A method for evaluating at least one drive parameter of at least one associated door system, wherein at least one interface unit and at least one evaluation unit are provided in a storage system, wherein the following steps are performed: - receiving the at least one drive parameter through the interface unit, wherein the drive parameter is specific to the associated door system, - storing the received drive parameter in the storage system so that the drive parameter is assigned to the associated door system, - performing at least one evaluation of at least one first piece of information of the stored drive parameter and at least one further piece of information of at least one further drive parameter through the evaluation unit, wherein the at least one further drive parameter is specific to at least one further door system, - providing different evaluation functions for at least one of the door systems based on the at least one evaluation, wherein the evaluation functions are each correlated with the at least one first piece of information and with the at least one further piece of information, wherein at least one of the evaluation functions is performed to evaluate at least one of the door systems, and is performed to determine at least the following evaluation information: - a functional status of the at least one door system, namely maintenance information about at least one upcoming maintenance, at least based on information of the at least one drive parameter about a service life and/or a service cycle in the at least one door system, based on a prediction calculation, wherein the at least one of the evaluation functions is additionally performed to determine information about a location of the at least one door system, in particular so that geographical map information is provided; wherein a plurality of different pieces of information of the same and/or different drive parameters are stored in the storage system and evaluated with one another, in particular correlated and/or compared, for the provision of respective evaluation functions, so that conclusions can be drawn about maintenance information based on the drive parameters and/or information, characterized in that the different pieces of information comprise the following information: - weather information specific to a location of the associated door system, - maintenance information, preferably information about a maintenance status and/or a maintenance date and/or a time of initial commissioning and/or a defect in the associated door system. - receiving the at least one drive parameter through the interface unit, wherein the drive parameter is specific to the associated door system, - storing the received drive parameter in the storage system so that the drive parameter is assigned to the associated door system, - performing at least one evaluation of at least one first piece of information of the stored drive parameter and at least one further piece of information of at least one further drive parameter through the evaluation unit, wherein the at least one further drive parameter is specific to at least one further door system, - providing different evaluation functions for at least one of the door systems based on the at least one evaluation, wherein the evaluation functions are each correlated with the at least one first piece of information and with the at least one further piece of information, wherein at least one of the evaluation functions is performed to evaluate at least one of the door systems, and is performed to determine at least the following evaluation information: - a functional status of the at least one door system, namely maintenance information about at least one upcoming maintenance, at least based on information of the at least one drive parameter about a service life and/or a service cycle in the at least one door system, based on a prediction calculation, - a functional status of the at least one door system, namely maintenance information about at least one upcoming maintenance, at least based on information of the at least one drive parameter about a service life and/or a service cycle in the at least one door system, based on a prediction calculation, wherein the at least one of the evaluation functions is additionally performed to determine information about a location of the at least one door system, in particular so that geographical map information is provided;
