I’m going to resurrect this thread because I’m having this same issue and it doesn’t consistently works.
So you hold down to dim. Get to the lowest setting, release and try to press down again and it doesn’t turn off. Now i’m just rapidly hitting down or calmingly hitting down and it doesn’t turn off. Now sometimes it randomly works. Don’t know what part of the down button i’m hitting or what.
In the ST App, I can hit off and it turns off properly.
I tried a brand new button and same behavior. Even got new 4 Br30 9.5W bulbs to try and same thing.
