[DEPRECATED] Kasa Plug, Switch, and Bulb integration

Forgive me because I couldn't possibly read everything, but I was thinking of picking up the Kasa for a few spots that were simply "less important" and didn't want to buy a more expensive zigbee/zwave motion switch or a smart switch+separate motion sensor.

But then I came across this:

and am simply... confused? That almost makes it sound like the integration does nothing/can't actually receive events. So what DOES the integration do?

I am looking to get either the motion sensor switch or dimmer. It will turn on the connected light (no need for smarts here obviously) but I may also want to trigger another device/event.
