Prometheus P1 exporter

Prometheus exporter for smart meter statistics fetched with a P1 cable.

Installation

From source

With Go get:

$ go get github.com/jordyv/prometheus-p1-exporter

Make:

$ git clone https://github.com/jordyv/prometheus-p1-exporter.git
$ cd prometheus-p1-exporter

Usage

Usage of ./prometheus-p1-exporter:
  -interval duration
        Interval between metric reads (default 10s)
  -listen string
        Listen address for HTTP metrics (default "127.0.0.1:8888")
  -mock
        Use dummy source instead of ttyUSB0 socket
  -verbose
        Verbose output logging

By default the exporter will collect metrics from /dev/ttyUSB0 every 10 seconds and export the metrics to an HTTP endpoint at http://127.0.0.1:8888/metrics. This endpoint can be added to your Prometheus configuration.

Development

Currently only the ESMR 5.0 format is supported and the parser is default configured to parse the telegram message with the keys the Sagemcom XS210 is using. If you have to support a different ESMR 5.0 message, feel free to create your own implementation of the TelegramFormat struct. To support a different format then ESMR 5.0 you can implement your own implementation of the TelegramReaderOptions struct.
