Apologies if this has already been addressed. The closest forum post I could locate was from 9/2017 and it was more about how to configure.
The issue I have is that ‘off’ commands do not completely turn the bulb off. The first off command sets the brightness to about 30%. The second off command brings it to 0%.
When the bulb is turned back on, it has forgotten the brightness setting.
