Dimmable lights not working properly

[ElWi]

When I set a dimmable light for example at 20 % using siri speech the light fluctuates 5 times from no light to bright light before it becomes stable at 20 %. I do not have this problem when I use the homekit app. We have the problem with speech control on all our dimmable lamps.

I'm facing the exact same problem.

Same here just with siri.
