I'm trying to use a Widget on CarPlay so that I can turn on my porch lights, connected to a Kasa Outdoor Smart Plug, from my car.  I don't understand how the widget works.

I created a widget from the CarPlay settings adding 2 devices.  Both are SmartPlugs.  I just want to be able to turn the sockets on & off from my car.  (I created a similar widget on my iPhone just to see it that worked any beeter, but it is equally confusing)

Here's what I see:

My questions:

1. How does this work?

• What does the circular arrow do?  When I click on it, it changes to a checkmark, but doesn't seem to do anything.
• If I click on the power icon in the lower right, it does seem to turn on the plug (and the lights attached), but not sure it's consistent.

1. Why do I only see one of my devices?  How to I access the 2nd device?  I can't figure out how to control the other plug.
