Also, if you like the television you have except for the issues of powering it on, another option might be just to get an inexpensive IR blaster that works with smartthings.
I have exactly this issue with one of my televisions, although it’s not a Samsung brand, and I use a SwitchBot mini hub just to turn it on.
Here’s an old commmunity article I wrote about that option. You don’t need to have a smartthings/Aeotec hub to make it work, switchbot provides its own cloud to cloud integration with smartthings.
