prometheus-givenergy

prometheus exporter for GivEnergy inverter metrics

prometheus-givenergy is inspired by givenergy-modbus module. givenergy-modbus does not work with current version of pymodbus.

Usage: prometheus_givenergy <host> [--port=<port>] [--prom-file=<prom-file> [--version]
    <host> ip-address or hostname
    <port> default 8899
    <prom-file> default /var/lib/prometheus/node-exporter/givenergy.prom

All holding metrics are prefixed with givenergy_holding_. And all input metrics are prefixed with givenergy_. The unit type of the metric is used to add a suffix.

Installing on Fedora

1. Install and configure Prometheus and Grafana
2. sudo dnf copr enable barryascott/tools
3. sudo dnf install python3-prometheus-givenergy

Use systemd service and timer units to run the command periodically (or cron if you prefer).

Timer unit: /etc/systemd/system/givenergy.timer

ExecStartPre=/usr/bin/id
ExecStart=/usr/bin/prometheus-givenergy hf-a21.chelsea.private

Once the systemd unit files are in place:

1. sudo systemctl daemon-reload
