MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol optimized for high-latency or unreliable networks. It is particularly designed for resource-constrained devices and low-bandwidth, high-latency or variable-bandwidth environments, making it ideal for IoT (Internet of Things) applications. MQTT utilizes a publish/subscribe architecture, where clients can publish messages to a specific topic and subscribe to receive messages on a specific topic of interest. This decoupling of publisher and subscriber facilitates scalable and efficient communication in distributed systems.

Use cases

Below you will find typical use cases for MQTT integrations and how they are implemented in Frends.

IoT Device Communication

Many organizations use MQTT to collect and distribute data between IoT devices and central systems. Frends can integrate with MQTT brokers to act as a mediator, collecting data from IoT devices in real time and pushing it to back-end systems or data storage solutions. For example, sensor data from a manufacturing plant could be gathered through MQTT and processed by Frends workflows to provide analytics or critical real-time monitoring.

Smart Home Systems

MQTT is widely used in smart home ecosystems to allow devices like thermostats, lights, and smart security systems to communicate. With Frends, these MQTT messages can be managed and further extended by integrating other applications or services, such as configuring workflows for automated responses based on device status updates.

Transportation and Logistics

In logistics, MQTT is used to track vehicles, shipments, or assets in real time. Frends can subscribe to MQTT topics related to tracking events and integrate this data with enterprise resource planning (ERP) systems or customer portal systems, ensuring accurate and timely delivery information for stakeholders.
