- 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
