Cooperation for matter certification of the P44 units


For the certification of the Matter Bridge component, plan44 was able to enter into a cooperation with the company Becker-Antriebe, a renowned German manufacturer of roller shutter and sun protection drives.

Since on both sides the interfaces to the respective systems were already future-proof and modularly designed, the Matter connection can now be elegantly implemented in a joint open source project based on the plan44 Matter Bridge application.

In this way, the concrete experiences of plan44 with the Matter SDK and the beta test with the Matter connection of the P44 products, which has already been running for several months, are efficiently combined with the abilities of a larger company in the area of organisation and implementation of certification.

Work on the joint project is already in full progress, and it is foreseeable that certification can be carried out in a few months already. In the meantime, the Matter beta software for the P44 devices will of course be continuously improved and will continue to be available to interested plan44 customers.

Support documentation


Online for a while, but still (too) little known: the support documentation for installers and everyone who works with P44 DSB units.

Despite the variety of possible devices, the integration of DALI+EnOcean devices with P44-DSB/P44-LC is generally quite simple and works with little configuration.

Nevertheless, there is no such thing as technology without problems, and especially with DALI there are very different DALI drivers that require a little more care depending on the situation, to ensure that everything works properly.

To make sure that installations and support cases can be solved as quickly and well as possible, there has been a detailed section on installation and support in the Technical Documentation since the end of 2022.

You will find a lot of help and answers to questions that sometimes arise during installation, commissioning and maintenance, e.g.

  • Tips on selecting DALI devices (topic: unique identification)
  • Safe procedures for troubleshooting and for adding DALI to existing installations
  • Radio range and external antennas for EnOcean
  • Logs, loglevels, focusing on a problematic device
  • Remote maintenance from P44-DSB/P44-LC directly to the unit without going via dSS
  • Checklist for efficient support requests to plan44
  • etc.

I am also happy to receive tips from the field on what is perhaps still missing or should be described better. Otherwise, I hope this documentation helps you with new and existing projects with P44-DSB and P44-LC devices!

Happy New Year!


Thank you for your trust in the P44 products, your feedback, your ideas for new features and sometimes your patience in solving problems! 2023 will be an exciting year for the SmartHome, I hope you will continue to be part of it!

Many things will be exciting in 2023 - certainly including seeing where the text and image AIs that became widely available at the end of 2022 will take us. The image for this text, for example, was created by Midjourney with the prompt "The future and power of open source standards, abstract, geometric, calm, clean smart tech look, many joyful colours ".

For the SmartHome, 2023 will be exciting to see the adoption of matter. Although this new standard was already published in October 2022 and many manufacturers have shown or announced devices, there is still very little on the market.

So there were probably hardly any matter gadgets under the tree, even for smart home fans...

But if you have a P44-DSB or P44-LC, you can already try it out now as a beta. Or if you like to do some tinkering over the holidays, likewise - the do-it-yourself LED torch from last year or other LED setups become a matter bridge with the new beta SD card image for P44-DSB-X or P44-LC-X standalone controller. With this, you can already say "Hey Siri, switch on the torch", and much more, see Youtube-Video...

Soon in 2023, however, things should really get going with matter, when many of the announced products and updates actually become available.

For the installation industry, matter opens up above all a new long-term opportunity: Smarthome-capable infrastructure!

Because matter is to the smarthome what the power socket was to electrification 100 years ago - a standard so that the building-side infrastructure can be connected to (and disconnected from) the customer-side devices in a simple way.

If matter-enabled devices (such as P44-LC-DE) are installed in a fixed installation, the future users can determine the mobile part of the smarthome themselves and bring it along with them. Whether they prefer to use Alexa or Siri, have chosen iPhones or Android, Apple or Samsung, or even use a combination of everything - it no longer makes any difference.

What also makes matter special: the software is open source. Not only big companies, but also small ones like plan44 can join in (there are still problems in the area of certification, which will hopefully get more attention in 2023).

In this sense - a happy new year - in which we will hopefully see a lot of the illustrative "future and power of open source standards", not only in the SmartHome!

Interview with plan44 at


Frank-Oliver Grün interviews me about opportunities and problems with matter for a micro company like plan44

The questions revolve around technology and product development, but also in particular around the certification of matter devices developed in micro companies and/or arising from open source projects.

Playing with matter-beta on devices


A short Youtube video showing what already works with the current beta firmware for P44-DSB devices with matter, DALI, hue, SmartLEDs and digitalSTROM.

matter and P44 devices


What is "matter" and what does it mean for users of plan44 devices?

This week the new SmartHome standard matter was published.

What it is all about and what it means for users of P44-DSB and P44-LC devices is explained on the new matter page at

Tutorial: Dynamic color scenes with P44-DSB / P44-LC


The P44-DSB / P44-LC "scene scripts" can be used to create dynamic scenes for any CW/WW or color luminaire, whether DALI, hue or SmartLEDs.

In the "Tutorial" section of the plan44 TechDoku there are now two new directly applicable examples for this:

Newly opened: the community forum


The community forum aims to exchange questions, answers, ideas, projects with and around the the P44 products and OpenSource, and to complement the support.

The forum has its own RSS feed, which can be subscribed to separately besides this general Plan44 news feed with the link

Tutorial: DIY LED-torch with Rpi+P44-xx-X


In the new "Tutorial" section there is now a detailed guide how to create a "torch" using the free P44-DSB-X or P44-DSB-LC on a RaspberryPi connected to a WS281x SmartLED strip

The tutorial section is part of the "plan44 tech docs", where you can find a lot of advanced information about the P44-DSB and P44-LC devices, especially about the possibilities offered by the built-in scripting language 'p44script'.

The instructions for building the "Torch" explain step by step with pictures and videos how to build the decorative "Torch" - but also show the basics of working with SmartLEDs and P44-LC/DSB, which can also be used for other projects.

Go to the "Torch" construction manual:
