@vadimchp I am seeing similar to you. I changed my ZEN77 to be 5 seconds ramp rate both ways.
The main difference I have is the hourglass icon. I think because you are using custom icons that is not showing for you. Also I noticed on yours when you turn it off the slider eventually goes down to 0, mine is not doing that probably due to the driver. I am guessing the driver you are using is setting the level to 0 when it turns off which IMO is a bad practice. I like to keep the level showing where it was and only changing the state to off.
