Expert answers to your questions

How many devices can be integrated in a LUXORliving smart home system?

The system can be equipped with a maximum of 64 hard-wired LUXORliving devices and can be extended to include additional wireless components.

How are the individual functions operated on site?

iON push-button sensors or conventional push buttons are used for operation. They are integrated into the system via push button interfaces or binary inputs. Alternatively, Amazon Alexa or Google Assistant voice control can be used for easy operation.

What type of communication is used and how must the connection be established?

Communication is via a 2-wire bus, to which each device has to be connected. Alternatively, communication is via the frequency 868 MHz for the wireless components. KNX S mode is used as a protocol. The bus connection can be executed as a line, star or tree topology. The following cable lengths must be observed:

  • Power supply – participant: max. 350 m
  • Participant – participant: max. 700 m
  • Total cable length: max. 1,000 m

For the bus connection, a KNX-certified bus line (J-Y(St)Y 2 x 2 x 0.8 mm) has to be used. The range of the wireless components is dependent on the structural circumstances, but generally it is approx. 30 metres.

How are the individual components configured and programmed?

The free LUXORplug Windows software is used for configuration. For project planning, the system that has already been installed and the connected components can be loaded. Alternatively, you can plan the project completely manually. A connection to the system control centre is not necessary for project planning.

What types of switches can be used with LUXORliving?

You are free to choose any type of switches and push buttons. Any floating switches and push buttons can be integrated into the LUXORliving smart home system via the LUXORliving T2, T4 and T8 button push button interfaces. This also applies to other consumers with floating contact, such as smoke detectors. Non-floating contacts, of motion detectors for example, can also be integrated into LUXORliving via the LUXORliving B6 binary input module. Alternatively, you can use the iON tactile sensors and room controller.

What type of lamps can be controlled with the LUXORliving dimming actuator?

The LUXORliving D2 and D4 dimming actuators are designed for incandescent and halogen lamps, as well as dimmable LED lamps. Special attention was given to dimming LED lamps. These can be dimmed in a flicker-free and continuous manner with LUXORliving. Lights with a DALI interface can also be integrated via the DALI actuator D4 DALI.

Can the dimming output of the LUXORliving dimming actuators be increased?

In short, the LUXORliving D2 dimming actuator can dim 400 W per channel and the LUXORliving D4 200 W per channel (in RC mode, this also applies to LED load). Generally, these output limits are sufficient. If the load still needs to be increased, the LUXORliving D2 can be extended with the DMB 1 T dimming booster (max. 2 x DMB 1 T per channel).

How reliably do the LUXORliving switch actuators switch high inrush currents?

The LUXORliving S4, S8 and S16 switch actuators are optimised for capacitive switching loads and are equipped with corresponding relay contacts. Inrush currents of up to 800 A/200 µs are no problem.

How is the room temperature controlled in the LUXORliving KNX smart home system?

The room temperature is measured via the iON tactile sensors or the LUXORliving R718 room sensor. Alternatively, the room temperature can also be measured via a temperature sensor on the LUXORliving T4 or T8 push button interfaces. The set temperature is adjusted in the iON8 room controller, the LUXORliving R718 room sensor or in the LUXORplay app.

How many scenes can be saved and controlled?

32 individual scenes can be saved and retrieved.

How many users can access LUXORliving simultaneously via the LUXORplay app?

A maximum of 5 users can access the smart home system simultaneously. Please note that the loading times will be longer if several users are connected at the same time.

Is start-up possible even without an Internet router?

The computer can also connect directly to the system control centre using LUXORplug. All you need is a LAN connection between PC and system control centre. However, an Internet router is absolutely necessary for subsequent operation with the LUXORplay app.

What happens if the IP1 system control centre is disconnected?

Thanks to decentralised intelligence inside the LUXORliving system, all basic functions will be preserved via the operating controls on-site. However, additional functions, such as time and scene controls, as well as operation via the LUXORplay app, depend on the system control centre.

Can the LUXORliving KNX smart home system be extended?

Thanks to the simple, standardised system design, you can expand the system at any time with additional KNX components. The existing LUXORliving components are then programmed using ETS. However, this will mean that you can no longer use the LUXORplay app for operation.

Is generating the visualisation for the LUXORplay app very time consuming?

Absolutely not. The visualisation is generated automatically when you use LUXORplug for project planning. After programming, all you need to do is connect to the IP1 system control centre using the LUXORplay app, then you will be apply to view and operate all functions immediately.

If a device in the system has a defect, do I need to reset everything?

No. If a device has a defect, you only need to replace that device with one of the same type. In the LUXORplug software, open the System menu and search for the new device by activating the Load system menu. This can take 1–2 minutes. The newly detected device will then be displayed in green in the list on the right. The device that has been replaced will be displayed in the list in red. Now all you need to do is drag the green device symbol onto the red one. Then reprogram the system and remember that you also need to restart the Prepare LUXORplay menu.

How can I reset a programmed device to the factory setting?

Master RESET IP 1:

Attention – the password is reset to the admin setting. All saved data/projects will then be deleted. Using the arrow button, select the RESET menu option on the display, then confirm with the Return button. Then select the MASTER RESET function in the selection menu and press the Return button for approx. 10 seconds.

Restart IP 1:

If you select the RESTART DEVICE function, only LUXORliving IP1 will be restarted. No data will be lost, but all active connections to the system will be interrupted briefly.

Device RESET (for all hard-wired LUXORliving devices):

Attention – the device must then be reloaded and completely reassigned and programmed. To start with, press the left button of the P640 power supply briefly – the red LED will light up for 20 seconds. Now press the Prog button for the LUXORliving device that is to be reset until the red LED on the power supply has gone out. Then release the Prog button.

Device RESET (for all wireless LUXORliving devices):

Attention – the device must then be reloaded and completely reassigned and programmed. Switch off the supply voltage to the device. Now press and hold the Prog button for the LUXORliving device that is to be reset while the supply voltage is switched on again. After a further 2–3 seconds, release the Prog button.

Device RESET via LUXORplug:

Some LUXORliving devices can also be reset directly via the device view in LUXORplug.

Can several heating circuits/actuator channels be controlled with one room temperature controller?

In general, several actuators can be connected to each heating actuator in the LUXORliving series. However, if you need more in large rooms, you will need to group channels for this.


  • Create a heating function in the room structure.
  • Connect an actuator channel (right list) to the heat function.
  • Open the group function.
  • Create a new heating group, e.g. living room group.
  • Now connect the required room temperature controller for the group to the newly created “living room group” (not as usual with regard to trigger).
  • Create one or more additional heating channels.
  • Now open the group window and activate the channel for participating in the “living room group”.

Is it possible to group functions, e.g. switching/dimming/blinds?

If, for example, the light and a fan in a toilet need to be controlled in parallel with just one push button, then you can use this function.

  • Create a switch function in the room structure.
  • Connect a switching channel to the switch function.
  • Create a new switch group, e.g. “toilet group”.
  • Now assign the button in the toilet to the “toilet group”.
  • Create a second switch function, e.g. fan (setting the switch-off delay).
  • Now open the group window and activate the channel for participating in the “toilet group”.

Is wireless communication protected?

Yes, communication for the wireless components is encrypted, meaning it cannot be manipulated or read.

How many media couplers can be used in LUXORliving?

We recommend using a media coupler. To optimise the range, the repeater function of individual wireless components can be activated instead of using additional media couplers. Please note the information on using repeaters in the system handbook.

Does each media coupler count as a device on the TP bus?

In terms of the power supply, each media coupler runs via the bus voltage and is classified as 1 device.

What is the range of the wireless components?

The range of the wireless components is dependent on the structural circumstances, but generally it is approx. 30 metres.

Can wireless communication be optimised?

Yes, each wireless component can be used as a repeater and repeat the wireless signal. The signal quality is displayed in LUXORplug so that individual products can be used as repeaters in a targeted way.
