“We are the creators of the Lemonbeat smart Device Language (LsDL). We deliver an open and generic system to easily interconnect devices with powerful, simple-to-use hard & software tools, enabling fast and cost effective development for the Internet of Things.”


A universal and flexible Lemonbeat smart Device Language (LsDL) that we have made available to the public for free to make it the standard language for the Internet of Things (IoT)


A patented Lemonbeat radio standard that offers the best mix for typical IoT applications in terms of high range, data bandwidth, low battery usage and advanced security


Firmware modules using established internet technology that make IoT devices speak and understand LsDL via Lemonbeat radio or any other common IP-oriented physical carriers

What is lemonbeat?

Lemonbeat, at its core, is a Smart Device Language. Flexible, simple and universal, it allows seamless communication between all sorts of smart things, from complex autonomous systems right down to a simple light switch – all on the same basis. Very little storage capacity needed, no need for light versions for small devices.

Independent of IP Protocol

Lemonbeat’s smart device language is independent from the transmission form and mid-layer. It can be used on any IP based stack from our own, to Ethernet, WLAN, to LoRa.

Direct device communication

Our LsDL application layer enables direct, intelligent linking of devices, reducing reliance on clouds or expensive gateways.

Reconfig during run-time

Lemonbeat devices can be completely reconfigured whilst in operation, allowing easy adjustment/optimization of device behaviour and realisation of future cases.

Lemonbeat is open

We want LsDL to become a standard language for how intelligent devices communicate. That is why the specification is free to all, and is currently being discussed by W3C as the basis for a possible standard.

Lemonbeat is secure

It offers a high level of security through encryption which is separate from the transport layer.

Interacting State Machines

Based on „out of the box“ services and device to device capability, interacting state machines can be established, enabling an intelligent and self-controlling network.

Smart Cities

We know what smart cities will require. We know that for each use case, there will be different requirements. Lemonbeat can address these.

Data will often have to be transmitted over shorter or greater ranges, many devices will have a power supply, but plenty will be battery operated thus requiring greater efficiency. Security will always be of great importance. An internet connection will not always be guaranteed.
