Prometheus exporter for smart meter statistics fetched with a P1 cable.
With Go get:
$ go get github.com/jordyv/prometheus-p1-exporter
With Go install (recommended):
$ go install github.com/jordyv/prometheus-p1-exporter@latest
Make:
$ git clone https://github.com/jordyv/prometheus-p1-exporter.git
$ cd prometheus-p1-exporter
$ make
$ sudo make install
Usage of ./prometheus-p1-exporter:
-apiEndpoint string
Use API endpoint to read the telegram (use for HomeWizard)
-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
-usbserial string
USB serial device (default "/dev/ttyUSB0")
-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 https://127.0.0.1:8888/metrics. This endpoint can be added to your Prometheus configuration.

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.
