datadis-exporter

CLI tool that uploads the energy consumption and maximum power usage data from the DATADIS API to influxdb on a daily basis

Dependencies

• go
• influxdb v2+
• Optional:
  • make - for automatic installation support
  • docker
  • systemd

Relevant documentation

• DATADIS
• InfluxDB API
• Systemd Timers
• compose-scheduler

Installation

With Docker

docker-compose

1. Configure datadis_exporter.json (see the configuration section below).

2. Run it.

   docker compose up --detach

docker build & run

1. Build the docker image.

   docker build . --tag datadis-exporter

2. Configure datadis_exporter.json (see the configuration section below).

3. Run it.

   docker run --rm --init --tty --interactive --read-only --cap-drop ALL --security-opt no-new-privileges:true --cpus 2 -m 64m --pids-limit 16 --volume ./datadis_exporter.json:/app/datadis_exporter.json:ro ghcr.io/rare-magma/datadis-exporter:latest

With the Makefile

For convenience, you can install this exporter with the following command or follow the manual process described in the next paragraph.

make build
make install
$EDITOR $HOME/.config/datadis_exporter.json

Manually

1. Build datadis_exporter with:

   go build -ldflags="-s -w" -o datadis_exporter main.go

2. Copy datadis_exporter to $HOME/.local/bin/ and make it executable.

3. Copy datadis_exporter.json to $HOME/.config/, configure it (see the configuration section below) and make it read only.

4. Copy the systemd unit and timer to $HOME/.config/systemd/user/:

   cp datadis-exporter.* $HOME/.config/systemd/user/

5. and run the following command to activate the timer:

   systemctl --user enable --now datadis-exporter.timer

It's possible to trigger the execution by running manually:

systemctl --user start datadis-exporter.service

Config file

The config file has a few options:

{
 "InfluxDBHost": "influxdb.example.com",
 "InfluxDBApiToken": "ZXhhbXBsZXRva2VuZXhhcXdzZGFzZGptcW9kcXdvZGptcXdvZHF3b2RqbXF3ZHFhc2RhCg==",
 "Org": "home",
 "Bucket": "datadis",
 "DatadisUsername": "username",
 "DatadisPassword": "password",
 "Cups": "ES0000000000000000XX0X",
 "DistributorCode": "1"
}

• InfluxDBHost should be the FQDN of the influxdb server.
• Org should be the name of the influxdb organization that contains the energy consumption data bucket defined below.
• Bucket should be the name of the influxdb bucket that will hold the energy consumption data.
• InfluxDBApiToken should be the influxdb API token value.
  • This token should have write access to the BUCKET defined above.
• DatadisUsername and DATADIS_PASSWORDshould be the credentials used to access the DATADIS website
• Cups should be the Código Unificado de Punto de Suministro (CUPS)
• DistributorCode should be one of:
  • 1: Viesgo,
  • 2: E-distribución
  • 3: E-redes
  • 4: ASEME
  • 5: UFD
  • 6: EOSA
  • 7: CIDE
  • 8: IDE

Troubleshooting

Check the systemd service logs and timer info with:

journalctl --user --unit datadis-exporter.service
systemctl --user list-timers

Exported metrics

The consumption DATADIS API call period is limited to the last 30 days by default. The power call is limited to the current year's first and last day.

• consumption: The energy consumption in kWh
• period: The period type (p1: punta, p2: llano, p3: valle)
• cups: The cups corresponding to the consumption point above
• max_power: The highest electrical power demanded in kWh

Exported metrics example

datadis_consumption,cups=ES0000000000000000XX0X,period=1 consumption=0.123 1672610400
datadis_power,cups=ES0000000000000000XX0X,period=1 max_power=0.123 1686869100

Example grafana dashboard

In datadis-dashboard.json there is an example of the kind of dashboard that can be built with datadis-exporter data:

Import it by doing the following:

1. Create a dashboard
2. Click the dashboard's settings button on the top right.
3. Go to JSON Model and then paste there the content of the datadis-dashboard.json file.

Uninstallation

With the Makefile

For convenience, you can uninstall this exporter with the following command or follow the process described in the next paragraph.

make uninstall

Manually

Run the following command to deactivate the timer:

systemctl --user disable --now datadis-exporter.timer

Delete the following files:

~/.local/bin/datadis_exporter
~/.config/datadis_exporter.json
~/.config/systemd/user/datadis-exporter.timer
~/.config/systemd/user/datadis-exporter.service
