Hi!

Did you check this post?

Help ! Samsung TV Bindings with >2016 Samsung TV

Everyone, I have updated the samsungtv binding to fix a number of bugs that I found with the current version (including not saving the token, power buttons not working, binding not initializing properly, power state not reported correctly, and some other non-obvious ones). I have also optimized it to work correctly with Frame TV’s. I did add one new feature.

Thanks Tom,

i installed this updated binding and it no longer causes the error, however it also does nothing when i change the sourceApp channel, theres no error but the app does not open, thanks anyway.
