For providing data of an apparatus for applications, routing of the data via a communication node is provided. In this case, the apparatus communicates the data wirelessly to the communication node. This necessitates pairing the apparatus with the communication node beforehand, which is carried out with the aid of an installation key. The data transfer itself is then secured with a connection key defined during the pairing. If replacing or reconnecting the communication node necessitates carrying out re-pairing, at least one criterion relating to the reachability of the communication node is checked and the lack of reachability as per the criterion is made into the prerequisite for using the installation key instead of the connection key for re-pairing. At least one embodiment of the invention increases protection against interferers wanting to access the apparatus in an unauthorized manner.
