Homematic HCU connects your Home Control Unit to Homey through eQ-3’s own **Connect API** – the interface Homematic IP provides for plugins. Everything stays in your home network.

**Why the HCU route**

- **Official and documented** – built on the Connect API, not on reverse-engineered cloud calls. There’s a specification to build against, so behavior doesn’t depend on guesswork.
- **Local** – Homey talks directly to your HCU over your LAN. No cloud account in the middle, and your devices respond even when the internet is down.
- **Real time** – state changes arrive instantly via WebSocket.
- **Made for the current platform** – the HCU is eQ-3’s central unit going forward, so the app grows with it.

**What works today**  
Switches and sockets (with power/energy for sockets), dimmers, thermostats, motion and climate sensors, door/window contacts, shutters and blinds, wall remotes/buttons, and HCU groups. Plus a one-screen quick start: enter the activation key, press one button, done.

**Coming next (planned, no promises on dates)**

- Smoke detectors, water sensors and alarm sirens
- Presence detectors and power/energy metering for switch actuators
- RGBW controllers, wired DIN-rail actuators and floor heating actuators
- Garage doors and door locks
- A built-in “report unsupported devices” button, so missing devices can be added quickly (it only shares model, type and channels, never names or serial numbers, and sends nothing automatically)

**Good to know:** devices are paired in the Homematic IP app first, then added in Homey. Requires a Home Control Unit with developer mode (official Homematic HCU Plugin on the way, stay tuned!). This is a community app, not an official app from eQ-3.

Feedback and device requests are very welcome.
