Read energy/power exported to grid #2

Hi,

Really nice work! I would like to implement something similar with my Growatt inverter. I also have a smart meter which gets data of energy exported/imported from the grid. I'm trying to retrieve that data using inputs registers from 1015 to 1030 from the documentation but I'm only getting 0s as values. I don't know if you have also try to read this data.

Thank you in advance!

Hi @dst10 thanks. What I found when implementing it was that there are many contradicting documentations available. I guess values differ for firmware or inverter versions. You can do some trial and error using to find the documentation that matches your inverter. If you find some time you can also contribute it to the library if you find the solution
