Unfortunately, this switch uses the TP-Link Tapo application instead of the Kasa Smart app. The apps are essentially the same user interface, but these newer products that support matter required a separate app, as they have some slightly different capabilities that would not be compatible in the same app ecosystem as the previous generation. However, if you use Alexa or Google Home, you would still be able to consolidate all your smart devices into the respective smart home app. With Matter support, you could also use Apple Home now, whereas you could not before.
