DALI is a mature and widely used industry standard (IEC 62386) for lighting devices.

P44-DSB-D brings the simplicity of Digital Strom's plug and play concept to the growing range of DALI enabled lights - LED power supplies and fluorescent tube ballasts likewise.
Just connect them to the bus and these lamps become part of the Digital Strom system.

Up to 64 DALI slave devices can be connected to a two wire bus. The bus is powered and controlled by the P44-DSB-D, which acts as the DALI master.

Unlike some other DALI master devices, the P44-DSB-D does not need any manual configuration of DALI devices, but automatically detects all devices connected, and makes them available as Digital Strom compatible lights.

The device works with preconfigured DALI devices (existing short addresses) or new unconfigured devices from factory. Bus address collisions can be resolved via the web interface.

Compatible DALI devices are available from many vendors, including Unidim, Osram, Tridonic, TCI, Meanwell, TCI, Helvar and many more.

DALI control gear (e.g. presence detectors or illumination sensors) is not supported and can interfere with operation of the P44-DSB-D. Please use respective Digital Strom terminal blocks or EnOcean sensors instead.

Currently supported DALI profiles:

"hue" lights are colored LED lights from Philips/Signify, which can be wirelessly controlled via smartphone apps and third party software

P44-DSB-D makes hue lights become part of your Digital Strom light scenes. Create your multi-colored light scenes, then recall them by simply pressing the light switch.

The P44-DSB-D automatically detects and connects to the "hue" bridge by press of a button. Once connected, all hue lights appear as Digital Strom (yellow) light devices. All normal hue functionality remains unaffected, you can still control the lights via hue mobile app, the hue cloud and third party apps. The monochrome hue "lux" and tunable white "ambient" lights are also supported.

Currently supported hue profiles:

P44 devices support a lot of other device integrations thanks to the powerful built-in p44script scriping language.

With Scripted devices, integrating third-party SmartHome devices for example via HTTP/REST APIs, modbus, or plain TCP/UDP socket connections can be done with a few lines of p44script. Project-specific versions of the P44-xx devices have additional hardware capabilities, such as SmartLED data outputs, analog/digital I/O, DC motor drivers etc. which can all be leveraged to create fully integrated devices with standard Digital Strom light/color/shade/sensor behaviours as needed.

Open Source - the basis of P44-DSB-D

P44-DSB-D is based on plan44.ch's "vdcd" virtual device connector daemon and "p44mbrd" plan44 matter bridge daemon open source projects, as well as the OpenWrt embedded Linux platform. Being based on open source, the P44-DSB-D allows third parties to contribute features and build their own versions for experiments and support of new hardware. "vdcd" and "p44mbrd" are not restricted to run on the P44-DSB-D but can be used on different platforms.

However, only buying the P44-DSB-D product from plan44.ch entitles you to get ready-to-use firmware updates from plan44.ch.
