Integrate an EnergyOptimizationSystem as Plugin

[finfin82]

It would be cool to have some kind of optimization system that can handle with hourly changing prices, respect solar prediction to build a charging discharging + keep load state for the battery.

for forecast source we could use api.akkudoktor

so what needs to be done

• get hourly prices
• get hourly forecast
• analyse the data
• find the best battery-state plan 6 different times (fort the time of use)
• set those plans using the existing time of use implementation

i have a private project doing this. it works once a day 0:01 it runs and sets my states.
how can i send you my code to review and maybe porting this to a plugin?
@kbialek would be awesome to have such a plugin

questions welcome cheers

hi! If you want to make your plugin public, then well, make it public 😄 at github or any other platform of your choice. Then send me a link and I will add it here https://github.com/kbialek/deye-inverter-mqtt?tab=readme-ov-file#list-of-public-plugins

well its not a plugin at the moment, its some kind of spaghetti-code, but its working. i was hoping you will find some time to make it a plugin and we can optimize it together.

I can maybe review your code and provide some feedback, but will not actively participate in coding for sure. Sorry, I have no time for that.

Thx for your feedback, I will give it a try.

To actively support the plugin, you likely need support for bi-directional charging. @kbialek, I'm interested in the SG04LP3 inverters, but they need to support external regulation. I only want to instruct the inverter to either send 10 kW to the battery or 10 kW to the grid, ideally within milliseconds. Can you share some insights?

FYI: I scrolled through #132, but it didn’t exactly answer my questions. I’m using an external wrapper as a charge controller (https://github.com/tonobo/watti_watchman) for various reasons. I’m considering investing in another inverter and want full control over power regulation. At the moment the victron system is uses as 100% battery inverter and I'm actively telling them to charge and discharge at which rate.
