Products for Digital Strom, matter and Standalone Automation Solutions
Controllers for custom LED + automation projects
Building on the proven automation platform for the plan44 standard products P44-DSB and P44-LC, specialized hardware variants provide more flexibility and functionality for realizing projects, such as complex LED installations, electromechanical Objects etc. These are available upon request, such as the P44-AC-UNI or P44-xx-LED.
Due to the great flexibility of the built-in script language p44script, even complex installations can be realized completely in the device, entirely without dependencies on external services, tools, development environments etc. The device can run completely autonomously, can be easily replaced in case of defects, and is thus suitable for long-lived installations.P44 Automation Platform - Common Features
- Basic functionality of the P44-LC/-DSB as a home automation controller, with rooms, scenes, dimmable and colored lights, pushbuttons, sensors, etc.
- P44-xx-LED with 4 ports for addressable smart LEDs (WS281x) with up to 1000 LEDs per port. With the graphics subsystem p44lrgraphics various animations can be programmed on LED chains and areas.
- P44-xx-DCM, P44-MC-E+DC, P44-AC-UNI have connections for DC motors, including limit switches and/or current measurement for detecting end stops.
- P44-AC-UNI has various inputs and outputs, optionally optically isolated, optionally with power FETs etc., a 0-10V analogue output and a real-time clock for precise, internet-independent time.
- Thanks to the integrated matter bridge (currently beta), installations based on P44-LC/-AC can be integrated into matter-enabled SmartHome environments. This means that even highly customised products can easily become part of a modern SmartHome and trigger effects on demand via voice assistant, for example.
- MIDI via USB and RTP-MIDI support allows integration with sound projects and control via a wide range of available MIDI controllers.
- All special hardware variants are also available as P44-DSB version and can seamlessly fit into a Digital Strom installation. As P44-LC/AC version they function independently.
- The firmware of all P44-DSB, P44-LC and P44-AC is identical for the entire product range. All products always have the latest firmware available. Thus, the special hardware variants can also benefit from the general further development of the firmware.
- P44-LC products are remotely maintainable on request - temporary or permanent web links can be set up for access.
- Flexibly extensible - with the built-in scripting language p44script, almost any additional functionality can be easily created:
- Scene scripts that are executed when a scene is called (e.g. for special transitions/effects)
- Triggers and Evaluator Actions that are executed when certain conditions (timing, sensor values, inputs) occur.
- The Mainscript, which can be the "main program" that takes complete control, or just defines some "handlers" that respond to certain events (e.g. network communication, input signals, time or sun position, periodic triggers, etc.)
- With Scripted Custom Devices also lights, buttons, sensors, inputs can be implemented in p44script, which can be used afterwards with standard behavior, e.g. in scenes.
- All scripts are part of the device configuration, and can be saved and restored together with it as backup, and remain intact during firmware updates.
- p44script can be created, edited and debugged (breakpoints, singlestep, inspection, etc.) with the built-in IDE (Integrated Development Environment) via the web interface.
- Individual p44script commands can be tried out in the IDE's playground area or in the console, to test effects and sequences and view variables.
- A quick reference to the scripting language is built into the device (and therefore always available offline), more detailed documentation with examples is available online.

Open Source - the basis of all plan44.ch products
The functionality of these products is implemented in plan44.ch's "vdcd" virtual device connector daemon open source project. If you are experienced with building Linux software, you can compile your own versions of vdcd in a OpenWrt build environment.
The vdcd project on github contains documentation describing how to build and run vdcd on Linux
