Network and IT Considerations
LumaWatt Pro Network Topology Options
The feature that most differentiates LumaWatt Pro Lighting Control from other wireless, networked building management solutions is the
autonomy of LumaWatt Pro Smart Sensors. Each LumaWatt Pro Sensor is a full-fledged computing and communications device that controls
light levels locally. With the bulk of control instructions transmitted over a wired connection to the control unit and ballast, traffic on the
LumaWatt Pro wireless network is kept to a minimum.
Wireless networking is used mainly for data gathering and transport of energy, environmental and occupancy data to the central LumaWatt
Pro Energy Manager™ appliance. This appliance provides an interface to the sensor network, simplifying configuration and management of
lighting behavior, as well as data monitoring and reporting.
LumaWatt Pro Smart Sensors communicate to the LumaWatt Pro Energy Manager through the LumaWatt Pro Gateway using the IEEE
802.15.4 wireless communication protocol that includes AES encryption to ensure secure links.
The LumaWatt Pro Energy Manager is (typically) mounted in a wiring or electrical closet and can be on the IT network or a stand-alone
network. The LumaWatt Pro Energy Manager’s intuitive graphical user interface can be accessed via a standard secured browser connection.
The figure below shows an example of an LumaWatt Pro Energy Manager installation in an office environment.
The section below explains the Dedicated and Network installation methods.
LumaWatt Pro Enterprise Network
• The wireless gateway and Energy Manager connects to the building IT network via PoE switch or power injector and must have access to
the building DHCP server.
• At the discretion of the building IT personnel the LumaWatt Pro system may be setup on a separate lighting network or VLAN.
• Smart devices and computers should be able to connect to the building Wi-Fi network and have access to the Energy Manager on the
building IT network or VLAN.
• Connecting the LumaWatt Pro system to the building IT enables certain features such as BACnet® integration or future smart building
integration features.
