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.
OpenCCU-LTS is intended exclusively for use with CCU3 or ELV Charly.
For use on other hardware or platforms, please use the upstream OpenCCU releases.
