I have several Kasa switches (3-way, hs200, and hs220) and installed lights where you can control the colour/warm by flicking the switch off and on rapidly -- 6 times to reset all lights.  I can't seem to do that on the Kasa app.  I'd double tap it to turn off and on but even that doesn't seem to register off and on once. I have the switch configured to instant off and on.  
 

Has anyone else figured how to use Kasa switches with switch controlled colours?
