I’m also bumping this topic. I have a pile of Blue switches ready to go into a new build, and there’s a part of me that’s worried I will one day be pulling out everything that needs to dim and getting Lutron Caseta instead. Every LED bulb and fixture I’ve used with a blue switch in dimming mode on my bench test unit has unacceptable flickering and buzzing. These switches contain the hardware to properly dim an LED light, but have been designed to sacrifice ideal dimming in order to maintain non-neutral installation capability instead. I hope there can be a future firmware update to make these actually workable as dimmers in the modern lighting world. The on/off function works well, but the other issues raised in this thread have me worried about longevity of the switches and fixtures even in that mode. I love all the smart features, and the look, but this is a huge achilles heel. My old Inovelli Red dimmers were never functional as dimmers for all the same problems, so I’ve been using them as generic smart switches instead. I was hoping the Blue would have solved that limitation.
