Adding a KNX ETS app can appear confusing first time around. Follow the steps below, or, get more help in the links at the bottom of the page.
The process is mostly the same for ETS5 and ETS6, though there may be some differences if you are using an ETS cloud license rather than an ETS dongle
Where to do the steps to buy and load ETS apps:
KNX Association Website
Your Computer
ETS 5 or 6 programme
Log in to your account on my.knx.org.
Go to the apps pages and find the app you are looking for.
Select 'Buy', go to cart and purchase (many apps are €0.00 so no payment needed). Don't forget to accept the License Agreements
Go to the Product menu and select the app product you have bought.
Go to ETS and make a note, or copy, your KNX dongle license number ie. KNX-A1234567 which you will find on the license page. Some apps are bound to your ETS license. Click on 'Product License' and enter your dongle license number which will create the license file
Download license and app files to your computer
Find the downloaded files in your file finder Install the app file into ETS using the 'ETS Apps' page, and then, 'Add license' file (if required) in the Licensing page which will activate the app.
Open your ETS project and Run the app by selecting the 'app' menu from the top bar menu, or If App is an 'in product' app then there will be a new tab in the device page.
