Support for SB3.0-1AV-41 224 about solariot HOT 7 CLOSED

from solariot.

oh nvm, 30357 is without data.. sorry.

i look for a fix, this evening.

but the rest is working now

@knights1
set your timeout higher, 3 seconds is too fast.
20 seconds is better and safe some database space

from solariot.

config at the moment:

inverter_ip = "192.168.1.166"
inverter_port = 502
# Slave Defaults
# Sungrow: 0x01
# SMA: 3
model = "sma-SBn_n-1AV-40"
slave = 3
timeout = 3
scan_interval = 10
# Optional:
# dweepy_uuid = "random-uuid"
# Optional:
influxdb_ip = "192.168.1.91"
influxdb_port = 8086
influxdb_user = "xxxx"
influxdb_password = "xxxx"
influxdb_database = "inverter"
influxdb_ssl = False
influxdb_verify_ssl = False
# Optional
#mqtt_server = "192.168.1.91"
#mqtt_port = 1883
#mqtt_topic = "inverter/stats"
# See config-example.py for required and optional settings.

this gives me an error:

[ERROR] fromRegisters() got an unexpected keyword argument 'endian'

from solariot.

Your inverter model may not be supported by the contributed modbus map. However, try dropping the endian field from Line 137 to be:
message = BinaryPayloadDecoder.fromRegisters(received.registers)

from solariot.

This doenst work, after this change i get wrong results.

try this:

message = BinaryPayloadDecoder.fromRegisters(received.registers, byteorder=Endian.Big, wordorder=Endian.Big)

in pymodbus 1.4.0 they changed the endian-stuff a little bit.

looks good for me

before, i got extreme high results (68000 watts in the night, yay!)

from solariot.

from solariot.

the adress is 30537

i started the logger again with a clean database in the night, so the sma modbus do not transmit DC related things. When the sun go up/rise/myenglishistoobad the inverter started and sent these datas.

when you use python3, you must install everything with pip3, not pip. this is a littlebit confusing, python is a version-chaos. python2 and python3 are complete different spaces. afaik you can use python2, there is no must-to-have python3 things in this code.

also use python instead of python3.
