EnOcean Alliance is a consortium of companies in North America and Europe that are developing and promoting self-powered wireless devices. The initial consortium formed in 2008, and includes Texas Instruments, Omnio, Sylvania, Masco, and MK Electric. The consortium claims the largest installed base of wireless building automation networks.

The main objective of this technology is to allow sensors and radio switches to operate without batteries reducing maintenance. To do this the technology uses energy harvesting which exploits slight changes in motion, pressure, light, temperature, or vibration to transform small energy fluctuations into usable electrical energy. The devices transmit at 120 Kbits per second, up to 300 meters with a data packet of 14 bytes. The transmission frequency used for these devices is 868.3 MHz, an unlicensed radio frequency.

EnOcean GmbH, a spin-off company of Siemens, supplies the transmitters, receivers, transceivers and energy converters to companies such as Distech Controls, Zumtobel, Omnio, Osram, Wieland Electric, Peha, Ther- mokon, Wago, Herga and MK Electric, who then develop and manufacture products. While the products tend to focus on building automation they are also targeted for industrial automation and automotive markets.

EnOcean is based on an international standard, the International Electrotechnical Commission (IEC) standard—ISO/IEC 14543-3-10—for wireless applications with ultra-low power consumption. They have created EnOcean Equipment Profiles (EEP) for EnOcean devices that ensure interoperability of different end-products based on EnOcean technology; resulting in equipment from one manufacturer being able to communicate with equipment of another manufacturer.
