A building management system comprising:

• a plurality of devices of building equipment;
• an entity database storing a plurality of interconnected smart entities, the smart entities comprising object entities representing the plurality of devices of building equipment and data entities representing data associated with the plurality of devices of building equipment, the smart entities being interconnected by relational objects indicating relationships between the object entities and the data entities, each object entity comprising a stored attribute indicating a version of software installed on a device of the building equipment represented by the object entity;
• and
• an assurance service configured to automatically detect a version of software installed on each of the devices of building equipment by reading the stored attributes of the object entities and automatically update the software installed on one or more of the devices of building equipment in response to a determination that the version of software installed on the one or more of the devices of building equipment is not a latest version of the software.
