How do I find my Model Number?
Do you have the original packaging?
-
If your product came in plastic packaging (a clamshell), you’ll find the model number on the front of the insert card, on the lower left corner. If your product came in a box, you’ll find the model number on the top of the box.
Most model numbers are 12-16 characters and start with a couple letters followed by a dash.

No packaging? No problem!
-
The product number is on a label on the side of the dimmer or switch.*
If you’ve already installed the dimmer/switch, turn off the electricity and then remove the wallplate. Unscrew and remove the wallplate adapter, then unscrew the dimmer/switch and pull it out of the wall until you can see the label.
*Please note: The product number for Ariadni/Toggler dimmers is not on a label. It’s located directly on the front of the dimmer on the top left, or right below the on/off toggle.

Line Voltage QS Device Not Responding (ESN)
Explanation: The Lutron processor is unable to communicate with the device. This could be due to one of 3 reasons.
- The device is malfunctioning.
- The low voltage communication cable has been disconnected or damaged.
- line-voltage has been removed from the device and it is powered down.
Diagnose:
- Locate the device
- The different panel options are listed here Athena System Architecture & Controls | Lutron
- Confirm device is powered on
- The device should have LEDs on/flashing to indicate power.
- If there is no power, this is the source of your problem, please provide power to the device.
- Locate the device
Fix:
- If the device is powered on, then scroll to the bottom of the page and request support. Please locate your system name and/or job number as well as saying you are diagnosing a QS device nor responding for [inset model number]. You have confirmed power, but the LEDs are displaying [describe behavior].

- Daylight Sensor (model number LRF2-D*)-CR2450
- Model numbers will vary with regions outside of North America
-
Low Voltage QS Device Not Responding (all other QS devices)
Explanation: The Lutron processor is unable to communicate with the device. This could be due to one of 3 reasons.
- The device is mal functioning.
- The low voltage communication cable has been disconnected or damaged.
- Line-voltage has been removed from the upstream device that is powering this device and this device is powered down.

Processor Offline
Explanation: Lutron Connect cloud services are not able to communicate with the processor on your site. This will be impacting alerting, energy and occupancy data gathering, control via software, remote support and other cloud services. If the processor is disconnected from the internet, this will not impact day to day functionality of the system. This could be indicative of a powered down processor or a faulty device. If this is true, this would have an impact on wall controls, sensing, and scheduled events, and it should be addressed immediately.
Diagnose:
- Locate the device
- Q-RF and A-RF2 (wireless processors) are likely installed on a ceiling
- All others (QP6, QP5, QP-1L, and QP-2L) are electrical panels or will be located inside of a panel
- The different processor options are listed here - Athena System Architecture & Controls | Lutron
- Confirm device is powered on
- The processor should have LEDs on/flashing to indicate power. The wireless processors will only flash once per minute.
- If there is no power, this is the source of your problem, please provide power to the device.
- If powered on, what is the LED doing?
- Blinking yellow-There is a network issue between the processor and the internet.
- Something else-There is some other problem that will need Lutron support.
- Locate the device
Fix:
- If blinking yellow, note the MAC address and send an email to your IT administrator requesting internet access. Also provide www.lutron.com/athenaitguide to answer any technical questions.
- If blinking any other colors, scroll to the bottom of the page and request support. Please locate your system name and/or job number as well as saying you are diagnosing a processor offline for [inset model number]. You have confirmed power, but the LEDs are displaying [describe behavior].
