OpenCCU (formerly RaspberryMatic) is a free, Buildroot-based open-source operating system that turns CCU3/ELV-Charly hardware, Raspberry Pi and other SBCs, or virtual appliances into a cloud-free Homematic IP smart-home hub. It is 100% compatible with eQ-3's CCU3 central control unit and can run under Proxmox, Home Assistant, Docker/LXC, Kubernetes, and other hypervisors.
Use cases
- run a cloud-free homematic IP smart home hub
- replace a CCU3 with a Raspberry Pi
- run Homematic CCU as a virtual appliance in Proxmox or Docker
- self-hosted home automation central control unit
- flash an open-source OS onto ELV Charly or CCU3
- control HomeMatic devices without the cloud
When to choose
- you use Homematic IP/HomeMatic devices and want full local control without cloud dependency
- you want a CCU3-compatible hub on cheaper generic hardware or a VM
- you prefer a community-driven, open-source smart-home central unit
When to avoid
- you use non-Homematic smart-home protocols like Zigbee or Z-Wave exclusively
- you want a hub with built-in cloud integrations or voice assistants
- you need a general-purpose home automation platform rather than a Homematic CCU replacement
