New software looks to opens door to energy harvesting wireless technology

EnOcean Link from EnOcean is the first middleware for energy harvesting wireless technology. According to the EnOcean OEMs will now be able to integrate EnOcean technology easier and faster into a wider range of applications and systems, such as those in smart homes. The software provides a universal interface for wireless communication and automatically interprets information from EnOcean telegrams.

As a result, sensor data such as moisture or temperature is prepared so that different devices, servers and even cloud services can process it immediately. OEMs can obtain EnOcean Link directly from EnOcean as licensed software.

EnOcean Link converts the bits and bytes of an EnOcean telegram directly into data values. In doing so, the middleware automatically takes into account all specifications of the EnOcean protocol stack and the EnOcean Equipment Profiles (EEPs) of the EnOcean Alliance as well as encryption mechanisms. This means EnOcean Link provides all wireless applications with a ready-made key to the energy harvesting wireless world. Since the software interprets all data, it also ensures the interoperability of equipment from different manufacturers.

The use of EnOcean Link will save development resources and significantly quicken the time-to-market for energy harvesting wireless applications. Instead of developing their own software for a particular application in order to interpret the communication protocol of the energy harvesting wireless technology, OEMs can use the finished middleware for this purpose immediately. The same applies to any application that integrates or further processes the energy harvesting wireless technology as well as to each EnOcean radio frequency.

“Our gateway solutions combine energy-consuming and -generating units interactively in a building. Thereby, the seamless communication between different protocols is an important requirement,” says Wolfgang Luth, Head of Sales & Marketing Smart Home, Diehl AKO Stiftung & Co. KG. “EnOcean Link provides the tool by which our gateways can integrate the EnOcean wireless standard into each network – just Plug&Play. We save developing effort due to the middleware and can immediately provide batteryless wireless communication as a key function of our solution.”

Manufacturers can now focus all their attention on the application and their core activities. At the same time, EnOcean Link makes it easier to implement powerful energy harvesting wireless networks, which are required by comprehensive smart home and M2M systems. EnOcean will update EnOcean Link continuously. With the purchase of the licensed software, OEMs will receive all updates within the first year free of charge. Afterwards, they can extend this service, including the related support, by entering into a maintenance agreement. EnOcean also offers a one-day training course on EnOcean Link.

In a smart home application, for example, a gateway can use EnOcean Link to immediately interpret the information from energy harvesting wireless sensors, including temperature, occupancy and light intensity, and forward this information to a central building control system. It does not matter if the system is networked with BACnet, KNX, Z-Wave, ZigBee, Bluetooth low energy or other automation protocols.

Along with EnOcean Link, EnOcean has also added Decoding Gateway to its software portfolio. This solution is specifically aimed at manufacturers who want to integrate data encryption into their applications quickly and easily. The firmware adds an important component for the receiving side to EnOcean”s security portfolio. When the PTM 215 energy harvesting wireless switch module transmits encrypted telegrams with rolling code based on the AES 128 standard, the TCM 300 transceiver module – programmed with Decoding Gateway – can decrypt these telegrams and then forward them to an external controller for immediate use.

Security functions can be easily added to existing receiving and gateway products by programming the TCM 300 transceiver module with Decoding Gateway. During the programming process, the firmware stores the rolling code together with the corresponding key on the Dolphin chip, so that no changes need to be made to the hardware. Alternatively, OEMs can also store this information on a separate EEPROM, especially for new product developments. The security information is therefore stored outside the module”s program memory.
