Growatt-inverter.php does not work anymore

[PieterS]

Thank you for this information and effort to build this extension.

I looked at https://github.com/johanmeijer/grott/pu ... a897a1f02a

Can you explain where to write which IDX is used for the each different counter?

I guess that is done at line 12? But that line starts with "serial_id":

I think it is this line (but I am not sure)
try:
meter_idx = conf.extvar[xx]
