openhab-addons: [deCONZ] Window Covering not working

Device: MoesHouse/Tuya AM43 Blinds Drive via deCONZ is not working

Expected Behavior

Clicking UP or DOWN should make the blinds drive move.

Current Behavior

When I click DOWN, I can see the following in the logs:

2021-05-28 18:47:13.752 [TRACE] [internal.handler.DeconzBridgeHandler] - Sending {"on":true,"ontime":0} via http://10.0.0.99:80/api/0D234FD02F/lights/6/state
2021-05-28 18:47:13.757 [WARN ] [ernal.handler.DeconzBaseThingHandler] - Sending command DOWN to channel deconz:windowcovering:000000000000:847127fffe1aa5d901:position failed: 400 - [{"error":{"address":"/lights/6/state","description":"parameter, ontime, not available","type":6}}]

And nothing happens.

If I click UP, I can see the following:

2021-05-28 19:00:23.708 [TRACE] [internal.handler.DeconzBridgeHandler] - Sending {"on":false} via http://10.0.0.99:80/api/0D234FD02F/lights/6/state
2021-05-28 19:00:23.731 [TRACE] [ernal.handler.DeconzBaseThingHandler] - Result code=200, body=[{"success":{"/lights/6/state/open":true}}]

And besides the successful message, and the blinds being closed/down, nothing happens.

Possible Solution

According to a deCONZ member on https://github.com/dresden-elektronik/deconz-rest-plugin/issues/4942 ontime is not a supported parameter on their API.

Steps to Reproduce (for Bugs)

1. Create a item like below

  "LivingRoomBlinds": {
    "class": "org.openhab.core.items.ManagedItemProvider$PersistedItem",
    "value": {
      "groupNames": [
        "LivingRoom"
      ],
      "itemType": "Rollershutter",
      "tags": [
        "Blinds"
      ],
      "label": "Living Room Blinds",
      "category": "Rollershutter"
    }
  },

1. Connect it to the windowcovering thing in deCONZ
2. Hit UP or DOWN commands.
