Fermax 3444

Hola, tengo un telefonillo Fermax 3444 y no consigo conectarlo al opener. Habría alguna posibilidad??. Añado foto a ver si alguien me sabe decir algo.
Muchas gracias

Hello Pablo,
No. It is a two wire digital bus. From the Duox Plus line from Fermax. Sorry… Only way to open the entrance is set the intercom to automatically open the building door when you apartment number is pushed… This is done without Nuki Opener or
you can try a Switchbot and the Switchbot hub… This works well… Problem is that you need two separate applications to get in the doors.
Best regards,
