I've got something weird going on with my new Zen30 800 series. With the default minimum brightness of 1% I can only only dim the light down to 43%, but that 43% is just barely on. It's a perfect nightlight level and what I wish I could set the minimum too. But, I set it to 40%.
But now with the minimum brightness configured to be 40% it barely dims at all. If I set the level to 3% (which should actually be 40%) it barely dims. I can set the level to 1% and it's barely dimmer than 1%.
I am not sure if it's needed, since it seems to sync after saving preferences, but I did press configure after each change. The log seems to indicate everything is normal.
EDIT: And I just swapped the bulbs with 3 identical bulbs currently on a Zen77 that I know can dim very low and are working fine and experienced the same behavior.
EDIT2: I don't know if this is possible... but could it somehow be the wiring between the plug and fixture, or the fixture itself? This Zen30 just replaced another Zen30 that was having really bad flickering when dimming.
