I have set up my Samsung TV UE40NU7120 with Sonos beam but cannot get the "turn off tv" control working.
Whenever I say "Alexa turn off the TV", the response is just "ok" then nothing happens....

The source input is usually a button on your remote ... so you would switch that to the HDMI-ARC port number, (Example HDMI-3 or whatever one you have plugged your Beam into) before then giving the instruction 'Alexa, turn off the TV' ... although the source is also accessible via settings ... I would try that.

If that fails and you do look at the Harmony Hub.. it will do the following;

Turn TV on/off
Adjust volume up/down/mute
Pause/Fast Forward/Rewind TV if your TV supports that.
Change TV channels .. upto 50 favourite channels can be chosen
Change input sources
Launch Apps built into the TV (Netflix etc.)
Control other devices attached to the TV (Apple TV, PlayStation and many others)
Adjust Hue lights in the TV viewing room.

All above can be done via Alexa by adding the Harmony Skill to the Alexa App... all the TV setup is done on mobile devices via a free downloadable Harmony App... see the two screenshots from my own setup.

The Hub also works with Google Home and with Sonos speakers direct using the Sonos API .

Hi to All, I believe I have found a workaround for Samsung TVs which solves the “turn off” command with Alexa on Samsung TVs.

First of all you need to install the Samsung app SmartThings and then add your TV as a Device. Then you need to add the SmartThings skill in the Alexa app and discover devices. For detailed steps on how to do that please check here:

After you do that you need to rename your TV in the Alexa app to something simple like Samsung TV for example. Then if you say “Alexa turn off Samsung TV” TV turns off. To turn TV on you must use the name your TV is recognized with the Sonos Beam so avoid naming both devices as TV since this will not work. All other functions like adjusting volume work fine as before.

In essence what this trick does is that it overrides the issue with the Samsung CEC for turning off the Tv. On the other hand the SmartThings skill has the issue that it cannot turn on the TV by voice command so this is solved by the Sonos Beam feature.

In my case I have used “TV” as the name for the TV with Sonos Beam and “Samsung TV” for the SmartThings TV. So to turn tv on I say “Alexa, turn TV on” and to turn off “Alexa, turn Samsung TV off”. It works perfectly fine and the good thing is the SmartThings will enable in the future other capabilities like changing channels or source.

Hope this helps.
