I use the battery pause functionality on my GE Gen 2 inverter a lot, and would find this proposal useful.
We are on Octopus Flux. During winter, I use Pause Discharge 0500-1550 to ensure enough charge in the battery during the expensive Flux session 1600-1900. The rest of the time, I use pause discharge for similar reasons and times if the generation forecast is poor. It would be handy to have WW do the maths on whether to Pause or not based on the forecast, instead of me doing that manually every evening.
I might use the other two options in WW in specific circumstances if they were available.
