Netatmo script for telegraf

This repository contains a script for retrieving data of a netatmo weather station for use with telegraf.

First obtain API keys and refresh token from the Netatmo developmer website:

https://dev.netatmo.com/

Dependencies

The script requires ruby 2.0 or newer.

Usage

Usage: netatmo [options]
    -c, --config=PATH                Path to configuration file

Example

Here is an example what data is read from the station (with one outdoor sensor):

$ ruby ./netatmo  | json_pp
{
   "station" : {
      "indoor" : {
         "Noise" : 40,
         "Humidity" : 70,
         "Temperature" : 18.7,
         "CO2" : 615,
         "AbsolutePressure" : 982.3,
         "Pressure" : 1017.6,
         "AbsoluteHumidity" : 11.2
      },
      "outdoor" : {
         "Temperature" : 12.8,
         "Humidity" : 98,
         "AbsoluteHumidity" : 10.97
      }
   }
}

The AbsoluteHumidity values are calculated by the script.

Configuration

The script reads credentials from the /etc/netatmo.yml configuration file:

---
client_id: <hex-value>
client_secret: <hex-value>
refresh_token: <refresh-token>
device_id: <station MAC>

Telegraf configuration

You need to configure a exec input in your telegraf.conf:

[[outputs.influxdb]]
  urls = ["http://influxdb:8086"]
  database = "telegraf"

[[inputs.exec]]
  commands = [""/usr/local/bin/netatmo -c /usr/local/bin/netatmo.yml""]
  interval = "10m"
  timeout = "15s"
  data_format = "json"
  name_suffix = "_netatmo"
