History

nymea began as a passion project by a small team of developers in Vienna, Austria who wanted to build a smart home system that was truly local-first — no cloud, no vendor lock-in, just open software running on a device in your home.

2013 — The idea

The founders identified a fundamental problem in home automation: every platform required a cloud connection, every device vendor had its own silo, and there were no open standards that let different systems work together. The goal was to build a middleware layer that solved this — a single, open-source daemon that could talk to anything and expose a clean, consistent API.

2016 — guh GmbH

After years of development the project was mature enough to take to market. guh GmbH was founded in Vienna to provide the nymea platform commercially, offering the integration middleware together with tooling and support for IoT product manufacturers. The company was named after the original internal project codename; the platform itself was already called nymea.

2019 — StreamUnlimited partnership

In September 2019 StreamUnlimited, an Austrian audio and streaming technology company, integrated nymea into its StreamSDK. This gave nymea a presence in a broad range of connected audio and consumer electronics products and validated the platform as production-ready middleware for hardware manufacturers. Around this time guh GmbH was renamed to nymea GmbH to align the company name with the platform.

2024 — Acquisition by chargebyte

On 15 January 2024 chargebyte GmbH, a German specialist in charging station communication technology, acquired nymea GmbH. The acquisition brought nymea’s integration platform into the energy sector: a modern EV charging station has enough compute to run energy management locally, and nymea’s wide integration list — PV inverters, battery storage, heat pumps, household appliances — made it a natural fit. Following the acquisition nymea GmbH was renamed to chargebyte austria GmbH. Development of the open-source nymea platform continues under chargebyte stewardship.
