The EnOcean GmbH (proper spelling: EnOcean GmbH ), headquartered in Oberhaching near Munich was founded in 2001 as a spin- off from Siemens AG. She is the inventor and manufacturer of the patented base technology powered wireless sensors. Funding is provided by the venture capital firm Wellington Partners, SET Venture Partners, Emerald Technology Ventures, Siemens Venture Capital, Venture Capital BayTech, Siemens Technology Accelerator, Kathrein Group and Atmos Holding.

EnOcean Alliance

Various companies in Europe and North America have teamed up in April 2008 to EnOcean Alliance, a non-profit organization with the following objectives:

  • Refinement of the sensor profiles to ensure interoperability for wireless products that use free frequency bands.
  • Ensure the interoperability of products. This is based on the international standard ISO / IEC 14543-3-10.
  • Develop a wide range of interoperable wireless products to support the monitoring and control of building services.

Technology

The idea of ​​EnOcean technology based on the fact that for sending short radio signals only small amounts are needed for energy. Therefore, the transmitters use the piezoelectricity of switches ( energy harvesting ), the energy from solar cells or Peltier elements or the kinetic energy by means of electro-dynamic energy converter. This energy is sufficient to operate the transmitter battery-free, minimizing maintenance. In some applications, however, neither good lighting conditions or mechanical operations to be expected, so that in some cases batteries are used as energy source.

The radio protocol is designed to transmit information in energy with high reliability. There used in Europe the frequency of 868 MHz and 315 MHz, the frequency internationally. In March 2012, the International Electrotechnical Commission has (IEC) 14543-3-10 the EnOcean radio as an international standard ratified by ISO / IEC. The standard comprises the layers 1 to 3 of the OSI ( Open Systems Interconnection ) model, that is, the Physical, Data Link, and networking layer. The complete name of the standard is ISO / IEC 14543-3-10 Information Technology - Home Electronic Systems (HES ) - Part 3-10: Wireless Short - Packet (WSP ) protocol optimized for energy harvesting - Architecture and Lower Layer Protocol.

There is no mechanism to avoid collisions; an attempt is made not to allow this to occur only by the restriction to the smallest possible and thus short data packets. For radio modulation amplitude shift keying is used, which can be electronically implement simple and energy -saving.

Advanced security concepts such as encryption of wireless data and rolling code to prevent it, tap the data packets from EnOcean transmitters unnoticed. In addition, the sending of a data packet from the original EnOcean components using only fixed IDs allowed, so that the manipulation of an EnOcean -based system from the outside is limited. A protection against signals its own implementation of relatively simple radio standards but there is no.

In smart home applications must, for example, in older products that still do not require remote management features, all the lamps to be switched via a home automation software that can be taught in addition to the normal switch on a corresponding gateway.

The EnOcean components of the so-called Dolphin platform operate bidirectionally and offer both transmit and receive options. The devices in sensors ( switches, temperature sensors, motion detectors, light sensors, digital and analog inputs, etc. ) and actuators (relays, digital and analog outputs, dimmers, etc. ) are divided.

In contrast to other building automation technologies, an acknowledgment of receipt of a data packet in the specification is provided. Meanwhile, commercial devices are available that make it possible to determine whether a command was executed successfully.

Products

EnOcean is a development partner and supplier of energy-autonomous wireless modules ( send, receive, transceiver modules and power conversion ) for over 50 system integrators, the end products for building automation (lighting, shading, heating / air conditioning / ventilation ), the industry automation and other fields of application such as Smart Home transport and Logistics develop and manufacture.

Key partners of Enocean include companies such as Siemens, MSR Solutions GmbH Telefunken Smart Building GmbH, Viessmann Werke GmbH & Co. KG, Zumtobel, omnio, Wieland Electric, Peha, Somfy, Thermokon, Wago, Kieback & Peter, hunter direct and Eltako Electronics.

Awards

In June 2002 Enocean was awarded the Bavarian Innovation Award 2002 for its technology, most recently as Technology Pioneer 2006 by the World Economic Forum ( WEF) and in January 2007 with the seal TopJob as a top employer.
