I have not been able to add my Fibaro motion sensor to my Homey Pro. I have tried re-adding the app, excluding the Fibaro, and re-adding it, but nothing works. I pulled out my former Homey and it added the Fibaro without an issue. I then noticed that my Homey is set for the hardware region of the US, and my Homey Pro is set for Europe. I cannot change it in either the Homey iPad app, or the web version. In the web version, the z-wave setting isn’t even available under the settings.
Set the Location in the Homey Mobile App , restart and Check,
Maybe even set it to far outside your Regio (fe to Europe), and move it back to your actual location (Regio US)
