When you turn the switch to the “ON” position it will send the command to the service to “OPEN” the door. The binding only polls the status of the door every 60 seconds and this is why you see a delay. I plan to add a “quick poll” feature that will refresh the door status quicker after a command is sent but I have not implemented it yet. The Rollershutter item is a reference to the openHAB 1.x binding. I have not tried to add this feature and the other features you mentioned to the openHAB 2.x binding.
