SMA SB3.6-1AV-41 Firmware 3.0.7R + Python 2.7/3.7 (Debian 10 Buster)

Error:

my config:

slave = 3 model = "sma-SBn_n-1AV-40" timeout = 3 scan_interval = 10

i commented out the useless data from modbus-sma-SBn_n-1AV-40.py

['30531 - Total yield (kWh)',30531,'U32','FIX0'], ['30533 - Total yield (MWh)',30533,'U32','FIX0'], ['30535 - Daily yield (Wh)',30535,'U32','FIX0'], ['30537 - Daily yield (kWh)',30537,'U32','FIX0'], ['30769 - DC current input [1] (A)',30769,'S32','FIX3'], ['30771 - DC voltage input [1] (V)',30771,'S32','FIX2'], ['30773 - DC power input [1] (W)',30773,'S32','FIX0'], ['30775 - Power (W)',30775,'S32','FIX0'], ['30783 - Grid voltage phase L1 (V)',30783,'U32','FIX2'], ['30953 - Internal temperature (C)',30953,'S32','TEMP'],

is enough for me.

work perfect with influxdb 1.x, python 3.7.x and a SMA SB3.6-1AV-41 Firmware 3.0.7R

Looks like there are slight differences between models / versions and modbus maps. Good work on getting the data you need.
