Z-Wave Mertens 506219 switch

I happened to got this double wall switch Mertens 506219 that is Z-Wave and was wondering how to use it. It is my first Z-Wave device. Z-Wave JS Config DB Browser

I am trying to figure out the button presses, as it is double switch, it basically has four buttons. But looking at the sensors in Home Assistant, I do not seem to find a sensor that I could use in automations.

There seems to be only one sensor that triggers when I press any button event.battery_powered_wall_controller_event_value and that has attribute “value” that is either “0” or “255”. But the thing is that both “up” buttons trigger it the same way and both "down! buttons the same way so there is basically only two buttons based on that.

Any tips on how to work with this switch properly?
