Favourite colour group with automation

I face a new challenge:

How do I use an automation to control two of my light groups?

I can set a favourite colour for all of my 20 lights separately and then add each single light to automation in the Mi home app. But that is very complicated.

How can I set a favourite colour for a group in the Yeelight app and then choose that favourite with an smart switch?


No reaction…. Does this mean it is not possible?

In Mijia APP, devices support grouping. After grouping, devices are displayed in the form of groups. Automatic configuration can be made directly according to device groups.

But when you create a group, you can not choose a favourite color anymore. Only 4 default options.

Why is the menu of a single light different to a group? I really think the light options need some updates.
