A second network node device for controlling an execution of technology specific Push Button Configuration sessions within a heterogeneous or homogeneous wireless network, with a plurality of further network node devices authenticated or unauthenticated for the network or not part of the network, including an authenticated first network device, an unauthenticated third network node device triggered by a virtual or physical Push Button Event assigned to the third network node device to start a technology specific Push Button Configuration session and an unauthenticated external device not being part of the network triggered also by a virtual or physical Push Button Event assigned to the external device to start a Push Button Configuration session the external device, creating a first configuration setup session identifier for identifying a specific configuration setup session and sending within the started Push Button Configuration session the created first configuration setup session identifier via at least one wireless message to the third network node device, interconnected to each other via at least one interface and/or over multiple hops, the second network node device being authenticated for the network and comprising:
- (a) a wireless transmitter device programmed to send/receive information and/or messages, the wireless transmitter device programmed to receive a notification message notifying about a further virtual or physical Push Button Event directly or indirectly from the first network node device, and
- (b) a control unit including software stored in non-transitory computer-readable media and executable by a processor to control the execution of technology specific Push Button Configuration sessions, wherein the control unit is connected with the communications unit and programmed to:
- (b1) start a Push Button Configuration session,
- (b2) during the started Push Button Configuration session, send the received configuration setup session identifier to the third network node device via at least one wireless message, to enable the third network node device to detect a session overlap as a result of determining that the first configuration setup session identifier does not match a further configuration setup session identifier received at the third network node and identifying a further specific configuration setup session, and in response to detecting the session overlap based on the non-matching configuration setup session identifiers, to abort the technology specific Push Button Configuration and technology specific Push Button Configuration session with the second network node device and the external device.
