Digital Strom bridge for DALI, EnOcean and hue v2

plan44.ch Digital Strom bridge products - P44-DSB-DEH2

P44-DSB-DEH2 extends your Digital Strom system by third-party lights, buttons, sensors and actuators.

Thanks to the integrated matter bridge (currently beta), you can integrate the P44-DSB-DEH2-based lights and other devices into other personal SmartHome environments of your choice in addition to Digital Strom, and operate them via a voice assistant, for example.

P44-DSB-DEH2 uses the Digital Strom virtual device connector technology to seamlessly integrate new devices such that these become as simple to use as regular Digital Strom devices.

A single P44-DSB-DEH2 device connects to up to 64 DALI dimmable lights, many wireless buttons, sensors and actuators and Philips "hue" color LED lights

The P44-DSB-DEH2 is a cost effective way to extend a Digital Strom system for climate control (EnOcean), small office lighting (DALI), modern LED lighting of various kinds (DALI, hue), light switches that can be placed everywhere (EnOcean).
It only requires a single P44-DSB-DEH2 to connect a lot of third party devices that ideally complement Digital Strom components

The P44-DSB-DEH2 firmware can be updated by a simple press of a button to receive support for new devices, new features and general improvements.

The firmware is based on plan44.ch's modular "vdcd" and "p44mbrd" open source projects, which allows for custom modifications and extension to be implemented by plan44.ch upon request as well as by third parties.

DALI - dimmable (color) lights, simple 2-wire bus

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

P44-DSB-DEH2 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-DEH2, which acts as the DALI master.

Unlike some other DALI master devices, the P44-DSB-DEH2 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-DEH2. Please use respective Digital Strom terminal blocks or EnOcean sensors instead.

EnOcean - wireless energy harvesting devices

EnOcean is a technology for wireless, usually self powered (energy harvesting) buttons, sensors and actuators.

Adding EnOcean devices is as simple as pressing two buttons - first the learn button of the P44-DSB-DEH2, second the learn button of the EnOcean device.

The P44-DSB-DEH2 has a built-in EnOcean radio module (TCM310) to receive data from EnOcean buttons and sensors and transmit commands to EnOcean actuators like heating valves. The P44-DSB-DEH2 firmware automatically detects the EnOcean device's EEP (enocean equipment profile) to integrate different types of devices into the Digital Strom system. For example, climate related sensors and actuators will appear as blue climate Digital Strom blocks, buttons act as light switches by default but can be used for other functions as well.

Compatible EnOcean devices are available from a wide variety of manufacturers such as Eltako, Thermokon, alphaEOS, Kieback&Peter and many more

The P44-DSB-DEH2 firmware will be updated to support new profiles as needed - if a profile you need is not yet supported, please let us know.

hue - colorful LED lights, wirelessly controlled

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

P44-DSB-DEH2 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-DEH2 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.

Other device integrations supported

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-DEH2

P44-DSB-DEH2 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-DEH2 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-DEH2 but can be used on different platforms.

However, only buying the P44-DSB-DEH2 product from plan44.ch entitles you to get ready-to-use firmware updates from plan44.ch.
