OpenMetrics/Prometheus exporter for IKEA sparsnäs energy monitor

Receiver for the IKEA sparsnäs energy monitor using RFM69 radio module. Exposes the data in openmetrics format (that prometheus can scrape).

Usage

USAGE:
    sparsnas-openmetrics [OPTIONS] <SERIAL>

ARGS:
    <SERIAL>

OPTIONS:
    -h, --help                                                 Print help information
    -o, --openmetrics-port <OPENMETRICS_PORT>                  [default: 3030]
        --openmetrics-listen-addr <OPENMETRICS_LISTEN_ADDR>    [default: ::]
    -p, --pulses-per-kwh <PULSES_PER_KWH>                      [default: 1000]
    -v, --verbose
    -V, --version                                              Print version information

An example unit file for systemd (sparsnas-openmetrics.service) is included, which needs to be modified to have correct serial number before linking it.
