  • Via a MQTT Host/Broker
    • The unit will be serving as a MQTT client 
    • MQTT settings can be set at the settings page of the web UI 
      • MQTT Status: Can enable or disable MQTT Mode 
      • MQTT Broker Host: IP address of the MQTT broker. Can be local or public.
      • MQTT Broker Port: The port that is going to be used for MQTT communication, check with your MQTT Broker
      • MQTT Client ID: Unique id for the client to be connected to the MQTT Broker
      • MQTT Username / Password: These are for the client to be authenticated at the MQTT Broker
      • MQTT Topic: Prefix of all MQTT messages.
      • MQTT Heartbeat Interval : MQTT keepalive time ,which the client commits by sending regular PING Request messages to the broker
      • MQTT Topics ​​
