Ketra Scenes
Only one Ketra group can be controlled at a time. This is good for certain applications, like when a dining scene is set to control Ketra lights only within the “Dining Room” group.
If the dining scene is to control lights within the “Dining Room” and “Kitchen” groups, a separate Control Group named “Dining Room + Kitchen” should be created.
App Control
Create virtual keypads in Lutron Designer to be used in the Lutron Connect app. When building a Ketra and HomeWorks QS installation, virtual keypads have been removed from Ketra Design Studio.
Customers will be able to access physical keypad buttons in the Lutron Connect app, but they may desire additional control. Consider creating virtual keypads with buttons that change group settings. This will provide control of intensity, correlated color temperature, tint, vibrancy, and the full gamut of color settings.
Remote Access
HomeWorks QS systems and Ketra installations can be accessed remotely. It is recommended that remote programming be reserved for system tweaks like changes to keypads button programming and scene settings. More substantial actions like firmware updates or lamp commissioning should be performed on site.
Lutron recommends using a VPN connection for remotely programming a HomeWorks QS system. For more information, refer to Application Note #231 (048231) at www.lutron.com.
It is possible to Publish to a Ketra system remotely. To enable this option, navigate to Settings > Enable Remote Access in the Ketra Design Studio. Enabling remote access must be done while connected to the same local network as the installation.
Upgrading an Existing Ketra Installation
If the Ketra Design Studio installation was created with a software version older than 3.0, it cannot be added to a HomeWorks QS system. Additional actions are needed. Follow the steps below to decommission and update all Ketra products so that the can be added to a new HomeWorks QS installation.
1. Use the Ketra Tech Tool to update the firmware in all Ketra devices to version 2.0 or later.
2. Open the existing installation in the Ketra Design Studio and click Delete Installation. This will decommission all the Ketra devices.
3. Create a new Ketra with HomeWorks QS installation. Follow the system design and commissioning practices explained previously in this document.
Lutron Button Type and LED Logic
Button Type: Single Action
LED Logic: Scene
This should be used for buttons that correlate with daily activities or moods (e.g., dining, watching TV, reading, relaxing). When a keypad contains these buttons, the customer should be provided with an “Off” button at the bottom of the keypad. Each button press or input action will typically trigger the same output action when using normal programming.
Scene LED logic means that all affected lighting zones, Ketra groups, and shades need to be at their programmed level for the status LED to be on. Changing the level of any of the affected devices will cause the LED to turn off.
Button Type: Toggle
LED Logic: Room
This should be used to turn on/off zones or groups with one button (e.g., pendants, main tracks, basement). “Press on” action typically turns on affected lights to a programmed level. “Press off” action either turns off affected lights or dims them to a low light level.
Room LED logic means that the status LED will be on if any of the affected lights in the area are on at any light level. If the status LED is on, the next button press will trigger the “Press off” action. If the status LED is off, the next button press will trigger the “Press on” action.
Button Type: Single Action or Toggle
LED Logic: Pathway
This should be used for creating a path of light from one area to another (e.g., midnight snack, bathroom). The status LED will be on if affected Lutron lighting zones are on at any level. The status LED will turn off if any of the affected zones are turned off.
Pathway LED logic functions differently when Ketra groups are included. The status LED uses scene LED logic for any Ketra groups. If the settings of the affected Ketra group change at all, the status LED will turn off.
Button Type: Single Action
LED Logic: Room
Not Recommended
Button Type: Toggle LED
Logic: Scene
Not Recommended
Double Tap Programming: If both the press and the double tap include Ketra groups, the Ketra lights will incur a delay (about 1 second) on the double tap due to the propagation of the first command.
Automatic Sequences: Due to the 1.5 second delay between Ketra commands, automatic sequences for Ketra scenes should not be run faster than 1.5 seconds per step.
