Had the same issue. When using HomeKit scenes, they would throw an error. Homebridge log showed the invalid argument. The problem is that the Kasa api doesn’t like setting brightness to 0.

To turn off the lights without throwing the error simply tap the left side of the button in HomeKit to turn the light off.

Dimming to 0 will turn it off but throws the error.

Tapping the button on the left side on the actual little light bulb will turn off.

I fixed my scenes by using this method to turn the bulbs off when setting up the scene.

Hopefully this helps somebody.
