Run as a service

cp sensehat-exporter.service.example /etc/systemd/system/sensehat-exporter.service
systemctl daemon-reload
systemctl start sensehat-exporter
systemctl enable sensehat-exporter

Usage

usage: simpleexporter.py [-h] [--port [PORT]] [--bind [BIND]]

optional arguments:
  -h, --help     show this help message and exit
  --port [PORT]  The TCP port to listen on (default: 9101)
  --bind [BIND]  The interface/IP to bind to (default: 0.0.0.0)
  --orientation  Enable 'orientation' data (roll, yaw, pitch)

Configuration

Currently there are no other configuration than options IP/port and no configuration file.

Prometheus Configuration

In /etc/prometheus/prometheus.yml, Add a static scrape target under scrape_configs:

scrape_configs:
  - job_name: 'sensehat'
    static_configs:
    - targets: ['<ip>:9101']

TODO

  • Upload example Grafana dashboard
  • Export more sensor data - currently only temperature, humidity and pressure is exported.
  • Possibly make additional sensors configurable.

Demo

Here's a screenshot of the data being put to use in a Grafana dashboard:
