Today my KS8000 stopped working with Smartthings, my suspicion is that recently an update was pushed to the TV (1203.6). I’ve tried to reset the TV, reboot TV/router/hub, remove and re-add TV as thing. However, once I removed it, the app discovery can no longer find the TV. By looking into the IDE/L…

Looks to be more of a HDMI port issue if it persist after a reset. I have not observed any of the issue you described after the firmware update.

Same here, didn’t know you can do soft reset by holding power button. I have done hard reset before, it worked a while (few days to weeks) but then the negotiation problem comes back again.

This is the first time I have had the issue. I only use HDMI 4 for the ARC and its connected to a Yamaha 783. Worked great until about a week ago. I didn’t even know the TV did a firmware update. I’m trying to find more info online when I get time, but it’s pretty hit and miss.

Same issue here. Last Samsung TV update broke integration with SmartThings

Same, integration is broken for me now! Can’t re-add the TV in smartthings either. Reported to SmartThings support and linked this and the other thread.

Everyone should open a ticket with ST and Samsung in regards to this issue. More tickets = faster resolution.

I’m seeing the same issue and opened up a ticket with SmartThings support. Here’s hoping it helps.

I am experiencing the exact same issue as everyone else here and will report it to support as well.
