Abstract
Wireless transceivers connect with or in building automation components. The components are bound. Since the transceivers control the access media, the transceivers are likewise bound. The transceiver associated with a component queries the component for the component address. When a request from a controller addressed to the component is received, the transceiver for the component may recognize the component address. In response, the transceiver records the controller transceiver address in the request and transmits a response with the component transceiver address. Other features may assist in binding. For example, the controller transceiver distinguishes between components connected by wire from wireless. Only communications for wireless connections are transmitted. For example, if a binding is not used for an amount of time, the binding is removed. For example, a random or set order is used to avoid or minimize overlapping traffic for the responses for a binding list.
