Hello,

how can i get a full description ( with “action” ) of my Item through REST API or KARAF ? For example my Item windfang_licht is shown as:

{
    "link": "http://xx.xx.xx.xx:8080/rest/items/windfang_licht",
    "state": "OFF",
    "type": "Switch",
    "name": "windfang_licht",
    "label": "Licht Windfang",
    "tags": [
      "Lighting"
    ],
    "groupNames": []
  }

My *.items file contains following:

Switch windfang_licht "Licht Windfang" ["Lighting"] {modbus="licht_eg:1"}

How can i get the {modbus=“licht_eg:1”} ?

Best Regards
Kay
