Building automation systems for online, offline, and hybrid licensing of distributed edge devices

A method for licensing devices in a building space, the method comprising:

• generating, by an HVAC device, an encrypted dynamic key based on a manifest stored on the HVAC device, wherein the manifest comprises a set of entitlements for the HVAC device based on relationships between the HVAC device and entities;
• transmitting, by the HVAC device, the stored manifest to an authentication server by sending the encrypted dynamic key to the authentication server;
• receiving, by the HVAC device, an updated manifest from the authentication server based on the encrypted dynamic key;
• and
• sending, by the HVAC device, a payload request to the authentication server based on the updated manifest, wherein the payload request comprises a software update request.

A heating ventilation and air conditioning (HVAC) device for a building space, the device comprising:

• a processing circuit is configured to:
• generate an encrypted dynamic key based on a manifest stored on the HVAC device, wherein the manifest comprises a set of entitlements for the HVAC device based on relationships between the HVAC device and one or more entities, wherein the relationships between the HVAC device and the entities comprises relationships between one or more group entities and the HVAC device, user entities and the HVAC device, and device entities and the HVAC device;
• transmit the stored manifest to an authentication server by sending the encrypted dynamic key to the authentication server;
• receive an updated manifest from the authentication server based on the encrypted dynamic key;
• and
• send a payload request to the authentication server based on the updated manifest, wherein the payload request comprises a software update request.
