Controlling KNX lighting from a third-party touchscreen via HTTP, while preserving KN
#14
A small note: We have a 10-inch touch panel that we have been developing for the past 7 years for this purpose, and it has been used in dozens of projects in our country. This panel displays the visualization and Visu graphics in Logic Machine as a full-screen HMI. There is no browser-based solution here. It runs a dedicated HMI application in kiosk mode.

When the panel is first powered on, a setup wizard welcomes the user. Step by step, the wizard guides through assigning the panel IP address, entering the Logic Machine IP address, username and password, configuring the screensaver settings, and setting up alarm information and related parameters. Once all steps in the wizard are completed, the installation is finished.

After installation, the LM graphics are displayed and controlled in a full-screen experience. Access to the settings page is protected by a dedicated password. If the panel loses and regains power, it automatically reopens the graphics page—there is no need to re-enter login credentials. The panel automatically detects network errors and provides on-screen notifications. It is also possible to exit the screensaver using a password.

This is an industrial-grade IP65 touch panel solution.
