Wireless Sensor Tags (http://wirelesstag.net) are small sensors which measure humidity, temperature and ambient light level, and transmit this back to a hub to be stored in the cloud. This app uses the WirelessTag API (http://wirelesstag.net/apidoc.html) to query that data, transform it, and ingest it into an ElasticSearch instance for creating dashboards, plotting trends, etc.
As an added bonus, the process can also query the historic temperature of a Hive Home heating system Thermostat, and ingest that data into the ES index too. If you have a Weather Underground (WUnderground) API key, you can also specfy this in the settings, along with a country and city, and the app will pull in complete weather data history for that location and ingest it into ElasticSearch.
- Year-based index generation (e.g., sensordata-2017) with top-level alias creation (e.g., sensordata)
- High-watermark checking for each device UUID so only new data is ingested on each run
- Automatic detection of new tags when registered with your account
- Collection of temp (C), humidity (%RH), ambient light level (lux) and battery-level (volt) collection
- Optional configuration to send an email if no data received for n minutes, or battery level for any device is too low
- Optional collection of HiveHome temperature and battery data
- Optional collection of Weather Underground weather (temp/humidity/rainfall/wind/etc) data
The service reads the various settings (ES info, WirelessTag username/password) from a json file. It then queries the service, gathering up the data before writing it to the ES cluster/index specified in the settings file. Data is written to month-based indexes, and then an alias created to cover all indexes.
The service is a .Net/C# application, developed with Visual Studio fo Mac. It can be run on any architecture - for example, I run it using Mono, on a linux-based Synology NAS. Example command-line:
mono SensorTagDataCollector.exe
