I've made a Home Theatre with the FireStick TV 4k and the Echo Plus (2 times) systems. But everytime i ask Alexa to play Music (with TV off) it starts music, and turns the TV on. Thing that considering that all was made in the Bedroom, it is annoying. Sleep music is so not possible, as the TV turns on, and makes a lot of Light. Is there a solution you know of?
I don't think the Alexa-verse is smart enough yet.
If both the stick and speakers respond to "Alexa" that might be the cause of the problem. You could try changing the speaker response name to Echo or computer. The problem may be that they then won't work as speakers for the TV.
You could get a non Alexa soundbar or speakers for the TV and use the Plus speakers for music only.
But that's not the point. The amazone team says it should work as they know.
But even if i change the names of the Echos (i mean command response) than the musik doesn't work. It turns everytime the tv on. I know i could buy a soundbar, but that's not what i wanted.
