    Abstract: A heating ventilation and air conditioning (HVAC) system for a building space includes an HVAC device including a processing circuit. The processing circuit is configured to generate an encrypted dynamic key based on a manifest stored on the device. The manifest includes a set of entitlements for the HVAC device based on relationships between the HVAC device and entities. The processing circuit is further configured to transmit the stored manifest to an authentication server by sending the encrypted dynamic key to the authentication server and receive an updated manifest from the authentication server based on the encrypted dynamic key. The processing circuit is further configured to send a payload request to the authentication server based on the updated manifest, the payload request including a software update request.

    Abstract: A smart circuit breaker is configured for installation within a panel assembly. The smart circuit breaker includes a breaker device positioned between a power source and a subcircuit, the breaker device having a moveable contactor configured to change from an open state to a closed state, wherein in the closed state power flows from the power source to the subcircuit via a power line, and wherein in the open state power does not flow from the power source to the subcircuit. The smart circuit breaker further includes a power meter configured to measure a power characteristic of the subcircuit. The smart circuit breaker further includes a processing circuit configured to receive a power characteristic measurement from the power meter, the processing circuit having a communications interface configured to communicate power consumption data to an external device, the power consumption data based on the power characteristic.
