Hardware

What are the electrical characteristics of the Gateway? 

  • The Gateway is a PoE Power Class 1 device and must be powered over PoE. See the Gateway Spec Sheet.

What is the power drawn by the Gateway in different modes?

  • As a Power Class 1 device, the Gateway will always consume less than 3.8W of power.

What wired network speeds does the Gateway support?   

  • For Gateways on  Firmware 2.8.x or earlier, the Gateway does not have auto-negotiation and will require the switch to be set to 10 Mbps Full-Duplex to operate properly. For Gateways with Firmware 3.2.1 and later, the Gateway supports auto-negotiation.

Do you assign unique MAC addresses based on a block assigned to your company? 

  • Yes, Enlighted has its own block of assigned MAC addresses.

Does the device have a PoE/PoE+ version that supports 802.3bt

  • The Gateway is a PoE Power Class 1 device and does not require any additional power beyond 3.8W.

Does the Gateway incorporate or have the capability to include hardware-based security elements? 

  •  The Gateway has internal AES-128 encryption support in hardware.

How do I know if the Gateway is ready for programming?

Can the Gateway be installed above the ceiling and in the corner because a sensor bounces a signal to another sensor and so forth?

  • Installing the Gateway above the ceiling or in a corner decreases the Gateway range to the sensors and is not recommended. More specific design guidelines can be found in the Network and IT Design Guidance section. 

Can Gateways be installed inside a building to control outdoor lighting?

  • For sensors installed outdoors, Enlighted recommends installing the Gateways outdoors for maximum coverage.

Can a Gateway be mounted outdoors without damaging it?

  • Gateway is not to be mounted outdoors. The Gateway device must be installed indoors. If an application is required for outdoor sensors, the Gateway should be mounted on an interior wall and via cable connect to any outdoor omni-directional antenna with a gain of up to 11dBi or less can be used. Refer to the article Gateway Antenna Selection Guidelines.

Where can I find the Gateway's MAC address and Serial Number?

  • The MAC address and Serial Number are printed on the Gateway label.

  • For commissioned Gateways, the MAC address is displayed in the Manage UI. Double-click the GW icon in the floor plan to see the MAC address displayed in the Gateway Details screen.

Software/Firmware

What Operating System runs on the Gateway? 

  • The Gateway runs a Linux Kernel.

Does the Gateway implement a network configuration/provisioning system? 

 Can the Gateway receive automatic over the air updates and provisioning? 

Does the Gateway have the capability to store/retain any historical trend data? 

  • No, the Gateway does not store or retain any data.

What type of user interface does the Gateway use for diagnostics and commissioning? 

  • The Gateway's status and commissioning information is available either through a separate laptop-based application or via Manage User Interface.

What type of user interface does your device provide for end-user interaction? 

Does the Gateway provide an open and documented application programming interface (API) and web services that can be consumed by third-party applications? 

  • No API access is available to the Gateway.

Does the Gateway device log all events? 

  • No. There is no event log available for the Gateway.

Can the Gateway synchronize to an NTP server? 

  • Yes

If a gateway fails, do the individual light fixtures (sensors) keep operating as a standalone unit, using the last "programming" they have (for example, how long do we have to wait to turn off if no occupant is detected, or dim to pre-set level if there is no occupancy for "x" amount of time) until the gateway is repaired/replaced?

The gateway is not needed for the sensors to run their programs according to their profiles. The gateways send programming instructions wirelessly to the sensors and collect data from the sensors for analysis and reporting via Manage. If the gateway fails, and there is a loss of power, the sensor will not execute time-of-day programs. The time will need to be acquired via the gateway to run time of day programming.

The sensors have internal memory to run the profile it was last set to. Depending on how long the downtime is, the data collected might not be sent out so there will be black holes in data. Hence, in this case, data will be lost, but lights will continue to function.


Communication, Connectivity, and Networking

Which standards does the Gateway support? 

  • Ethernet/ DHCP wired protocol to Manage, IEEE 802.15.4 wireless network.

Which wireless control system communication standards does the Gateway use at physical/data link and network layers? 

  • The Gateway implements an 802.15.4 physical layer, while the data link and network layers are proprietary.

If the Gateway has wireless connectivity, does it support WPA2 enterprise and connecting to a hidden SSID? 

  • No, the does not support any WiFi protocols.

Which wired or wireless building control system communication protocols does the Gateway use? 

  • No building control protocols are supported by the Gateway.

Does any information enter or leave the Gateway via any other (including proprietary) protocols? 

  • The over-the-air protocol to the sensors and other devices is an Enlighted proprietary protocol.

Do Enlighted Gateways support IPV6?

  •  No. Enlighted Gateways do not support IPV6.

What are the possible blockers for gateway signals? (cinder block, sheetrock, wood, glass, gypsum, sheet rock, etc.) Is the Gateway's performance affected.

Metal and cement are some of the worst, but ultimately all solid materials can have an impact. Consider various factors such as the thickness of the rock wall between the signal source and the receiver, physical structure of the wall, etc. Gateways should be mounted to the ceiling with the antenna facing downwards, free and clear of all materials. Connect no more than 100 sensors per gateway, and all sensors should be within 150 feet from the Gateway. However, it all depends on the number of walls and the material they are made of.  

Enlighted IoT system’s wireless communication is based on 2.4GHz Bluetooth or Wi-Fi radio communication physical layer standards. So, the Gateway, sensors and all  wireless devices follow the conditions and limits set forth by the Bluetooth and Wi-Fi standards. Users of Bluetooth or Wi-Fi radios will observe the same transmission characteristics for all Enlighted wireless devices. 

Note: For Where application, connect no more than 50 sensors per gateway.


Network Security

Enlighted wireless encryption is AES 128-bit. Can you do 256-bit encryption?

Does the Gateway implement certificate or API based authentication to access the data through the web services API? 

  • Only certificate-based security to connect with Manage is available. APIs are not supported for Gateway access.

Does the Gateway support authentication through the exchange of keys during device provisioning, and is this certificate-based authentication?

  • Yes, this is done during the commissioning process.

Does the Gateway support TLS encryption on a shared medium networking stack (e.g., Ethernet, WiFi) 

  • TLS 1.2 supported over the Ethernet connection

How is authentication/access to configuration settings and firmware updates managed? 

  • They are initiated via Manage over a secure link.

Does your Gateway communicate with any external services (e.g., phone-home functionality or update services) 

  • The Gateway can only communicate with Manage, Enlighted Sensors, and Enlighted's EmConfig commissioning tool.

If the Gateway uses non-IP wireless technology how is information exchanged between the network interface (wired or wireless) from the non-IP wireless communications? 

  • The gateway provides protocol translation between IP on the wired Ethernet PoE interface and the 802.15.4 interface protocol layers created by Enlighted.
