Minimalistic setuptool for the Eastron sdm120 wattmeter. Its primary usecase is the setup of the ID and the baudrate.
Note that this tool is more minimalistic than gianfrdp/SDM120C and just supports changing the modbus setup values.
- python3, python3-minimalmodbus
- e.g. pip3 install minimalmodbus
Call the help page: ./setuptool.py --help
Check connectivity of meter with ID==2, baudrate==2400 (default)
./setuptool.py --meterID=2
Note that currently it's not able to set the meterID and baudrate
to a new value at the same time, due to the nature of
the meter which changes the value immediately.
To change both values one has to follow this example
Set the Baudrate to 9600 of meter with ID==2
./setuptool.py --meterID=2 --setBaudrate=2
Set meterID to 42 of meter with currentID==2
./setuptool.py --serialBaudRate=9600 --meterID=2 --setMeterID=42
