Fade-in/out remove

Hello,

I have GU10 spotlights coupled to a switch with Hue Wall Switch. When these bulbs are switched on, I get a fade of about 1 to 2 seconds, and the same when they are switched off.

This is native to Philipps, is there any way to eliminate this mini fade?

Thanks

I’ve managed to switch on 1000 groups using the buttonevent automation without fading.

However, when I create another automation using buttonevent 0 (for off) it doesn’t work. What can I do?

Thanks
