I was attempting to "Piggybacking " off of C-Hans post dated 4-9-2020, the request was as stated above, the offered answer was "If you configure smart actions in the Kasa app you can look to have the other HS220 turn off or on, but not sync dim settings." As stated by Tony.

A year later an attempted bump of the conversation was made, no reply.

So 4 years later I'm bumping it again in hopes dimmer control can now happen? Also Ive been told a black HS / KS 220/225 is coming, if ganged dimming and on/off can happen, I will need four said switches!

Sooner than later as my project is nearing completion.
