Thx for the fast answer.
I tried to connect a lot of times as Popp device or general z-wave. I reinstalled the popp app.
Homey recognized the 1. and 2. push on z-wave button of the smoke detector and then comes the error message, that connection is not possible.
I have no other z-wave product and tried to connect direct near the Homey Pro.
It is the POPE701486 smoke sensor with controllable siren V 1.2
