Unfortunately certain lamps turn on by just changing the dim value, even if the value wasn’t equal to zero.
So you’ll have to make a change request at https://homey.app/support.
(Chances are low, it’s been like this for over 4 years of using Homey).
And changing the dim value to 0, turns the lamps off, instead of dimming to the minimum level.
Maybe you can workaround it by using the Zone Memory app.
Not sure if the recently added “Moods” functionality can help.
