I also followed the same way you did. connection: "topics": [ "_/_/things/twin/events?filter=and(like(thingId,'org.eclipse.ditto:myThing:*'),exists(features/lamp))&extraFields=thingId,features/water-tank/properties,attributes/location" ], PUT /api/2/things/org.eclipse.ditto:myThing:123/features/water-tank I tried both put and patch payload: { "properties": { "foo": "bar" } } but...

No, I have only one connection.
