Maintenance monitoring is an essential task in the field of preservation of historic buildings. The continuously developing IoT-based systems for monitoring already exist in many areas, like the maintenance of complicated mechanical systems or large industrial facilities, but there are only a few examples of the application of such methods in the field of cultural heritage preservation. In this paper, the possible elements and system of an automatized maintenance monitoring network are tested by analyzing the possible options of the survey units and the system to be established in cases of altering circumstances of the investigated site, highlighting the factors which have to be considered in the case of developing a network on-site. Finally, typical application cases were distinguished, and configuration options were suggested for the automated maintenance monitoring systems.
