Slow transition?

I want a slow transition, but my bulbs change quickly. How can I specify that, and what is the limit? I don’t see a way to edit the pattern without AI and it doesn’t seem to understand me. 

Thank you! 

Dear User,

Thank you for reaching out. 
For light bulbs, we recommend using the AI function to find the light effect you want, and then you can adjust the speed as desired. You can also try commands such as “fading blue” or “fading colors.”
Please feel free to contact us if you have any questions.

Best regards,
