Feature request: predicted solar production
I don't want to spend money charging up my batteries overnight from the grid if it's going to be sunny tomorrow. If it's going to be partly sunny I want to partly charge my batteries. Home Assistant can access solar production forecasts, but using it has proved to require more tech geekery than I can muster. So here's what I would like the Sunsynk software to do: Each evening my Sunsynk inverter calculates my average daily power consumption for this time of year. It looks up the predicted amount of power my PV array will generate tomorrow. It calculates how much power I will likely need to buy from the grid, and how many 30-minute slots it will take to charge the batteries with that much energy. It knows the price of electricity for each 30-minute period from the Octopus Agile API and calcualtes the price point necessary to get the requisite number of 30-minute slots. It finally sets the Revenue Info charge battery limit to that price point.
At present I'm doing this manually, looking at tomorrow's prices each evening and choosing a price point to plug into the Revenue Info charge battery setting; a process that surely could be automated.
I am in the UK on Inteligent Octopus at cheap off peak @ 7.5p so it is an advantage to fully charge the batteries each night because if Solar saisfies the house during the day and tops up the battery output prior to the sun comming up, the excess Solar gets exported @ 15p so I am ahead of the game😁 or have I missed the trick? The thing that I try to avoid is using on-peak @ 32p
