KNX IoT explained at Light + Building 2022
Thanks to the KNXnet/IP protocol, KNX has been capable of using IP networks to communicate between devices, as well as between servers and clients. Expanding into the IoT world with KNX IoT however, qualitatively increases interoperability at IP level, making KNX the largest ecosystem in the building control market. By adding new physical layers (mesh networks) demanded by the market, and becoming software-development-friendly, KNX IoT has become accessible and more attractive to IT companies and software developers. With the availability of an open-source stack, developed by Cascoda, for KNX devices communicating on IPv6 networks, and a corresponding ETS app for configuring virtual KNX IoT Point API devices. Developers can now use the open-source stack, which is freely available on GitLab: https://about.gitlab.com/
Energy Management with KNX explained at Light + Building 2022
To understand just how powerful and all-encompassing KNX is, the Energy Management panel at the KNX Booth showed an enormous diversity of applications that KNX can handle, including multimedia, audio, intercom, access control, cameras, alarm systems, fire protection, lighting, shading, fault detection, voice control, HVAC, coupling with other systems such as IR, and, of course, energy management with connection to charging stations, solar inverters, storage devices and meters. For metering, there are devices for either direct or indirect coupling. There are also solutions for solar inverters that can monitor production. You can use metering to find out what your general consumption is, but you can also have a submeter in a particular zone, or you can monitor at the level of a circuit. These systems have to be connected to central intelligence with logic. https://sustainabilityknx.org/
KNX Secure explained at Light + Building 2022
KNX Secure is designed to prevent attacks on the digital infrastructure of buildings, and there are currently more than 400 KNX Secure devices that are certified for conformity to AES128 authentication and encryption mechanisms. Furthermore, this year KNX Secure received the ‘Information security tested Smart Home and Building’ certification from the VDE, which confirms that the security standard protocols are correctly applied. Within a KNX installation, KNX Data Secure relates to telegrams sent between KNX devices over any line type. For systems that are connected over a local area network using KNXnet/IP, KNX IP Secure adds an extra layer of security. If you wish to communicate over the Internet with your installation using KNXnet/IP, you should continue to use a VPN connection, in spite of the fact that, for example, a KNXnet/IP Secure tunneling interface will allow you to also authenticate yourself with a password. https://secure.knx.org/
