Hello guys,
i’ve a SMA SB3000IT at my mom’s house for a 3KW solar plant.
This unit was never “smart” monitored, my dad just get some optical reader for the counter below the unit (that is attached to the grid). Now this reader is dead and I want to integrate into a remote Home Assistant to check it.
I see that is possible to install a PiggyBack RS485 card internally, but SMA says that it’s not ModBus and needs to use proprietary software. Is it right?
Thanks for any help
