Wall switch don’t work with Fibaro d2

Hi, I have just connect my first Fibaro dimmer 2 with my st. But I have some problem.
I can turn on and turn off my lamp in the app but I can’t use my wall switch any more. Nothing happens.
Second, on my dashboard it just says “turningon/turningoff. And the dimmer is always at 0% even if the lamp is in full light.

Any suggestions?


Thanks for fast reply, sorry if I’m sound like I newbie(I really am)
I have a wall switch that don’t fold back, (I have ordered new ones) as for the handler I don’t know, I just pair it through my iPhone app.
