sml2mqtt

A simple yet extremely flexible sml to mqtt bridge

sml2mqtt is a asyncio application that can read multiple sml (Smart Message Language) streams from energy meters and report the values through mqtt. The meters can be read through serial ports or through http(s) (e.g. Tibber devices)

To read from the serial port an IR to USB reader for energy meter is required.
