Get values from modbus energy meter to MQTT / HomeAssistant

Energy Meter -> modbus -> RS485-USB-Adapter -> energymeter2mqtt -> MQTT -> Home Assistant

The current focus is on the energy meter "Saia PCD ALD1D5FD" However, the code is kept flexible, so that similar meters can be quickly put into operation.

Quick start

Overview:

• Clone the sources
• Create your config: ./cli.py edit-settings
• Test: ./cli.py print-values
• Setup and start MQTT publishing: sudo ./cli.py systemd-setup

~$ git clone https://github.com/jedie/energymeter2mqtt.git
~$ cd energymeter2mqtt
~/energymeter2mqtt$ ./dev-cli.py --help

Usage: ./cli.py [OPTIONS] COMMAND [ARGS]...
