Enocean
Enocean refers to a manufacturer-independent standard for battery-free wireless sensors that is used primarily in the monitoring and control of house and building technology.
It differs from other wireless sensor systems used in building automation , such as B. Z-Wave mainly because of its very low energy consumption. This supports the principle of “ energy harvesting ”, in which the sensors and switches work largely self-sufficient in energy and draw their energy from the immediate environment (movement, light, temperature differences). The Enocean radio was introduced in 2012 in the international standard 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 protocols). regulated. The initiator of the standard as well as the inventor of the basic technology and holder of the corresponding patents is EnOcean GmbH , Oberhaching , founded in 2001 , a spin-off from Siemens AG financed by venture capital . To further develop Enocean technology, the company and partners from the building industry founded the non-profit organization Enocean Alliance in April 2008 , an association of now more than 400 companies. The Enocean Alliance is based in San Ramon, USA. In Germany, the Enocean technology is sold by some providers of single-family homes under their own brand names. a. as Weberlogic from Weberhaus and as Wohnen 2.0 from Viebrockhaus .
technology
The idea behind Enocean technology is based on the fact that only small amounts of energy are required to send short radio signals . The transmitters therefore originally used the piezoelectricity of switches ( energy harvesting ), the energy of solar cells or Peltier elements and the kinetic energy by means of electrodynamic energy converters . This energy is sufficient to operate the transmitter without batteries and thus with little maintenance. In some applications, however, neither good lighting conditions nor mechanical actuation are to be expected, so that in rare cases batteries are also used as an energy source.
The radio protocol is designed to transmit information with low energy and high reliability. In Europe, the frequency 868.3 MHz (according to R & TTE specification EN 300220), in Japan the frequency 928 MHz and in North America the frequency 902 MHz (ISO / IEC 14543-3-11) are used. In March 2012, the International Electrotechnical Commission (IEC) ratified EnOcean radio as an international standard with ISO / IEC 14543-3-10. The standard comprises layers 1 to 3 of the OSI (Open Systems Interconnection) model, i.e. the physical, data link and networking layer. The full 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 Protocols. The radio range is up to 300 m in open areas or up to 30 m in buildings and the data throughput is 125 kbit / s.
There is no mechanism to avoid collisions; An attempt is made to prevent this from occurring in the first place by restricting the data packets to the smallest possible and therefore short. Amplitude shift keying is used for radio modulation and can be implemented electronically in a simple and energy-saving manner.
Extended security concepts such as encryption of radio data and rolling code prevent data packets from being tapped from Enocean transmitters unnoticed. In addition, the sending of a data packet from the original Enocean components is only permitted using fixed 32-bit IDs, so that manipulation of an Enocean-supported system from outside is only possible to a limited extent. However, there is no protection against signals from your own implementation of the relatively simple radio standard.
In smart home applications, for example, with older products that still do not have remote management functions, all lamps that are to be switched via home automation software must be taught in to a corresponding gateway in addition to the normal switch.
The components of the Enocean platform work bidirectionally and offer both sending and receiving options. The devices are divided into sensors ( switches , temperature sensors , motion detectors , brightness sensors , digital and analog inputs etc.) and actuators ( relays , digital and analog outputs, dimmers etc.).
In contrast to some other building automation technologies , confirmation of the receipt of a data packet is provided in the specification. Commercial devices are now also available that enable the determination of whether a control command has been carried out successfully.
Products
Enocean is a development partner and supplier of energy self-sufficient radio modules (transmitter, receiver, transceiver modules and energy converters ) for over 350 product manufacturers, the end products and systems for the digitization of buildings and building services, building automation ( lighting , shading , heating / air conditioning / ventilation ), develop and manufacture industrial automation as well as for other fields of application such as smart home, transport and logistics.

Home automation software with Enocean support
Common home automation software based on Enocean are the MyHomeControl systems from BootUp GmbH, Remigen , Switzerland, as well as the BSC-BoSe from BSC Computer GmbH, Allendorf (Eder), which is also offered in various OEM versions (including Eltako GVS and OPUS Vitoo ) . In addition, the company Jäger Direkt enables the connection of Enocean-based devices to Apple HomeKit ™ with its OPUS Smart Home Gateway (based on the Smart EnOcean Gateway from Digital Concepts). Furthermore, the software projects FHEM and ago control available under a GPL license support the Enocean protocol.
Awards
In June 2002 the company was awarded the Bavarian Innovation Prize 2002 for its technology, most recently as Technology Pioneer 2006 of the World Economic Forum (WEF) and in January 2007 with the TopJob seal of approval as a top employer.
