Smart Home Stack (Homematic · RPI-RF-MOD · debmatic)

Use case

Heating, lighting, door/window sensors in six rooms are addressed via a Raspberry Pi with RPI-RF-MOD and debmatic. A small REST API wraps the devices for automation, a Grafana floorplan shows status per room, authentication sits behind the forward-auth SSO on my own reverse proxy.

What's done so far

• Backend abstraction HomematicBackend ABC with two implementations
• CloudBackend via homematicip-rest-api Python library
• LocalBackend via XML-RPC and ReGa HMScript — fully internet-independent
• Three containers in concert: a collector (polling + DB write), a FastAPI-based REST service layer (pure DB service), and rule-based automation for valve control on a 60-second tick
• Open-Meteo integration for DWD weather data as an external input
• Schema home in the shared monitoring DB on TimescaleDB
• Grafana dashboard with HTML text panels and JavaScript (floorplan)
• Boost command queue through the API; automation bypasses the queue for direct valve updates

In progress

Not much — the stack is stable in daily use. Focus is on maintenance, occasionally adding new sensors, and small improvements to the floorplan and automation rules.
