In one of the last blog posts,we took a closer look on the available MQTT client tools out there. While these all of these tools work great, they have a drawback in common: You need to download and install them. Some they don’t work on all operating systems. And others don’t support all MQTT 3.1 features like username/passwords.

We are proud to present aMQTT client, which implementsall MQTT 3.1 features and whichruns on any operating system. Introducing theHiveMQ Websockets Client.

This client runs on any modern browser (sorry Internet Explorer <10!) and you can use it to publishand subscribe at the same time. Under the hood it leverages the awesomeEclipse Paho Javascript library for MQTT andZurbs Foundation as CSS framework.

This web client works perfectly with anyHiveMQ MQTT broker with websockets enabled. Now let’s take a closer look on the features of the web client:

Connecting the Client

Connecting with mqttdashboard.com

You can connect to any HiveMQ (even a broker running on localhost!) with all the MQTT 3.1 features you want to use like Last Will and Testament and Username/Password. It’s of course possible to use secure websockets which use SSL to encrypt your traffic.

Subscribe

A few subscriptions

You can subscribe to any number of topics you want. Topic wildcards are fully supported. All topics subscriptions are marked with a color of your choice to differentiate the incoming messages on that topic subscription. When clicking the “X” on a topic subscription, you can unsubscribe from the topic.

Incoming messages

Incoming messages appear in the “Messages” panel and contain all relevant information about the publish like Quality of Service, topic and a timestamp.

Publish

Publishing via the web client

The web client supports publishing of messages with all characteristics a MQTT publish can have likeQuality of Service and theretain flag.
