Hello,
I integrated a Siemens PAC2200 with Modbus TCP to track my import & export comsumption.
I also have SMA inverters integrated with the platform.
Everything is working great but I’d like to add a function to track my electric comsumption.
My electricity provider annually ask me the index of the counter to make the bill.
I’d like to make a variable, somewhere to encode the date which is the last time they ask me, for example this year it was the 30 october 2022
I’d like to make a sensor which will sum my import and remove the export comsumption from this date to now, to have an idea of what I use on the grid since my last bill.
How can I achieve that? I need some advices
Kind regards
