Lutron dimmer – Secret settings convert to a switch

You say Lutron switches, I say Lutron dimmers – no cheating!

Previously, I’ve written about the difference between a Lutron dimmer and a Lutron switch used to control lights.

I’ve also mentioned secret manufacturer codes that can be used to reset many smart home devices back to their original factory settings.

Now it’s time to bring these two different topics together.

With the appropriate use of secret “cheat code” sequences, certain plug-in dimmer modules from Lutron can be converted by the owner into on/off non-dimming switches.

This is very useful if you would like to have Lutron smart plug style on/off control of some devices that otherwise can’t be use with dimmers.

There are limitations in current and amperage supported, so tread carefully and really do read the instruction manual reference.

Don’t expect to control a window air conditioner, electric heater, or other high current / high amperage devices, but this can be useful for tabletop lamps, floor lamps, or other small appliances.

If you have decorative lights that use fluorescent bulbs, old fashioned 3-way filament lights, or other lamps that are not compatible with dimmers, you can now automate them with on/off commands.

Which Lutron dimmer systems are supported?

This only works with plug-in modules. It is not applicable to in-wall dimmers.

For Lutron Caseta, the very popular consumer lighting control solution sold just about everywhere in the US, this works with the Lutron PD-3PCL-WH plug-in lamp dimmer module.

For Lutron RA2 Select, Lutron RA2, and Lutron HomeWorks, this works with the Lutron RR-3PD-1-SW plug-in lamp dimmer module.

Here’s the magic instructions to switch between dimmer mode and switch mode for each of these devices.
