SunsynkDongler2

Hello, I have recently had my solar and inverter installed and am looking into how best to control the system with HA. Just moved to octopus flux, so would be interested in controlling charge/disharge rates and times - similar as can be done with the 'SmartDeyeDongle v4' - https://www.youtube.com/watch?v=IktkBl3inTA&ab_channel=SmartHomeIntegrations Is it possible to set up similar control with this add on? I've used HA for a year or so (mostly for linking devices from different brands), but never ventured too much into custom automations. I've installed the add on, and it appears entities are being read correctly, but I'nm struggling with how to write settings to the inverter. If I can't, then I guess i'll buy the SmartDeyeDonglev4 and replace the exisitng Sunsynk dongle, although it seems a shame when control can be done through the Sunsynk and there's a 2 week delivery on the new dongle!
