The KNX IoT Environment sensor measures periodically the air quality. It can be used in conjunction with a KNX IoT hub running an MQTT proxy. Together it makes up a system that can cover a large area and the measurements can be conveyed over MQTT and stored at a different location.

The video shows how easy it is setup the system and how to access the data remotely. It contains the following information:

• Using the KNX IoT Environment Sensor with ETS
• Using the MQTT proxy running on the KNX IoT Hub with ETS
• Showing the measurements in ETS group monitor
• Showing the measurements on the (MQTT) dashboard, which can be accessed anywhere in the world.

In the video below, KNX IoT Devices are commissioned on Thread and KNX using an QR scanner.

The video shows the steps to commission:

• Commissioning the Device on Thread (e.g. making it part of the thread network)
• Commissioning the Device using ETS: scanning the QR info and downloading the configuration

These demos can be downloaded to the development board and used with ETS.

Demo applications for the Development board can be found here. The following demos are available:

• Colour Actuator RGB Manual
• Relay Actuator Manual
• Room Temperature Sensor Manual

These demos need additional hardware as described in the corresponding manuals.

In the video below, a setup is used that contains TP devices and IoT devices. To be more exact, on each side a button and an actuator are configured.

The configuration contains that the actuators sends feedback to the buttons.

The network/KNX topology contains an TP section and an IoT section as follows:

This setup is then configured by means of ETS 6, showing the downloading and interoperability of the TP and IoT devices in the following video:

If you are using devices communicating over Thread, then you might want to know how good the link quality is of the used communication.

In this video the LQI and RSSI metrics are explained, also the video explains how to obtain those values by using Cascoda’ Sniffer.

The post Using the Cascoda Sniffer look at the Thread link quality metrics first appeared on Cascoda: Smart Building KNX IoT Connectivity.

If you are developing devices running on Thread, then you can use Cascoda’s packet sniffer to see all the traffic in the air.

The online documentation on how to use the Sniffer is available on GitHub.

However we also made a video that demonstrates the following steps:

• Starting Wireshark, including selecting the Thread channel
• Decrypt Thread network communication (since communication over Thread is always secure)
• Showing IEEE 802.15.4 packets, Thread MLE communication
• Showing CoAP & mDNS traffic
• Decrypt KNX OSCORE messaging
• Showing & explaining the KNX s-mode messages

Just when you thought it was safe to get back in the water, after our KNX IoT Battleships game…  Cascoda’s engineers used ChiliCuisine™ to develop a lighting system all configured by ETS6 from KNX Association. Thanks to ChiliCuisine™, our low-code development environment, it only took less than a day to develop, deploy and test the whole lighting system.

The actual end user experience to configure using ETS6 and use the system with the Eink display is demonstrated in the video here:
