EnOcean has launched the PTM 215, the first energy harvesting switch module with integrated rolling code.
This additional functionality offers data encryption for secure wireless communication in smart home systems, security access control systems and other critical applications.
In addition, EnOcean has expanded its DolphinAPI function library with new data decryption and encryption functions to enable fast and easy integration of security features in existing OEM Dolphin-based products.
The new module creates a 16-bit rolling code for each wireless telegram. The telegram header, telegram data and current rolling code in turn form the basis for generating a 24-bit message authentication code (MAC). The receiving system can use this code to check the authenticity of the data package.
The self-powered switch module harvests the energy it needs for generating the rolling code telegram and the wireless transmission with the help of the ECO 200 mechanical energy converter. The converter generates enough energy at the press of a button to enable the module to send at least two redundant wireless telegrams.
The PTM 215 is particularly suited to flat wireless switches with one or two rockers, and manual switches with up to four buttons. This allows OEMs to manufacture switches for dimmers or blind management, for example. The switch module complies with the wireless standard ISO/IEC 14543-3-10 and is available for the 868 MHz frequency band.
To enable easy integration of data decryption and encryption functions into existing products, EnOcean is also offering a new version of its DolphinAPI function library. OEMs can equip a receiver with data decryption functionality, for instance to communicate with the PTM 215.
Furthermore, the new security features of the API can be used to expand customer-specific firmware running on Dolphin modules. Here EnOcean has adopted a modular security concept. Adding data security brings an increase in energy requirements. Manufacturers can control this by combining encryption mechanisms according to the individual demands of a particular solution.
