[SOLVED] Setting up a harmony button press item

Setup, Configuration and Use Beginners
1

Hello,
I want to setup an item to power on my device

The rest api shows

http://myip:8080/rest/channel-types/harmonyhub%3Adevice%3Awohnzimmer%3AHTPC%3AbuttonPress

"stateDescription": {
    "readOnly": false,
    "options": [
      {
        "value": "PowerOff",
        "label": "Power Off"
      },

how do I map this to a switch???

Switch item=HarmonyGreatRoomActivity mappings=[PowerOff="Power Off", TIVO="TIVO", Music="Music","APPLE TV"="APPLE TV", NETFLIX="NETFLIX"]

First of all you need the following entry in your .items file

String HarmonyHTPCButtonPress   "HTPC Button Press"  { channel="harmonyhub:device:wohnzimmer:HTPC:buttonPress" }

.

Then an entry in your .sitemap file:

Switch item=HarmonyHTPCButtonPress mappings=[PowerOff="Power Off"]
