Our MQTT Broker Just Got Its Own Web Client!

The MQTTHQ public MQTT broker has always been an important part of the EMIT IoT project, so we thought you’d like to know that we’ve just added an easy-to-use MQTT web client. Now, when you connect your EMIT (or any other IoT device) to this broker, you can instantly subscribe and publish to your device's topics without having to write or download any code! More details below. Read the full update.

Adding Full Arduino Support!

One week left! After several questions and much discussion, we are delighted to announce that we will now be publishing our step-by-step tutorials in both MicroPython and C/C++ (using Arduino IDE). We want to make it as easy as possible for you to develop EMIT code in your preferred programming language and IDE. This update also includes a list of tutorials that we plan to release by the time we EMIT ships to backers. Read the full update.

Being Reminded That IoT Is About More Than Just Hardware

It's easy to think of EMIT as a 'hardware project.' Even for us. But the past week has been full of stark reminders that there's a lot more to IoT that just the hardware! The good news is that, after a fairly stressful week, we have improved EMIT's firmware significantly and released an open source MQTT monitoring tool that you might find helpful when implementing your own projects.

LIVE Dashboard Released

Announcing the release of the EMIT 'LIVE' Dashboard, a full-featured, realtime environmental-monitoring dashboard for EMIT. We've done the coding work and integrated the dashboard with MQTTHQ.com (our free public MQTT broker) so that anyone using or developing with EMIT can immediately test their work without having to write any test or application code. If you'd like to have a look, there is now an EMIT in our office, and it's streaming temperature, humidity, and relay-status data every five seconds or so. Read the full update.

Our Public MQTT Broker Is Up and Ruinning

Wow, what a week. With your help, we made it to 25% of our funding goal in just a few days. Thank you for your support! We have some other exciting news, as well. One of the objectives of this project is to provide a highly reliable, public MQTT broker that is available for anyone to use for FREE! And, after several weeks of testing, we are delighted to announce the formal release of MQTTHQ.com – a load-balanced, multi-node, MQTT broker cluster. Read the full update.
