Do I need to do anything special to connect to my TTN (www.thethingsnetwork.org) broker?

Why are the parameter labels for the modules displayed oddly in the UI?

What do each of the MQTT Modules do in simple terms?

MQTT Transmission

How do I exclude tags from being included in Transmission Sparkplug message payload

How do I exclude tags from being stored in a configured HistoryStore when Transmission is offline

What does the MQTT 'Transmission Control/Refresh' in the MQTT Transmission tag provider do?

Why is my history store flushing slowly and the current live values not being sent

MQTT Engine

How do I persist alarm and history configurations for MQTT Engine tags?

How do I manage UDT definition changes at the edge?

If I delete and update a UDT definition in MQTT Engine will all of the existing instance's member Tags lose their custom properties and configurations (such as history)?

  • Yes, if a UDT definition is deleted and recreated, any existing UDT instances will lose any custom properties and/or configuration.
