Workaround for the previous post limitation.

By using a custom list widget, slight modification of @rlkoshak example custom list widget for presence, setting the actionAnalyzerItems field is not required any more.

uid: listWidget-presence
tags:
  - list
  - presence
props:
  parameters:
    - description: The label for the widget
      label: Person
      name: title
      required: false
      type: TEXT
    - context: item
      description: The presence switch Item
      label: Item
      name: item
      required: false
      type: TEXT
  parameterGroups: []
timestamp: Aug 17, 2021, 10:37:02 PM
component: oh-list-item
config:
  icon: f7:person_circle
  iconColor: '=(items[props.item].state == "ON") ? "green" : "red"'
  color: '=(items[props.item].state == "ON") ? "yellow" : "gray"'
  title: =props.title
  item: =props.item
  badgeColor: '=(items[props.item].state === "ON") ? "green" : "red"'
  badge: '=(items[props.item].state === "ON") ? "IN CASA" : "FUORI"'
  action: analyzer
  actionAnalyzerItems: =[props.item]

The last line is tricky. I was naively trying

  actionAnalyzerItems: 
  -  =props.item

but it didn’t work. I found in another rlkosk example that the right syntax was the one that i showed in the working yaml.

Once this widget is saved under the developer tools , a simple items definition such as

Switch Pres_Silvana    "Pres Silvana [%s]"   <presence>  (gEquip_PresPD) ["Status","Presence"] {channel="xxx",
         listWidget="widget:listWidget-presence"[title="Silvana" ]
         }

allows me to define the widget in the items file
