Hi Mario,
There are separate topics for many Homey apps here in the forum. These topics provide detailed information on setting up and using the apps, as well as troubleshooting.
There is usually a link to the relevant topic in the Homey App Store:
In these topics, the app developers themselves are usually active, answering some questions and responding to functional problems.
Therefore, take a look at the first post in the relevant topic and follow the instructions. If you still encounter problems, feel free to ask questions.
