dsmr exporter

dsmr exporter is a daemon that reads smart meter P1 data (dsmr) and converts it to an elastic search document.

dsmr_exporter can read data from:

• multiple serial ports
• multiple esp8266's

This software needs hardware to work. To find out more about the supported hardware, check out docs/hardware.md.

Installation

From source

sudo pip3 install pyserial
sudo pip3 install elasticsearch
git clone https://github.com/pvcbe/dsmr_exporter.git

pip

TODO

Using

This example reads data from the ttyUSB0 serial port and exports the data to host 192.168.0.103

 ./dsmr_exporter.py --serial /dev/ttyUSB0 --elastic-host 192.168.0.103

• Attention: Your user needs read access to the serial device

  export P1_SERIAL=/dev/ttyUSB0
  export P1_HOST=10.0.0.16:5678,172.16.0.2:8898
  export ELASTIC_HOST=192.168.0.103:1234
  ./dsmr_exporter.py
  

This example uses environment variables to read its config:

• serial input on /dev/ttyUSB0
• TCP host 10.0.0.16 on port 5678 and TCP host 172.16.0.2 on port 8898
• elastic search host on IP 192.168.0.103 and port 1234

Options

option	environment variable	default
--p1-serial	P1_SERIAL	-
--p1-host	P1_HOST	-
--elastic-host	ELASTIC_HOST	localhost:9200
--elastic-index	ELASTIC_INDEX	dsmr-%Y.%m

Example dashboard

There is an example dashboard for elasticserach and one for grafana. They are located under docs/dashboards. The grafana source name is elasticsearch-dsmr. Don't forget to create a datasource with that name (or change the dashboard).

Elasticsearch

It is wise to create a rollup job or delete old dsmr indexes. Or to buy more storage as time passes :)
