Only two Alexa devices; an Echo and a Dot. Dot is by the bed. Since the bedroom light is in the bedroom, I really don't need to control it from another room. But I can use the TP-Link Kasa app on my iThingies to control it from anywhere in the world. I have another TP-Link bulb on my front porch, but it is warm white only, so I can only control brightness and on/off. Oops I almost forgot I have a FireTV with Alexa control too, but I have never used it to control the bulbs.
