Automation very slow hue changing scene

Configuration
1

Hi

I want to toilet licht to pick a scene based on the time of day. By day normal, By night dimed.
I made the following automation. While it does work it is realy slow, it takes 10-20sec. Can some1 point me in the correct direction.
-Maby its hue not being fast enough?
-Maby a hole different method?
-Now its reacting on classic physical switch, a hue switch would probably solve it but i dont feel like trowing extra money against it. They already have enouf of my money. Also this is also about learning and fixing the puzzle …

Thanks

You could try explicitly setting the transition time for the ‘scene.turn_on’ but I would have expected the transition time to be zero if not explicitly set.

What do you mean by a ‘classic physical switch’?

If you mean a dumb switch that kills power to the light when switched off, then the light needs to reconnect to your zigbee network when switched on and then react to the automation. You could get something like a Sonoff ZBMINIR2 that has a detached mode?
