Sensor (MQTT)

Connect and subscribe to real-time data streams using MQTT protocol.
This feature is ideal for integrating IoT devices, sensors, or any system that communicates via MQTT.
This works very similar to Database (https://lygos.io/docs/data/database)
Live updates coming from sensors or IoT devices can be fed to data visualizations and maps on your video wall or live dashboards.
integrate IoT devices, sensors or any system with MQTT

  • Host: URL of MQTT Broker
  • Port: Port of MQTT Broker
  • Connection:
    • Websocket with TCP/SSL
    • Websocket Unsecure
    • MQTT with TCP/SSL
    • MQTT Unsecure
  • Username/Password: Optional Authentication
  • Reconnect Timer: Checks connection every X seconds and if connection is dropped, reconnects and resubscribes.
  • Data Window Size: This is how many past results are stored in your data window.
    • Data Windows can be used for animations of data visualizations.
    • If Data does not have datetime values, data receival time can be used as its temporal value, and thus be animated.
    • For example, polling data every minute and with window of 60, you can animate your last hour with 60 data points on data visualizations and maps.
  • Data Polling Mode: You can determine if the query is polled on demand or on in the background.
    • On Demand: Data is temporary. It is polled only if a visualization is actively using this data source on the screens.
    • On Background: Data is persistent. It is polled on the background and data window is stored when app closes or relaunches.
  • Data Format: Determine Data Format of incoming data through our Data Format Tool.
  • Preview Results: instantly to validate your data before use in visualizations.
    • Raw Data: You can see incoming data from MQTT
    • Formatted Data: Your final data source after your data is formatted.
