This is what Tridium is all about ...

Wireless communication (EnOcean, ZigBee) and end-devices! With wireless networking between controllers (ZigBee mesh), CAN2GO™ reduces the number of devices and gateways required for building automation projects.
CAN2GO™ enables massive savings on installation labor related to wiring, conduits and wall opening/closing.
CAN2GO™ controllers have embedded BACnet and can manage metering, HVAC and lighting at the same time which, reduces building automation hardware costs.
The CAN2GO™ web interface is hosted by the controllers themselves which can provide significant savings on software and/or servers.
With savings on labor, hardware and software, CAN2GO™ delivers faster system installation, integration and payback for facility managers.
