I bought a few of the Sengled Smart Light Switches and have found that there is a slight delay (~1 second) when pushing button 1 (on) or button 4 (off). Button 2 (dimmer up) and button 3 (dimmer down) function much quicker.
I have heard that some controllers will delay because they're waiting for a double click. Is there some way to check and disable that for button 1 & 4? In my testing I see that button 2 & 3 do not register a double click when I look at them in the devices page.
