About Us

Lemonbeat GmbH, based in Dortmund, Germany, was established in October 2015, and is a 100% subsiduary of innogy SE (RWE Group) — one of Europe’s largest utility companies. That means, energy is part of our DNA.

Key to  our cross-industry IoT offerings is Lemonbeat OS.  Lemonbeat OS is an IoT-tailored Operating System, made of standardized building blocks that can be combined and recombined to fulfill functionalities of any imaginable IoT use case. Since these building blocks get implemented directly into devices, Lemonbeat OS gives intelligence back to them. Lemonbeat OS can be used in combination with common cable or wireless IP-based communication protocols.

As a company we are part of the following organisations:
