Firmware 2.6.9

Firmware 2.6.9 for P44-DSB devices is a maintenance release for firmware release 2.6.

Note that this update is always needed as an intermediary step to firmware 2.7.0 and beyond. So, please check for new firmware again after installing this version, there might be a newer firmware already.

General Recommendation for updates: before updating, please always use the "Download configuration backup" button to download a backup of your device's configuration.

Changes since production version 2.6.8

The only change in 2.6.9 is as follows:

  • There is a new feature allowing you to enable receiving public beta firmware for your P44-DSB device. While beta versions have been available upon request for a long time already, you can now opt-in (and opt-out later, of course) from the web interface. There is a new button labelled "Beta..." besides the "Check for new firmware version..." to open a dialog for enabling or disabling receiving betas.
  • The reason for adding this option is that on one hand, there was a lot of work going into the development of the P44-DSB device firmware in the past year, in particular for matter bridging and a built-in p44script IDE. On the other hand, matter bridging is not yet certified, and will be included in a general release only later. So you can now decide yourselves if you want to use the new features right now in the public beta releases (which are usually as stable as regular releases) or wait for a later general release.
  • If you want to first have a look at what has happened in the betas since the 2.6.8 release, you can read it up in the beta release notes.

Changes since production version 2.6.6


  • local click handling: local click handling acts as a fallback when no connection to dSS exists, and makes all lights respond to light buttons. Fixed a bug that also made lights respond to non-light buttons in this case.
  • Animators: fixed bug that caused spurious glitches (animators seemingly not running or running too fast)
  • upgrading: ready for upgrading to 2.7.0 and beyond. Installing 2.6.9 is required as an intermediate step in all cases. Please check for updates again after installing.


  • Enocean: add support for D2-07-00 door lock status profile.
  • Channel transitions: improved wraparound channels (such as "hue") to allow full circle transitions in one step.
  • Analogio: Added CWWW lights, add WebUI support for creating Linux-PWMChip-based lights.
  • p44lrgraphics: add support for multiple fonts, for now 7x5 and 8x5 but mechanism in place for bigger sizes, add support for french accent characters with basic mechanism in place for handling any UTF-8 codepoint in fonts.
  • p44script: added foreach statement
  • p44script: answer() functions for web requests and feature requests now also accept an error value as argument to send back to the API caller.
  • p44script: Added digitalbus() to combine multiple GPIOs to input or output a digital value
  • p44script: all time getter functions such as hour(), month(), sunrise() etc. now accept a epoch timestamp argument. Also epochtime() function allows constructing epoch timestamps from date components.
  • LED chains: more led layout (R,G,B,W ordering) options
  • LED chains: reworked update timing engine, is now more precise, issues log warnings when display is likely to be jumpy or flickering due to limits in max LED output frame rate.
