Can HA09 trigger an event without assigning a scene to the button?

I’m still struggling with HA09 trying to control Schlage lock.

HA09 forks fine with the dimmers and light switches, you just assign switch to the button then add controller second time to Vera and bingo! Unfortunately, this way doesn’t work with Schlage.

Normally you should first assign device to scene button, add controller to the primary Vera unit again and only after that use event triggered by the button.

Is it possible to trigger the event without assigning the scene first?
