The Benefits of KEO in Detail
Five reasons why market leaders in heat pumps, wall boxes, solar and energy management rely on KEO.
30 days to proof of concept
While in-house development often takes months and ties up an entire development team, we deliver a working PoC on your platform within 30 days. You can test and validate the integration in your own environment before making a long-term commitment.
gridX confirms: “A fast and compliant market launch.”
Over 2.5 million connected devices worldwide
Our software is already used in products from market leaders in the heat pump-, wallbox-, solar-, energy management-, and energy storage sectors. This means you’re relying on a solution that has been proven millions of times in the field—no trial-and-error phase, but mass-market quality from day one.
Over 20 years of device and software development
KEO is a spin-off of the Kellendonk Group, which has been developing hardware and software for the mass market since the 1990s—in the fields of heating, home appliances, and industrial automation. This experience in developing durable, robust solutions is reflected in every KEO product.
TQ confirms: “Significantly faster in implementing use cases.”
Active Participation in EEBUS e.V.
We don’t wait for the next standard—we help shape it. As an active member of EEBUS e.V., we learn about upcoming changes early on and proactively adapt our software stacks.

What EEBUS’s in-house development actually means
EEBUS is the European standard for communication between energy-related devices. It is shaped and continuously refined by more than 70 companies within EEBUS e.V. What at first glance appears to be a clearly defined standard turns out, in practice, to be a highly complex endeavor.
KEO has already gone down this path—with over 20 years of experience and more than 2.5 million devices in the field. You don’t have to.
