I just added my first smart home device, a
TP-Link Multicolor Smart Wi-Fi A19 LED Bulb. Pretty cool. It didn't take long to set it up with my Wi-Fi account or with Alexa. Kind of pricey, to say the least, but at least it doesn't require a separate hub like the Phillips bulbs do. Still playing with it, but it seems to work fine and has some cool features. My main complaint is the Kasa phone app that controls it. There is an iPhone app, but no iPad app. Stupid! There is an Android app, but Amazon will not allow me to install it on my Fire HD 6, even though it is an Alexa certified device. Even more stupid!! I do have Google Play installed, but it no longer seems to work. I just get a blank white screen when I open it on my Fire HD 6. It was working, so I guess an update to the Fire torched it. So I can only review the Kasa iPhone app.
The iPhone app is pretty good except for one thing. There is a color picker screen that is rectangular and allows you to drag a bulls-eye with cross-hairs to whatever color you want to select. The problem is that the color selection rectangle goes from the left to right margins, and as such the bulls-eye cannot reach the far left side or far right side of the color scale, so not all colors can be chosen. Also the same is true for the top of the rectangle. No huge issue, but it is kind of frustrating. They need to learn how to better program the app.
It is easy to turn the light on and off with Alexa. I haven't discovered a way to change colors though using Alexa. I have to use the iPhone app for that. I'll keep experimenting to see if there is a command Alexa can understand to change color verbally. No, I doubt it will allow me to say "red" or "green" or such, but Kasa allowed me to set up light scenes wherein a color is assigned to each, so perhaps I'll find a way to enable the scenes via Alexa.
