local providers api and get node red to just adjust the scheduled discharging settings. Rather than having to write logic to dynamically adjust gridsetpoint.


I suppose it's really just a less smart DESS.


My thoughts of how it would work:

Would have a few modes, and schedules would be based on time but also down to set SoCs.


Modes:

1. Export all solar generated (gridsetpoint = - solar)

2. Export all excess solar over loads (gridsetpoint = -(solar-loads))

3. Export x watts (gridsetpoint = -x)



I wasn't sure if there was some functionality built into DESS I could leverage or if DESS just does the same way I would (dynamically adjusting gridsetpoint as notes above).
