      Supported EEP's and example data

      Overview

      Our gateway receives data wirelessly from all sensors within range (30 metres line of sight), converts the raw data into an easy-to-use JSON format*, time-stamps it, then publishes it using MQTT protocol.

      *JSON (JavaScript Object Notation) is an open-standard file format that uses human-readable text to display data. We use JSON to standardise sensor data across multiple protocols and formats.

      This page gives you examples of the JSON data structures/interchange format for the sensors that we support transmitted from the gateway to the destination system.

      Note: All Device IDS, Names, Locations and sensor values are for demonstration purposes only.

      This information is valid for the latest version of the gateway.

      • MQTT
      • Azure IoT Hub
      • AWS IoT

      Optional payload data

      The below options can be included or excluded from the published payload. This can be configured on the gateway.

      Timestamp – “timestamp” The time the gateway received a message from a physical device.
      Device Name – “devicename” Name assigned to the physical device sending data to the gateway this can be found in your device lists.
      Device ID – “deviceid” Device identification associated with a physical device e.g. ‘01882050’ device id’s can be found in your device lists.
      Device Type – “devicetype” Type of device as found on the devices page. e.g. CO2 Temperature and Humidity.
      Gateway Name – “gatewayName” Gateway name assigned in gateway settings.
      Device Location – “location” Location of a device assigned on the edit device screen e.g. mainoffice.
      Device Values Values received by the gateway from a physical device such as temperature, humidity, current etc.
      Device Values Unit Unit the device value is measured in if available e.g. °C
      Signal Strength – “dbm” Signal strength between the device and gateway in dBm.
      Security – “security” Status of device security on/off.

      Supported EEP's and payload sizes
