To be able to use the configuration option via the app, the HomePilot must have at least version 5.0.39. Check whether an update is available for your HomePilot by accessing the user interface via your web browser http://homepilot.local or alternatively via the IP address of the HomePilot. Under Configuration System the current version is displayed.
If you have a HomePilot 1, the configuration via the APP is unfortunately not possible.
The app must also be up to date. Check the version in your smartphone and perform an update if necessary.
Check whether the configuration mode of the app is deactivated. To do this, click Settings in the app. If the configuration mode is deactivated, you can control all devices and scenes, but you cannot make any configurations.
