EnOcean Pi connects energy harvesting wireless devices with the Raspberry Pi

Paul Buckley -September 13, 2013

The Raspberry Pi computer can now control gateways for energy usage and automation systems using the new EnOcean Pi accessory, available from element14.

EnOcean Pi is available in three versions: EnOcean Pi 868 MHz (Europe), EnOcean Pi 315 MHz (Japan, India, North America) and EnOcean Pi 902 MHz (North America). Costing $25.00USD the first version to launch is EnOcean Pi 868 which is available from Farnell element14 in Europe and CPC in the UK and Ireland. Versions of the EnOcean Pi supporting the 315 MHz and 902 MHz radio bands will be available in early October 2013 from Newark element14 and MCM in North America, and element14 in Asia Pacific.

EnOcean Pi is a wireless module which connects to batteryless EnOcean modules that are powered by energy converters that use mechanical motion, light or temperature differences as an energy source. This allows for maintenance-free sensor and actuator solutions that provide the necessary data for intelligent control.

Developers and OEMs can easily design low-cost gateways for embedded applications, such as smart home solutions. Instead of developing new products from scratch, developers can use the EnOcean Pi and Raspberry Pi to create a ready-made smart home box, which can process and visualise data from batteryless wireless sensors and provide central control of a wireless connected house. Other applications are gateways for cloud services or low-cost building automation with an interface to all EnOcean-based solutions.

The new Pi accessory is supplied with free to download EnOcean Link Trial Version middleware that allows users to quickly develop and integrate applications. The Raspberry Pi acts as the gateway to automate control of EnOcean-based energy harvesting wireless sensors, thermostats and switches to comfortably manage lighting, HVAC, shading and help to save energy.

EnOcean Pi also features EnOcean’s Smart Ack controller functionality, enabling bi-directional communication via radio and serial interfaces. Radio messages can be sent transparently through the serial interface in both directions to and from the Pi. EnOcean Pi can act as postmaster for up to 20 bi-directional sensors using Smart Ack technology.
