JSON MQTT LoRaWAN Helium - read and write

Agents, Protocols and APIs
2

Hi Andy,

OpenRemote doesn’t have an example configuration for the Helium LoRaWAN network. I could imagine that configuring MQTT topics is similar to Chirpstack or The Things Network (see tutorial: Receive LoRaWAN sensor data from ChirpStack and also the following The Things Network related forum post).

The aforementioned Chripstack tutorial describes how to extract asset attribute values from a MQTT JSON subscription topic for each asset attribute individually. I think it’s not possible to do that in a single step for all asset attributes.

The configuration for sending data by means of MQTT should be similar to receiving MQTT data. I think you will need the following configuration items:

  • Custom attribute (value type: Text, Number, Boolean …)
  • MQTT Agent link
  • ‘Write Value’ agent link parameter which contains the JSON structure with a {$value} placeholder
