Web-based interaction with building automation is provided. The interaction, regardless of the access point, is browser based. For IP access, hypertext protocol (http) communications of the browser are performed. The web-enabled controller serves responses with building automation information. For non-IP access, a web-server operating as an application in the same device as the browser intercepts the http communication and reformats the communication as appropriate for the non-IP access. Based on a response from the building automation system, the device local web-server responds to the browser. For communicating across different types of networks in the building automation system, controllers may use the embedded web-server to reformat as needed and route requests. The same look, feel, functionality, and/or usability may be provided using the browser regardless of the connectivity to the building automation network.

Web-based interaction with building automation

An apparatus and methods provide a building automation system that includes a controller, a web server and a client. The controller includes building automation objects that may be used to generate a model that includes elements, wherein each element is associated with one or more of the objects. The web server includes business logic that reads and subscribes to the objects. Each object notifies the business logic of changes to the data of the object. The business logic processes the data from the objects to provide model update commands based on the changed data. The client includes presentation logic that displays the model, receives the model update commands from the business logic, updates the model using the model update commands, and displays the updated model.
