ruuvi-prometheus exporter

This is a simple Prometheus exporter that exports metrics for Ruuvi version 3 data format Bluetooth LE advertisements.

Usage

I use ruuvi exporter with Alpine Linux myself and it’s on Alpine Linux repository in edge/testing.

To use this binary release, install Alpine edge and enable the testing repository and apk add ruuvi-prometheus. Enable service to start at booth with rc-update add ruuvi-prometheus.

You will need to uncomment "rpi bluetooth" in /etc/mdev.conf for Raspberry Pi Bluetooth to work.

The service binds listen address to :9521 by default.

For usage with Grafana, see grafana-example-dashboard.json.

To keep the exporter stateless (I run it on a headless read-only Raspberry), it is better to add the logical names for sensors in Prometheus configuration. For example:

  - job_name: 'ruuvi-prometheus'
    static_configs:
      - targets: ['ruuvi-prometheus:9521']
    metric_relabel_configs:
      # ... id and name relabel config for each sensor
      - source_labels: ['device']
        target_label: 'id'
        regex: 'e7:37:3b:37:d9:74'
        replacement: '2'
      - source_labels: ['id']
        target_label: 'name'
        regex: '2'
        replacement: 'garage'
      # Map location based on id
      - source_labels: ['id']
        regex: '2|3|5|6|7|9'
        target_label: 'location'
        replacement: 'indoors'
      - source_labels: ['id']
        regex: '1|4'
        target_label: 'location'
        replacement: 'outdoors'

Further development

Ideally I would like to run this using gokrazy instead, but my current setup requires WiFi with WPA2 and Raspberry Pi Bluetooth which are not supported yet. Once those blockers are solved, gokrazy can create Raspberry appliance image without any C code besides Linux.
