The first Caséta Plug in Lamp dimmer (PD-3PCL) will act as a 30 foot range extender when added to the Caseta system. If you have added multiple PD-3PCL to your system and you need to find out which is acting as the range extender, please follow the guide below.
Note: The plug-in dimmer that is assigned as your range extender is listed in the Lutron App under "Settings>Advanced". Once a plug-in dimmer is assigned as a range extender it must be removed from the system if you want a different plug-in dimmer to be assigned as the range extender.
