I've mostly used Alexa for lights and music.
The dimming has proved a little weird, and I'm not going with oddball colors. I've done some reminder things, and used the Dots mostly for music. And Amazon's selections seem sort of sparse in some areas. Generally decent with answers to stupid questions.
Next to set up some routines.
I haven't been able to link my A/C to it, but have been using its own app.
Probably going with a motion detector camera or two eventually.
