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.

Can I get my Pico paddle remote to dim?
No, The Pico paddle remote works the same as the Pico 2B smart remote. The only exception is that when paired with a Diva Dimmer a single press of the Pico Paddle Remote will take the light level to the slider level of the dimmer, a second press takes the dimmer to high end. (A firmware update may be required to your Diva smart dimmer through the Lutron App)
- Can the firmware update be done in pro mode?
- Can the Pico paddle remote be used to control scenes?
- Can you set the light on the Pico paddle remote as a night light?
- Do I need a Caséta smart hub to use a Pico paddle remote?
- Does the Pico paddle remote work with other Pico accessories such as the Pico pedestal and the Car Visor Clip?

How can I tell if the firmware of my Diva smart dimmers needs to be updated?
In your app, go to settings. In the menu options, you should see an option for Firmware Update. If there is a red dot next to Firmware update, this means you have devices that require an update. Select Firmware update. The next screen will show devices that require a firmware update. If none are listed, then your devices connected to your Lutron smart hub are currently up to date.

How does the new processor work with RadioRA 3?
The new all-in-one processor combines the functionality of the RadioRA 2 main repeater and Connect bridge to enable control from the Lutron app, wall controls, Pico remotes and integrated voice assistants. The processor is powered by PoE (via CAT5e, or better, Ethernet cable). This allows for the processor to be centrally located within the home for optimal RF coverage. The processor supports integrations with other connected brands for a truly customized solution and can control up to 200 Lutron devices.
- I just paired a Pico Paddle Remote to a previously installed Diva Digital Dimmer and when I press the paddle remote the light goes to full on rather than the slider level. What should I do?
-
If my Pico paddle remote is added to a Caséta smart lighting control system with a smart hub and the smart hub loses power, will my Pico paddle remote still work?
A smart hub is not required for the Pico paddle remote to work; however, you can add it to a Caséta smart hub. Once a Pico paddle remote has been added to a Caséta system, the Pico paddle remote does not require internet, but it does require power to the smart hub.
-
What do I need to know about Power over Ethernet and the new system processor?
At a high level, PoE is simply a set of standards involving the use of Ethernet cable to pass power from a supply to a connected device in addition to the traditional function of the cable which is to carry communication data in a network. While there are multiple standards, the RadioRA 3 processor can be powered using either the original standard of PoE, IEEE 802.3af-2003, or PoE+, 802.3at-2009. The PoE power is typically either generated by a PoE compliant switch where both power and communication are provided from each port directly or using a PoE injector which is used to power a PoE device on a network that uses standard, non-PoE switches.

What happens if the Pico paddle remote is paired with a Diva smart diva and an Original Caséta dimmer?
If both lights are off, with one tap the lights connected to the Diva smart dimmer will go to the level indicated on the slider and the lights connected to the original dimmer will go to 100%. A second tap will bring the lights on the Diva smart dimmer to 100%. If the lights on the Diva smart dimmer are already on, then the lights will go to 100%.
-
What happens if the Pico paddle remote is paired with multiple Diva smart dimmers?
If the Diva smart dimmers are in the off position, a single tap will set the lights of each dimmer to the levels indicated on their respective sliders. A second tap will turn all connected dimmers to 100%.
