I hava a UN55MU7000 TV i’m not sure if is fully compatible but my problem is that smarthing find the tv automatically add it but once is off i can’t turn it on
Samsung TV integration is currently, as one could say, broken. This is due to a firmware update on the TV. You are lucky to see yours as a device. The only thing (other than harmony hub or other IR blaster) that I have found to turn one on is the Samsung Connect app, and that only works some of the time.
There are plenty of threads on here about the current issues.
Thank you for the response i hope they fix it soon
