Integration of Sunlit battery


I´m fairly new to home assistant so please be gentle.
I´m looking for a way to integrate my sunlit battery in home assistant and the deye inverter. I know the deye inverter has a web page which can be locally accesed but getting information from that page to HA i´m completely clueless.

The sunlit battery has an app which integrates the inverter, the battery and the shelly to just insert the power which is needed in the moment.

Thanks in advance
