IMEON Status Exporter

This is a simple python tool to extract and expose the state of an IMEON 3.6 Smart-Grid Inverter. The code works with the IMEON OS One internal API by quering some JSON endpoints after loging-in with default credentials.

The main use of this code is to create a prometheus exporter from the IMEON data.

Installation

git clone https://github.com/besnardjb/imeon_monitor
cd imeon_monitor
pip install .

Systemd Integration

A systemd example unit is given here

##!!! FIRST edit the file to you needs particularly the command
##!!!
# As root add the unit
cp imeonm.service /etc/systemd/system/
# Update units
systemctl daemon-reload
# Start the Unit
systemctl start imeonm
# Check it runs
systemctl status imeonm
# Enable it
systemctl enable imeonm
# Debug with 'journalctl -xe -u imeonm'

Usage

usage: imeonm [-h] -i IMEON [-s] [-S] [-u] [-d] [-f] [-b] [-l] [-t SCAN_PERIOD] [-p] [-P PROMETHEUS_EXPORTER_PORT]
