Many lights already turn on by just setting the dim level, so disable the ‘turn light on’ card to check if it works.
If that doesn’t work,
you should always turn it off like this:
Then…
-dim light X to 1%
-turn light X off after 1s
When turned on, it should always be dimmed to 1% instead of 100%
Seems a bit clumsy, but it works. Maybe you can drop Support a note if a default dimlevel can be set permanently thru device settings.
