Description

This program listens for RuuviTag devices and posts JSON data to HTTP endpoint specified by HTTP_URL environment variable.

Bluetooth implementation relies on Paypal's GATT library. See setup.

Currently supports ruuvi sensor protocol 3.

JSON data looks like this:

{
	"Temp": 1.25, <- temperature celcius
	"Humidity": 94.5, <- relative humidity (%)
	"Pressure": 98760, <- atmospheric pressure (Pa)
	"Battery": 2845, <- battery voltage (mV)
	"Address": "D3:C7:D0:2E:14:D7", <- unique device address
	"AccelerationX": -74, <-- acceleration (milli g)
	"AccelerationY": -156,
	"AccelerationZ": 976,
	"TimeStamp": "2017-12-30T15:02:44.3560173+02:00"
}

I currently use this project to record sensor data from Ruuvi Tags around my apartment. The data is posted straight to ElasticSearch index.

ElasticSearch + Kibana quickstart

Start ELK stack using docker

$ sudo docker run -p 5601:5601 -p 9200:9200  -p 5044:5044 --restart unless-stopped \
    -v elk-data:/var/lib/elasticsearch --name elk sebp/elk

Access Kibana on http://localhost:5601 , navigate to developer tools.

Create index by executing following in developer tools:

PUT ruuvi
{
  "mappings": {
    "data_point": {
      "properties": {
        "Address": {
          "type": "keyword"
        },
        "TimeStamp": {
          "type": "date"
        },
        "Humidity": {
          "type": "float"
        },
        "Pressure": {
          "type": "float"
        },
        "Battery": {
          "type": "float"
        },
        "Temp": {
          "type": "float"
        },
        "AccelerationX": {
          "type": "integer"
        },
        "AccelerationY": {
          "type": "integer"
        },
        "AccelerationZ": {
          "type": "integer"
        }
      }
    }
  }
}

Start posting data.

$ export HTTP_URL=http://<elasticsearch ip>:9200/ruuvi/data_point
$ ./goruuvitag

Explore your data using Kibana :).

TODO

• Listen and parse ruuvi data
• ElasticSearch support
• InfluxDB support
• Precompiled binaries
