General Troubleshooting

Controller Status Indicator LED Colors

The controller's LED status indicator can help troubleshoot or diagnose an issue.

• Solid Green: Controller is powered and ready, load is turned off.
• Solid Red: Controller is powered and ready, load is turned on.
• Blinking Green: Waiting to receive signal for switch pairing or controller grouping.
• Blinking Red/Green: Received pairing/grouping signal, waiting to confirm.
• Rapid Green Flash Followed by Solid Green: Successfully saved pairing or grouping.
• Flashing Red/Green/Yellow: Failed firmware update, please contact Levven Support.

Switch Only Turns On One Controller

To control multiple grouped controllers with a single switch, you must pair the switch to each controller individually. 

For example, if you have one switch and two controllers, please group the controllers and then complete the pairing process twice—once with the first controller and again with the second.

Resetting a Controller 

Controller memories can be reset to a factory default state. 

Resetting the controller's pairing list clears the list of switches that the controller was paired with. This is useful when you want the controller to stop responding to its original switch and start listening to a different switch.

Resetting the controller's group info makes it forget the group that it was added to. This is necessary if you want to take the controller from one installation and use it in a different house.

Resetting Switch Pairings

To clear the controller's switch pairing data: 

1. Press and hold the button on the controller for five seconds. 
2. After five seconds, the controller's LED will flash RED three times. The flashing LED indicates that the switch pairing has been reset. 
3. Let go of the button.

Factory Reset (Clear All Pairing and Group Data)

Factory resetting the controller will return it to its default settings and clear all pairings and groupings.

1. Press and hold the button on the controller for ten seconds. 
2. After five seconds, the LED will flash RED three times. Continue holding the button. 
3. After 10 seconds, the LED will flash RED 10 times to signal that the controller's memory has been fully reset. 

Dimmer Troubleshooting

Light Fixture Flickers

Flickering can happen when your brightness levels are set too high or too low for your light fixture to work properly. Light fixtures and bulbs require a minimum power level through the circuit.

If your light is flickering with your dimmer, check that the fixture and its bulbs are rated as "dimmable".

If the flickering occurs at full brightness, it is possible that the light may be reaching the end of its lifetime and beginning to burn out.

If the flickering occurs at some (but not all) brightness levels then utilizing the controller's settings may help.

Setting the min/max levels of your controller will prevent the flickering by adjusting the lowest and highest brightness setting of your light fixture. 

Set the Dimmer Maximum Brightness Level

1.  Use the switch to set the dimmer to the maximum desired brightness.
2. 1. If the light flickers, release the switch and press and hold the down/off button on the switch to dim until flickering stops.  
3. Double-click the GPDT15 controller’s button to set the max brightness (press the button twice in quick succession).  
4.  The controller’s LED will flash green to confirm. 

Set the Dimmer Minimum Brightness Level

1. Press and hold the down/off button on the switch to dim the light. 
2. 1. If the light flickers, press and hold the up/on button on the switch until it stops flickering.  
3. Double-click the GPDT15 controller’s button to set the lowest brightness (press the button twice in quick succession).    
   
4.  The controller’s LED will flash green to confirm. 

Reset the Dimmer's Min/Max Brightness to Factory Settings

1. Triple-click the GPDT15 controller’s button (press the button three times in quick succession).
2. This operation will reset min/max brightness settings, but the controller's pair and group data will remain.

Switch Troubleshooting

What does the LED light on the switch mean?

• When paired with a controller, the switch's LED flashes when pressed, confirming successful communication.
• If the battery is getting low, the LED will flash multiple times to indicate that it's time to change the battery.

My Switch Does Not Work

1. Check the LED light on switch
2. • No Blinking LED – Switch may need to be paired to the controller
   • Rapid Blinking LED after switch press - Battery is low. Change the battery.
3. Check the pairing
4. 1. Re-pair the switch to desired controller.
   2. Move switch closer to controller and repeat previous step. 
   3. If you have a Levven Q gateway, open the Levven app and press the wall switch. If it doesn’t highlight in the app, it may not be connected. Try re-pairing it. 
   4. Pair the switch with a different controller. If the switch works with the new controller, the original controller is faulty. 
   5. Pair a different switch with the desired controller. If a new switch works with the controller, the original switch is faulty. 

Switch Only Turns On One Controller

To control multiple grouped controllers with a single switch, you must pair the switch to each controller individually. 

For example, if you have one switch and two controllers, group the controllers together first, then complete the pairing process twice—once with the first controller and again with the second. 

How to Clean the Switch

• Use a damp cloth and wipe over the switch until dirt is removed 
• AVOID using solvent cleaners, spray cleaners, or excessive water 

* Switches are not waterproof and may be damaged, voiding the warranty. 

Replacing the Battery

1. Pry down the switch rocker from the top using a wood toothpick (avoid metal tools to prevent circuit board damage). 
2. Remove old battery and insert new one. 
3. Snap switch rocker back onto switch base
