Button Washer finished
Hey, I don't know if I am confused but the washer finished Button does not work (maybe with my washer/dryer). 

IT's a button. Who or what does press it?

I have tested this by setting up a light or a sound to be played if this button is pressed - nothing. 

Nothing will trigger this button I watched it in HK.

The only thing to trigger a finished washer is to set an automation that reacts to the remaining time. But my problem here is, that the time is not linear. It depends on the washer. If the time runs out and the washer desires to e.g. dry 2min more the time will refresh. So I will get a Lot of notification until the washer is really finished. 

Can you explain how the program finished button should work?
