Checked HS220 V3.26 datasheet, and I'm surprised to find out that the configuration method varies depending on the color of the casing. But not sure if that's relevant to your case?

  @GabrielMitch that is indeed interesting. I have the white one so I connected via wifi. It is interesting that the interface for the 3.26 switch is different in the kasa app. We get 5 brightness preset instead of 4 brightness preset. There is more device settings as well. That's why I figured the protocol might be different.
