I have an older Samsung UN58MU6100 which used to work with SmartThings. Recently I’ve noticed I can no longer turn the device off using any automations or voice assistant commands. I removed the device and tried to re-add it and I cannot re-add the device. I’ve also factory reset the TV and still no options to reset it. Does SmartThings deprecate older items like this and just refuse to work with it?
In a word, yes.
I’m in the same boat with a 4 year old 40-inch TV in our kitchen. Can’t lay hands on the model number but it was showing in SmartThings as “Series 6 TV” but was offline. I assumed it was not going to work but deleted and tried to pair but failed.
It’s a 2017
