1. A system, comprising:

  • a building-external communication network, comprising a building-external communication server;

    a building-internal communication network, comprising a building-internal communication device; and

    an access portal device, configured to control communication between the building-external communication server and the building-internal communication device;

    wherein the access portal device comprises;

    a first memory located in the access portal device for storing authentication data for initiating a communication connection between the access portal device and the building-external communication server;

    a first communication interface with the building-external communication server for establishing communication with the building-external communication server using the stored authentication data, wherein the first communication interface is configured to monitor the communication connection between the access portal device and the building-external communication server and, in the event of a fault in the communication connection between the access portal device and the building-external communication server, to generate a fault message; and

    a second communication interface with the building-internal communication device for communicating with the building-internal communication device, wherein the second communication interface is configured to send the stored authentication data from the first memory of the access portal device to a second memory located in the building-internal communication device in response to the fault message to initiate a communication connection between the building-internal communication device and the building-external communication server;

    wherein the access portal device and the building-internal communication device are separate devices;

    wherein the building-internal communication device comprises a controllable sensor for detecting temperature data;

    wherein the first memory of the access portal device is further configured for storing a software container comprising instructions for putting the building into a sleep mode in response to temperature data detected by the controllable sensor indicating that a temperature has fallen below a threshold value, wherein the first memory of the access portal device being configured for storing the software container is based on a selection of the access portal device as being an optimal device out of a plurality of devices for storage of the software container by the building-internal communication network; and

    wherein the access portal device is configured, in the event of a fault in the communication connection between the access portal device and the building-external communication server, to relay the software container to another device of the plurality of devices for the other device to take over control tasks relating to the sleep mode of the building.
