Eastron SDM Modbus data collection library

An SDM230 meter emulator with an ESP8266 that communicates with a Growatt inverter via RS-485 enabling power export limitation functions

A python based CLI tool to request data from SDM energy counter via modbus. I wrote it for my own needs so currently only SDM630, SDM230 and SDM220 are implemented. Outputformat is a CLI output and a influxlineprotocol compatible output
