# MQTT Sync

**MQTT Synchronization** tool is an OntoGuiWeb module that provides an MQTT client that can:

* publish a message on a topic
* subscribe to topics

In addition, it is possible to load a sequence of messages ("Message Sequence") as a JSON list and publish them automatically and iteratively based on a predefined time interval ("Message interval").
