3. Click create project. Your new project will open to the ‘Buildings’ tab.
4. Click the ‘+’ (new tab) button to open the ETS6 dashboard.
5. Hover over your newly created project under ‘Local Projects’ and click the ‘Details’ button to open the project information menu.
6. Find the details panel and click on the ‘Details’ button to open the details menu.
7. This menu will allow you to modify project details. This information will be saved with the projects. Description can be used for things such as usernames and passwords or notes about the install.
8. Close and return to the dashboard or your project tab.
9. ETS projects are saved automatically to the local database.
10. To move the file between computers or to save elsewhere you need to export the file. Return to the dashboard, hover over the project and click export. This will bring up a dialog to save somewhere on your computer. See tutorial 15 for more in depth look at importing and exporting projects.
1. ETS has a number of panels which show different things. For this guide, we will focus on 3 panels. The devices, group addresses, and diagnostics panels. Drop down the panel’s menu found in the upper right corner and star the 3 panels shown.
2. The panel can be changed and manipulated also in the upper left hand corner of the panel as shown here. Notice how it can be changed, moved, closed or opened in a new window.
3. ETS6 uses a tab-like layout. New tabs can be opened which take you to the dashboard. The dropdown box allows you to open new panels in the currently opened project. Multiple projects can be opened at the same time.
4. ETS6 has a number of panels available, they are:
- Buildings: Create building structures and organise devices.
- Group Addresses: Add and link group addresses.
- Topology: Define the bus structure and individual addresses.
- Project Root: Summary of all project views in one compact tree view.
- Devices: Device management, parameters and group objects linking.
- Catalog: Used for adding devices to your project.
- Reports: Generate project documentation.
- Diagnostics: Tools for monitoring and debugging the KNX install.
At Knxtra we use the Devices, Group Addresses and Diagnostics panels the most often. Consider starring them to add them to favourites.
1. Change the panel to the ‘Devices’ panel.
2. Click ‘Add Devices’
3. This will open the ‘Catalog’ panel.
4. Use the search bar to find the device you want to add. In this tutorial we will be adding the 4-input switch interface from MDT.You can search for product code.
5. Select the correct device. Check the device version and codes match.
6. Set the amount you want to add and click ‘add’.
7. The device will appear under the ‘devices’ section.
8. The individual address can be set under the properties->settings tab on the righthand side. The name and description can be modified under the properties->settings tab. Comments can also be added. It is useful to describe the location of the device and any key programming things for future reference. Changes and todo’s are also very useful.
9. Repeat this for the 8 channel relay.
10. Set the Relay’s individual address to 1.1.100. At KNXTRA, we like to group correcponding devices together. In our programming you will often find sensors starting at Individual Address x.x.1 through to x.x.99. And you will find actuators starting at Individual Address x.x.100 onwards.
11. The device will appear with the correct individual address in the devices tree.
Repeat this process to add all devices. If a device is not available in the catalog, see the other tutorial.
1. Find the .knxprod file you want to import from the manufacturer’s website and download it. For this tutorial we will import a discontinued Eyezen TP .knxprod file from https://www.zennio.com/product/eyezen-tp. Download the ETS application program, extract the .zip file and save to your hard drive.
2. Change the panel to the ‘Devices’ panel.
3. Click ‘Add Devices’
4. Click ‘Import’ and navigate to the .knxprod file.
5. Select English and click ‘Import Selected Languages’.
6. This will add that device to your ETS6 catalog and be available for use in any future ETS projects.

Linking group addresses to group objects enables the communication between devices. There are a number of ways to link group addresses.
1: Dialogue -> Group Object
Once you have adjusted the parameters of the device and created the relevant group addresses to meet your specifications, open the group objects tab. To link the group objects to group addresses via this method, right click on the group object and select ‘link with’ or press ctrl+shft+a. Navigate to or type in the group address and click the ‘link’ button. You are now linked! The group address number and name should appear under the ‘linked with’ and ‘group address’ columns next to the selected group object.
2: Panel -> Group Object
To link the group objects to group addresses via this method, open both the group addresses and devices panels. Navigate to the group objects tab in the devices panel. This can be done across two separate windows or within one. Hover over the relevant group address then left click and drag until you are hovering over the group object that you wish to link. Release left click to link. You are now linked! The group address number and name should appear under the ‘linked with’ and ‘group address’ columns next to the selected group object.
Note: You can do this process from group addresses to group objects and group objects to group addresses. You can use whichever direction makes most sense to you.
3: Groups Tab -> Group Object
To link the group objects to group addresses via this method, open the devices panel and navigate to the group objects tab. Open the groups tab located under properties on the right hand side. Find the group address you want to link and then drag and drop onto the relevant group object. You are now linked! The group address number and name should appear under the ‘linked with’ and ‘group address’ columns next to the selected group object.
Each method works and it’s up to personal preference or situation for when to use each one. Experiment and see which one makes the most sense for your workflow and process.

You may consider unloading a device to reset it to reuse on a new job or to ‘hard reset’ the software in a device. The device will not function when unloaded but is able to accept a new download from ETS where it will continue to function.
1. Open the ‘Devices’ panel.
2. Right click on the device you want to unload.
3. Select Unload & Address.
4. Press the programming button on the relevant device and wait for the unload to finish. Once it has finished, the programming light will turn off.
5. Repeat for all devices.

KNX Programming Guide
A Day/Night function is often underrated it can be used for many thing. Its helpful for light and heating control allowing you to dim touchscreens at night and even reduce temperature while the building is unoccupied etc
Beyond the basic mode switching, the Day/Night Object could be used to block specific functions or controls. For instance, you can make a control visible only during the day or disable a sensor light during the night. This adds a layer of customization and control to your KNX system.
Controlling the Day/Night Object.
The goal is to have a device output a 1 during day time and output a 0 during night time. Here are a few methods to achieve this:
- Dedicated Day/Night Outputs:
Some devices come with dedicated day/night outputs. These devices either have an onboard clock or be connected to the internet through a time server, that automatically transition between day and night settings.
- Lux Sensors:
Another option involves using sensors that can detect lux levels. Set a threshold, e.g., 100 lux, and instruct the device to output ‘1’ when lux is above this threshold and ‘0’ when it’s below. This method ties the day/night mode to ambient light conditions.
- Timers:
Utilize timers on devices like Zennio touchscreens. This allows you to schedule the day/night mode switch at specific times. For example, you can activate day mode at 7 am and switch to night mode at 7 pm. These timers are often customizable to meet individual preferences.
The Day/Night group address can then be assigned to the day/night group object of devices that have the inbuilt functionality. If a particular device does not have Day/Night functionality then logic ‘And’ and ‘Or’ gates can be used to manipulate telegrams.
Day/Night modes are typically controlled by 1-bit group objects, where ‘1’ represents day mode and ‘0’ represents night mode. By default, devices are set to the day mode, and if the day/night object is connected, they will switch accordingly.
This picture shows how there are settings that are related to the day mode and night mode.
Conclusion
Effectively implementing day/night modes in your KNX system enhances both energy efficiency and user experience.

Miscellaneous Guides
Purpose:
Ripple Control can affect electrical devices within homes. This document outlines how Ripple Control can affect lighting dimmers within NZ homes and remedies to this issue.
What is Ripple Control?
Your electricity provider will send audio-frequency signals along the ordinary electricity network to switch on and off appliances. This method of control is called Ripple Control.
Commonly, Ripple Control allows the electricity company to switch off appliances such as hot water cylinders during peak demand times and on again during low demand times. This allows for power savings across a city-wide electrical grid.
The audio-frequency signal is applied over top of the 50Hz AC sinewave (Figure 1). This causes a distortion and lowering of power quality.
Effects on Lighting and Dimmers:
A side effect of ripple control is that the signal sent through the ordinary network is received by all devices connected to that same network. Unfortunately, this means that many electrical devices including toasters, fridges, fans, fluorescent, halogen, and LED lighting will also receive the signal and may be negatively affected by it. This may cause buzzing sounds or other side effects from affected devices. In the case of LED lights, there can be a perceptible flicker, especially if connected to a dimming device or driver.
This issue is becoming more prevalent with the increasing use of LED lighting and advanced electronic dimmer controllers. In some instances, waveform distortion caused by Ripple Control signals, will lead to some LED lighting systems producing anything from a subtle flicker through to strobing.
The closer the home is to the ripple source (substation), the larger the amplitude of the ripple control signal which means larger distortion of the 50Hz AC sinewave and potentially larger effects.
Dimmers rely on zero cross detection (the point that the AC sine wave crosses the 0-volt point), and are very susceptible to ripple frequency as it causes the detection to fail. When this fails it causes the components that handle dimming, to switch at the wrong time causing damage to the device components and potentially the load connected as well.
KNX dimmers use the same dimming technology as the conventional dimmers discussed above.
Notes:
– Not all LED lights are affected by ripple voltage injection, some combinations of LED chips and LED drivers appear to be immune to the ripple injection signal while others are highly susceptible.
– The closer you live to a substation the more your home will be affected. The further you are away the more the frequency gets naturally filtered causing this effect to be minimal if at all.
– New subdivisions are often affected as the lack of homes in the area reduce the natural filter effect that occurs similar to that of being further away, As more homes are built in your area this effect will lessen. This number of homes can vary based on size of supply lines, substations and or transformers.
Solutions for if you are Affected:
3 recommended remedies to solve flickering lights:
– Swap out the electronics dimmers for normal switches or relays.
– Wait until your subdivision has grown.
– Install a filter for your home (currently not available for some regions).
If the flickering lights are causing a problem, please discuss with your electrician. Please be aware that there may be other causes including but not limited to the below:
– Power Quality
– Grid Drain
– Other devices in your home causing interference.
