Thanks for the reply. The version you have is a brand new (March 20 initial firmware release) hardware build and can not use the Built-In integration. The API, port, and encoding are based on the Tapo (i call it TP-Link protocol).
Work-around: Use the TP-Link integrtion at link: [RELEASE] TP-LINK TAPO Plug, Switch, Bulb, Hub and Robovac Integration
AFTER YOU OPEN THE APP, SELECT the OPTION "Install Kasa Hub and Matter Devices".
