A building control system (10) is described that includes a building controller (12, 14, 20, 252, 270, 276, 460, 466) and a bridge (16, 18, 22, 40, 254, 272, 274, 462, 464). The building controller (12, 14, 20, 252, 270, 276, 460, 466) may control one or more portions of a building control system and may communicate with the bridge (16, 18, 22, 40, 254, 272, 274, 462, 464) over a wired network. The bridge (16, 18, 22, 40, 254, 272, 274, 462, 464) may be coupled to the building controller (12, 14, 20, 252, 270, 276, 460, 466) and may be configured to communicate with other remotely located building controllers (12, 14, 20, 252, 270, 276, 460, 466) via a wireless network. The bridge (16, 18, 22, 40, 254, 272, 274, 462, 464) may provide a link between the wired communication of the local building controller (12, 14, 20, 252, 270, 276, 460, 466) and the wireless communication of the remotely located building controllers (12, 14, 20, 252, 270, 276, 460, 466). The bridge (16, 18, 22, 40, 254, 272, 274, 462, 464) may include a cache memory (32) for storing data received from remotely located building controllers (12, 14, 20, 252, 270, 276, 460, 466). In some cases, the data stored in the cache memory (32) may be requested and received in advance of the data being requested by the local building controller (12, 14, 20, 252, 270,276,460,466).
