Problem with Everspring Door-Bell

[vga]

Hi everyone
i bought a Door-Bell Set from Everspring, Push-Button: TAC06-0, Door-Bell TSE03-0
In Expert UI under "devices" is see the PushButton as a "Remote Controller" and the Door-Bell device as a "Audio-Controller"
When change state from door-bell in "Expert UI under Control" or "HA UI under Widgets", the bell rings.
But in "Expert UI under Control" or in "HA UI under Widgets" i don´t see the Push-Button.
Now in "Expert UI under Device" i associated the push-button to the door-Bell.
But now, when i push the button, the door-Bell don´t ring.

Does anyone have some experience with this door-bell and razberry?
Would be very nice if someone can help me, what i´m doing wrong.
I excluded and included the push-button many times, but never with success for ringing the bell.
Is there something special to look out for in associating the push-button to door-bell?

Thanks for help!

is there a general problem with "Portable Remote Controller" Devices in z-way server?
i have added another Switch "ZME_054436" to z-way server.
In Expert UI -> Devices -> Status i see the switch called the same as my Doorbell Push Button:
"Portable Remote Controller_X"
But i don't see these devices in the "Control -> Switch" section. Is this normal for switches?

It is not a switch, it has no relays. It is a rocker (remote control).You have it in config section: you can associatiate it with other devices
