Your flexible, cloud-free Homematic IP® CCU smart-home-solution

---

OpenCCU-LTS (Long Term Support) is a free, alternative oparating system for the smart home central control unit CCU3 by eQ-3. The Long-Term-Support version is a stable and reliable fork of the community-driven OpenCCU project for the CCU3 hardware. The development is supported by eQ-3, but full support cannot be guaranteed.
