Can a Z-wave keypad trigger a virtual switch in ST?

Is it possible to have a Z-wave keypad trigger a virtual switch in ST things, that I can then tie to turn on other non-zwave switches like Hue or something else?

I’ve seen the Aeon Minimote, but i wanted a wall keypad. Is there a Aeon minimote equivalent to that as a keypad?

No. Those switches are secondary controllers that need to send a command (on or off) directly to the device. As a Virtual Device only exists in the cloud, there’s no way to send that command to the virtual devices.
