Appearance

Version 2.8.8 ​

13. July 2026

Added ​

  • App/UI: Full support for KNX RGBW lights – colour and white channel controlled via a combined colour wheel
  • Backend: free@home radiator thermostats and push-button sensors (rockers) are now detected and can be added
  • Backend: New KNX datapoint types for colour and tunable-white luminaires – RGBW (DPT 251.600), colour xyY (242.600), colour temperature (7.600) as well as 243.600, 249.600 and 250.600
  • Backend: New KNX "RGBW" light profile

Changes ​

  • App/UI: Background image upload is now available on Android devices
  • App/UI: Background image upload no longer has a size limit – images are automatically scaled to an optimal resolution and file size (previously max. 3 MB)
  • Backend: Improved simulated feedback handling
  • Config/UI: Device profile editor optimized – editing sub-profiles (components) no longer shows spurious required-field validation errors
  • Config/UI: Multimedia devices can now be customized in the "Display" tab (element visibility, naming and order); elements the app renders as a combined media widget are hidden
  • NodeRED: Upgraded to version 5.0.1

Fixed ​

  • App/UI: A missing thermostat setpoint is no longer shown as "NaN" or "0", but as "–".
  • App/UI: After the controller's IP changes (e.g. via DHCP), the app automatically finds the new local address again and reconnects directly, instead of staying on remote access.
  • App/UI: After removing a background image, the colored theme gradient is shown again after an app restart instead of a dark background.
  • App/UI: Connecting to older nomos controllers is possible again
  • App/UI: Scrolling in the right sidebar works again.
  • App/UI: The colored stripe at the top of the mobile menu again shows the accent color for color themes instead of the default gradient.
  • App/UI: The thermostat mode selector is hidden when only a single mode is selectable.
  • Backend: Certain free@home device types were skipped during device detection
  • Backend: General stability improvements
  • Config/UI: In the network settings the second DNS server field no longer briefly shows "undefined" when the controller reports no or only a single DNS address.
