RWE Effizienz GmbH, owner and operator of one of Europe’s leading home automation systems, has extended access to the “Lemonbeat smart Device Language” (LsDL), a universal communications protocol for the Internet of Things, to developers and manufacturers of Internet-compatible devices in North America.
As a common language for a variety of applications, wide adoption of Lemonbeat promises to remove the interoperability barriers that have previously hampered the development of the Internet of Things. In particular, LsDL is independent from transmission methods such Ethernet, WLAN, Bluetooth, Powerline, and Thread, enabling any device to connect and interact seamlessly and autonomously with other devices, regardless of manufacturer or application. In addition, LsDL uses proven XML Internet standards and IPv6 technology to offer numerous technological advantages, including:
- Efficient, low-power operation: a patented wake-on-LAN function makes Lemonbeat the ideal solution for battery-operated devices and also allows savings in implementation costs up to 40%.
- Flexibility: LsDL supports the communication of a vast amount of devices, from simple switches-without the need for a “light” version-to complex systems and machinery.
- Future-proof connectivity: support for both mesh and star network topologies, as well as an expandable logic, allows LsDL to adapt to devices or functions that will be designed in the future.
- Security: secure encryption is handled separate from the transport layer to reliably exchange information and protect privacy across connected networks.
“A common communication concept is the key to speeding up innovation within the IoT industry and promoting the proliferation of devices” said Holger Wellner, managing director of Lemonbeat GmbH, a new company set up by RWE to push the solution. “We have taken advantage of our technological edge as the market leader in Germany to develop Lemonbeat. The next step is standardization of the design language, which we believe will more quickly and cheaply usher in the products and services that will make up a network of distributed and linked intelligence.”
Industry Standardization and Adoption
In September, RWE presented comprehensive information on LsDL with the World Wide Web Consortium (W3C) and formally submitted a specification draft for the Lemonbeat Application Layer. Lemonbeat is currently at W3C for review and comment in the “Web of Things” Interest Group.
Recognizing the opportunity presented by Lemonbeat, the first pilot customers already are showcasing prototype products that demonstrate how devices can be connected with each other using Lemonbeat. For example, Gardena, part of the Husqvarna Group and known for innovative gardening tools and watering systems, plans to introduce the first robot lawnmowers that “speak” Lemonbeat onto the market next year.
Developers and manufacturers in North America can now use the Lemonbeat smart Device Language to integrate core communication services into edge devices. Products destined for the European market can also leverage the Lemonbeat Radio (868 MHz) and Lemonbeat Chip, a System in Package that combines processor and transceiver to allow the swift implementation of Lemonbeat with full support for networking and wireless connectivity. Further products are expected to follow, including the Lemonbeat Radio and Chip adapted for the North America market and a development kit that will allow users to create Lemonbeat devices in a matter of days.
