Demo video: “MQTT Push Client” app with custom GUI for MQTT environments

Our “MQTT Push Client” app allows receiving MQTT messages and displaying them in a list or in a GUI (“Dashes”). The GUI allows elements like buttons, sliders, icons, text panels etc. with colors and background images to display or send MQTT messages. In addition, the Custom View dash allows designing the complete element using HTML. MQTT messages can trigger a push notification with sound.

Special edition: LongRa boards for a customer

The great benefit is that all RadioShuttle boards use the identical software, here the LongRa board with the D21 MCU, or the Eagle & ECO Power boards with ESP32 MCU, or the energy-saving Turtle board with the STM L4 MCU.

LongRa boards – special edition

Turtle and Eagle Boards used in Projects at TU Dresden

At Dresden University of Technology, Institute of Building Climatology, they are working on a precision monitoring system to measure temperature and humidity to observe the drying period for different materials.

Engineers, Makers and other parties with programming know-how are welcome to help the institute to bring this project forward. We are happy to make the contacts.
A very interesting project using our Eagle and Turtle boards.

Turtle boards used with radar movement detection

A client shared with us information about his ongoing projects with the RadioShuttle Turtle boards. He added a custom-made radar board to the Turtle board. The radar signal is amplified and arrives via ADC (analog-to-digital converter). The STM32L4 microcontroller runs an algorithm that continually computes the energy from the ADC input. By comparing the energy with the background energy, motion can be detected.

Possible applications could be motion detection in lighting environments and communication with other LoRa nodes, to inform the environment and other lights.

All has been developed by a very smart engineer who was diving into Mbed OS debugging using our RadioShuttle Turtle solution. Great work!

Maker Faire 2019 in Hannover

Also at the Maker Faire in Hannover the booth of the “LoRa Funktechnik bei Arduino-Hannover” met with lively interest. Here some impressions:

The joint stand of Arduino Hannover was the largest booth of the entire fair, and was very well attended.
Our booth “LoRa-Funktechik”, …
… where some very good conversations took place.
The presentation board is equipped with various radio modules. Starting with WiFi, two LoRa nodes, a LoRa station (as server) and a ZigBee sensor. The data is processed by a Raspberry Pi, stored in an InfluxDB and graphically displayed with Grafana in the web browser.

Recorded at Maker Fiare 2019 in Hannover.

Maker Faire 2019 in Berlin

Here are some impressions from our booth where we extensively presented the LoRa radio technology and had many interesting conversations.

The youngest maker (10 yo) who is interested in LoRa radio technology. First of all he explained to us that circuit boards can be ordered for 5 Euros in China. And he already knows a lot about other things as well. We are curious what he will do with the LoRa boards …

RadioShuttle update at year’s end

In 2018, which is now drawing to a close, we have made significant progress:

  • New ECO Power board with WiFi (based on ESP32)
  • Updated LongRa board (v 7.5, more pins, voltage measurement)
  • New RadioShuttle software 3.1 (including 18 examples)
  • Non-volatile memory for properties (“PropertyEditor” program)
  • Extensive MQTT support (MQTT-Client, RadioShuttle MQTT gateway)

We presented at the Maker Faire 2018 in Hannover, for the first time, our MQTT push server solution. It allows important events from sensors, or measurement data to be automatically transmitted via MQTT to the mobile phone via push (e.g. burglary, water leaks, failing cooling systems, temperature statistics data). The Android app is already available, the iOS app is expected for January 2019. The apps can be downloaded free of charge from the respective store.

We would like to thank all RadioShuttle users for their interest and great feedback.

Happy holidays and a happy new year 2019!
