In today’s world, the enterprise application system is incomplete without providing a way to integrate with other systems. Ergo,MQTT Broker integration with your application is very crucial for any process / production management application in Industrial and Customer implementation. To make such implementation feasible, MQTTRoute supports many integrations which include Relational DB, Data storage, Queue integration, Application integration, Social integration & finally Application/Mobile integration using REST APIs. Bevywise MQTT broker was built with options to store data into any back end data storage via the custom data store. You can visualize the data by storing the data into the storage. In addition, You can use the ready to use plugin to store data to Elastic and MongoDB. In addition to this, our recent update on MQTT Broker comes up with an extension to store the data in any of the big data engine for powerful analysis & Data hooks for any custom integration.

We are still working hard to make the MQTT Broker work more seamlessly with any of your application. Hence, we support the availability of APIs in our MQTT Broker with some additional interactions through which your IoT Application can manage your edge devices via the MQTT Broker.

Need of REST API Integration

In the digital world, the huge number of cloud / mobile applications & IoT devices keep on rising and hence the businesses are trying to find a beneficial use for these emerging sources. Any how, the biggest challenge lies in integrating these applications with other business operation systems to bring together into a unified whole which can be easily shared within one’s businesses. This is where REST APIs comes in, which permits the interaction between applications & servers to boost the product functional capability & getting data where & when they need it, creating an overall well-connected eco-system.

For example, in order to manage & control business / enterprise assets some organizations make a choice of cloud-based systems. Earlier, Business measures which have been stored within an existing organization are now locked behind such a third-party applications and web interfaces. Business’s need this information to make data-driven decisions, and APIs make that possible. APIs will break down the data access by defining the interactive commands for the application systems. Furthermore, APIs can also be used in the third-party integration tools to call for the data. They can be integrated with other application systems to process business inquiries.

MQTT Broker integration with REST API:

While building an IoT application, there is a need to control and manage the edge devices from the manager application. REST API will help you control your edge devices via the MQTT Broker. It allows you to query MQTT clients, sessions, send messages, add new authentication keys. You can also query and monitor the connected devices.

We have carefully selected the most useful communication that is needed between any application and its broker to provide you the best management experience/functionality. The following are the list of interactions available now

  1. Send a message to any specific device.
  2. Send a message to all devices based on a subscription.
  3. Add a MQTT Device Authentication username and password dynamically from your application.
  4. Remove a MQTT Device Authentication String from the MQTT Broker
  5. Get the list of active devices connected right now to the MQTT Broker.
  6. Get the count of clients connected

One of our customers, FAB Controls is an IoT solution provider in the United Kingdom who provides IoT solutions to the lighting and energy industries. EmMonIT is their elite solution for emergency lighting control. Their emergency lighting control device is efficacious in monitoring lighting steadily to set the seal on operating successfully. MQTTRoute plays an indispensable role in their emergency monitoring solution. MQTTRoute acts a central broker and therefore it collects data from lighting control devices and pushes it to Google pubsub to create simple and real-time visualization of data. Besides this, as MQTTRoute supports REST APIs, the lightning control devices can be controlled & monitored from the manager application. This provides a virtual foolproof emergency lighting by enabling them to constantly check the status of emergency lighting anywhere at anytime.

Unsolicited Messages:

MQTT Broker now supports sending of Unsolicited messages to the Edge Device. Yes, you read it right. You can now send messages to any specific device for a topic for which the client is not already subscribed to. This is an enhancement to support device development platforms like Telit.  Send the http call to /clientsend with the target device, topic provided by the device for receiving unsolicited messages, message, QoS and Retain as required.

We have also added an advanced custom implementation inside the /lib folder of the product to send the data received into your Python class file to process it in a better way.
