"ms.channel.unauthorized" when connecting to Samsung TV UE55NU6035


Is it impossible to communicate with this Tizen-enabled TV?

I get this when pressing the on/off button in the UI:

I got this as well when pressing the on/off.

Samsung Tv Nu8000 (2018)

  - platform: samsungtv
    host: xxx.xxx.xxx.xxx
    port: 8001
    name: Samsung TV
    timeout: 30
    mac: 64:1c:ae:11:14:d5

Same problem here. I have a NU8000 and this is my configuration.yaml :

  - platform: samsungtv
    name: Samsung TV
    mac: 64:1b:ae:2w3:2b:3q
    port: 8001

I can switch on the TV (I supposed because of “wake on lan” and mac address), but can’t switch it off. I get the message:
Failed to call service media_player/turn_off. {'event': 'ms.channel.unauthorized'}

Have you figured out?


Same problem here. I guess we need to allow the Raspberry Pi on the TV to permit it to send commands. I got a message on the TV asking if I want to allow my mobile phone, but not the HA so not sure how to do it.

The HA does not appear on the TV list for Denied devices nor allowed.
