A communication module for a building technology device, especially a luminaire, is provided, wherein the communication module is configured to be connectable to an IoT-network and a communication bus, and being configured for a bi-directional communication on the IoT-network and the communication bus, wherein the communication module is configured to convert communication data between the communication bus and the IoT-network.

A disclosed method includes establishing a secure authenticated network connection between an apparatus located at an emergency communication center (ECC) location and operatively coupled to an ECC functional entity, and an application programming interface (API) endpoint in the cloud; performing an authentication procedure between the apparatus and the application programming interface (API) endpoint in the cloud upon establishment of an internet connection to the apparatus; obtaining data from the functional entity by the apparatus and appending ECC identification information; sending the data as packet data comprising the ECC identification information to the API endpoint; and providing a portal graphical user interface to at least one ECC entity that displays enhanced emergency call data using the packet data.
