I have a smartthings hub and 2 Samsung TVs. The smartthings app on iPhone can fully operate the TVs but alexa cannot control volume or inputs and anything I ask it responds with “TV does not support that”. If I ask Alexa to turn off the TV, it does it successfully.
Note: This is not about not being able to turn on the TV, Alexa responds with “TV is not responding” when the TV is off which is a known and well documented issue.
I do not know if my TVs are supported but I assume they are since I am able to fully control them from the smartthings app. I can use all displayed functions in the app like change input, volume, mute, home, select, arrows, etc.
TV Models: UN65MU8500 and UN65KU6300
Hub Model: SmartThings V3 (IM6001-V3P)
Network: All devices and TVs are connected with Ethernet cables but I have tried to change them to wireless also which made no difference.
At this point, I just need an answer as to can I control my TVs with Alexa or not. If I cannot because of the equipment versions, I will just stop wasting time trying to make them work with Alexa.
