Nuki opener combi with Ekey multi Relais

Hello,
I have an Nuki Smartlock, bridge and Opener and I’m wondering, If it is possible to connect one of the Relais from the “EKEY multi reg 4” with the opener to open and close the Smartlock.
My idea is to connect the blue and purple cable from the opener the relais3 (e.g.)
Is this possible and what cable do i have to connect to PIN 16/17 or 18?
Purple to 16 and blue to 17 or 18?

thanks for helping.

The Opener can not send lock commands to a Smart Lock, but you can modify a Nuki Fob and (basically) press the button with the relay of the Ekey.

A similar problem has been discussed here:

Verstehe ich das richtig, das der opener dann öffnet und der Fob z.b. dann schließt?

Oder geht es mit der Autolockfunktion durch den Türsensor-Magnet, welcher immer die Tür abschliesst und ich mit dem opener dann den Öffnungsimplus vom Relais sende?

Bzw. dachte ich das ich mit dem Opener auch Garagetore öffnen und schließen kann, geht das mit dem Nuki nicht auch?

The Nuki opener is - like the Smart Lock - an actuator that can be connected to an intercom or other locking mechanism (e.g. Garage door) in order to unlock it.

The Fob is an accessory that can send lock/unlock commands to Nuki actuators.

If you want to send lock commands to a Nuki actuator you need a Fob.
The Fob can be configured to lock, unlock/unlatch or „intelligently“ (= when locked then unlock. When unlocked then lock) a door equipped with a Nuki Smart Lock.
