Opener Keypad

I have a question: I have a Nuki Opener & a Keypad. How can I now control the whole thing so that when I enter the code, both the Opener and the Smartlock are opened?

It seems that you can only pair one device natively. IFTTT I also find no solution, because the keypad is not displayed as a user and the keypad generally also does not act as a trigger.

Otherwise, you could probably have said:

If Opener is opened by Keypad, open the Smartlock.

Does anyone have an idea?

This is correct. You can only connect the Keypad to one device.

You can currently only use specific entry codes as filter (via authorization name).
