Building equipment access management system with dynamic access code generation to unlock equipment control panels

A method for controlling access to building equipment, the method comprising:

• generating, by a device of building equipment, a device identity code identifying the device of building equipment;
• receiving, at an access manager platform, an access request from a user device to access the device of building equipment, the access request indicating the device of building equipment to which access is requested and an identity of an entity requesting the access;
• selecting, by the access manager platform, an access level of the entity from a plurality of access levels stored in an access profile database based on the identity of the entity requesting the access and the device of building equipment to which the access is requested, wherein the plurality of access levels correspond to a plurality of different predetermined sets of functions of the device of building equipment to which access can be granted;
• generating, by the access manager platform, an encrypted access code indicating the access level of the entity, wherein the encrypted access code is generated based on the device identity code;
• transmitting, by the access manager platform, the encrypted access code to the user device in response to the access request, the encrypted access code granting access to the device of building equipment and permitting the entity to access the plurality of different predetermined sets of functions of the device of building equipment corresponding to the access level when the encrypted access code is entered via a device interface of the device of building equipment;
• decrypting, by the device of building equipment, the encrypted access code using a security key stored in the device of building equipment to determine the access level of the entity to the device of building equipment indicated by the encrypted access code;
• and
• granting, by the device of building equipment, access to a predetermined set of functions of the device of building equipment corresponding to the access level by making the predetermined set of functions accessible to the entity via the device interface.

One or more non-transitory computer-readable media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• generating, by a device of building equipment, a device identity code identifying the device of building equipment;
• receiving, at an access manager platform, an access request from a user device to access the device of building equipment, the access request indicating the device of building equipment to which access is requested and an identity of an entity requesting the access;
• selecting, by the access manager platform, an access level of the entity from a plurality of access levels stored in an access profile database based on the identity of the entity requesting the access and the device of building equipment to which the access is requested, wherein the plurality of access levels correspond to a plurality of different predetermined sets of functions of the device of building equipment to which access can be granted;
• generating, by the access manager platform, an encrypted access code indicating the access level of the entity, wherein the encrypted access code is generated based on the device identity code;
• transmitting, by the access manager platform, the encrypted access code to the user device in response to the access request, the encrypted access code granting access to the device of building equipment and permitting the entity to access the plurality of different predetermined sets of functions of the device of building equipment corresponding to the access level when the encrypted access code is entered via a device interface of the device of building equipment;
• decrypting, by the device of building equipment, the encrypted access code using a security key stored in the device of building equipment to determine the access level of the entity to the device of building equipment indicated by the encrypted access code;
• and
• granting, by the device of building equipment, access to a predetermined set of functions of the device of building equipment corresponding to the access level by making the predetermined set of functions accessible to the entity via the device interface.
