I am just reading the doc of the binding again. Here it says:
If the actuator supports UTE teach-in, the corresponding thing can be created and paired automatically. First you have to start the discovery scan for a gateway. Then press the teach-in button of the actuator. If the EEP of the actuator is known, the binding sends an UTE teach-in response with a new SenderId and creates a new thing with its channels.
To me, that sounds like the binding (aka via the USB300 stick) should send the telegram to the acuator in teach-in mode. Does not work, however. Although my actuators support UTE teach-in
