Rademacher Homepilot (DuoFern) via http-Binding

Anyone got it already working on OpenHAB3 ?

Sending requests is working, but the update not…

My configuration:

UID: http:url:8208d83d49
label: RademacherRolladen
thingTypeUID: http:url
configuration:
  authMode: BASIC
  ignoreSSLErrors: false
  baseURL: http://192.168.0.23/v4/devices
  delay: 1000
  stateMethod: GET
  refresh: 30
  commandMethod: GET
  contentType: application/json
  timeout: 3000
  bufferSize: 4096
location: Buero
channels:
  - id: Rademacher_RolladenBuero
    channelTypeUID: http:rollershutter
    label: RolladenBuero
    description: ""
    configuration:
      mode: READONLY
      stateTransformation: JSONPATH:$.devices[?(@.did==1)].statusesMap.Position

In the log I get:

2021-09-24 15:40:35.003 [WARN ] [ofiles.JSonPathTransformationProfile] - Could not transform state 'UNDEF' with function '$.devices[?(@.did==1)].statusesMap.Position' and format '%d'

Why do I get “undef” ?

Json looks good.

{
   "response":"get_visible_devices",
   "devices":[
      {
         "description":"Rolladen Fenster",
         "deviceGroup":2,
         "did":1,
         "hasErrors":0,
         "iconSetInverted":0,
         "iconSet":{
            "k":"iconset8"
         },
         "messages":[
            
         ],
         "name":"Büro",
         "properties":{
...
         },
         "statusValid":true,
         "statusesMap":{
            "Manuellbetrieb":0,
            "Position":100
         },
...

Sending put is for working:

Sending put {"name":"GOTO_POS_CMD","value":"100"} to http://192.168.0.23/devices/1

I have this problem since update from OpenHAB 2 to 3.

Anyone got it working on OH3?
