i want with my Openhab and the Harmony Bind mute my TV. I have am Soundbar an the Name is
"Samsung-Verstarker" yes no Upperpoints :slight_smile:

This is my Item:

String HarmonyHubMute        "mute"    { harmonyhub=">[press:Samsung-Verstarker:MUTE]" }

But when I chance the Status with the funktion in OpenHab Rest–> ITMES nothing work
