This diagram of the smart building tech stack is by Rob Huntington at emeseye (prounounced MSI, i.e. Master Systems Integrator). That gives an idea of where Rob is coming from. It is akin to the one from James Dice and his Nexus Labs community I shared earlier (see here), but is slightly more vertical and includes cybersecurity is another layer/important consideration. It also helps better explain what is going on in the data layer and what’s needed given all the different protocals being used – particularly by all the Operational Technology at the Connected Device Layer.
