How it works

  1. Connect to your KNX IP gateway (KNXnet/IP tunneling).
  2. Add rooms and devices, enter the KNX group addresses.
  3. Done – the app remembers everything locally on your device.

Handling

Operating mode (default)

The app always starts here. Only controls are visible – no editing, no deleting, no adding. Accidental configuration changes are impossible.

Configuration mode

Activated via Settings → "Edit configuration". An orange banner clearly indicates the mode. This is where rooms and devices are created, renamed, reordered, or deleted.

Adding a device – in 3 steps

  1. Choose the device type (light, dimmer, blind, heating)
  2. Enter name, KNX group address(es), and room
  3. Test the connection and save

Frequently asked questions

Do I need an internet connection?

No. Smart Control connects exclusively and locally to your KNX IP gateway on your home network – no internet, no cloud.

Do I need to register or create an account?

No. There is no login and no account. You set up your gateway, rooms, and devices directly in the app.

Is my data stored online anywhere?

No. All configuration data (gateway, rooms, devices, settings) stays exclusively on your device.

Which KNX gateways are supported?

Any KNX IP gateway with KNXnet/IP tunneling, e.g. from Weinzierl, MDT, or Siemens.

Can I accidentally change something while controlling devices normally?

No. Controlling (operating mode) and setup (configuration mode) are strictly separated – editing options aren't even visible during normal operation.

What happens if the gateway is unreachable?

The app shows the connection status and offers a "Reconnect" option. Until reconnected, the last known states are shown read-only and controls are disabled.

What languages is the app available in?

Multiple languages, including German and English. The language can be set in the app's settings independently of the system language.
