Connecting IoT devices

You can connect any device, from a thermometer to a vibration sensor, from a soap dispenser to a motion detector.

Assetwolf supports connectivity using LoRaWAN (a great solution where low power or long distances are needed), or using wifi or cellular (where power is available, or data is more frequent).

LoRa devices use the LoRaWAN protocol, so if you're using LoRaWAN then your devices will connect to your on-site gateway, and then onto the internet. Assetwolf includes a ChirpStack dashboard to manage devices, which in turn passes data to the Assetwolf portal.

If your devices use wifi, ethernet or cellular data, then they may be able to use:

• MQTT-capable devices can connect directly to Assetwolf's MQTT broker
• Https-capable devices can make a REST request to Assetwolf's web server.

AssetWolf can receive data in one or multiple formats, all at once. 

Sensors can send data in LoRa base64 format, as one-field-per-request, in JSON format, and as XML.

Once the data is ingested into AssetWolf, it's treated the same and goes into the same analysis engine.

Where data is already fed to a third-party platform, Assetwolf may be able to fetch the data from that platform periodically.

The third-party platform will need to have an API (please contact us for details).

Once acquired, Assetwolf processes the data in the usual way, and merges it with data acquired from other sources.

A schema is used to define each type of IoT device that you use. 

You can define the incoming data fields, metadata (constants) for each device, and fields that are calculated in real time as data arrives.

Fields can be floating-point, integer, boolean state, text, or geographical co-ordinates.
