Ritto bell system compatible?

I wanted to ask if my bell systems can be compatible with the nuki opener …

It is a Ritto bell system. One Ritto employee emailed me the following:

<> purely visually from the outside without seeing the inside of the phone it is the “Ritto Mehrdraht Wohntelefon 653070”. You can use the “Wohntelefon 1663073” as replacement. <>

Is that opening system compatible?

How can I test it?


Hi Dan,
your intercom model “Ritto Wohntelefon 6530” has just been added to the list of compatible systems!
Best Regards
