Let's break down your questions about the Maestro switches

1. Are Maestro switches from 2010 still sold pretty much as they were back then?
No, not exactly. While the core functionality of dimming and switching probably remains similar in current Maestro models, there have been refinements and new features added over the years. Lutron (the manufacturer of Maestro) is constantly improving their products. Some of the biggest differences would be in LED compatibility and smart home integration.2. Would they have been LED compatible at that time (around 2010)? Potentially, but with caveats. In 2010, LED technology was still relatively new in residential lighting, and compatibility with dimmers was a major issue. Lutron did have dimmers designed to work with LEDs back then, but the compatibility wasn't as broad or reliable as it is today. Important Considerations



Specific Model

The exact model number of the Maestro switch is crucial. Some specific Maestro models around that time were designed with some LED compatibility in mind.

LED Bulb Quality

The quality of the LED bulbs themselves played a huge role. Cheap, poorly designed LED bulbs were (and sometimes still are) prone to buzzing, flickering, or not dimming smoothly even with a compatible dimmer.

Minimum Load

Older LED-compatible dimmers often required a minimum load to operate correctly. If the combined wattage of the LED bulbs was too low, the dimmer wouldn't function properly, even if the bulbs were theoretically "compatible."

3. Looks like some of them are "multi-position" used without a traveler. Is this tech still used? Yes, this technology is absolutely still used and very common, even more so now! You're likely referring to a "digital" multi-location setup. How it works

Instead of using a traditional traveler wire (a dedicated wire running between the switches), these systems use a low-voltage signal sent over the existing wiring to communicate between the master dimmer and the companion switches. It eliminates the need for dedicated traveler wires.

Lutron's Terminology

Lutron often refers to these as "Companion" dimmers/switches.

Why it's popular



Easier Installation

It simplifies wiring, especially in older homes where running new wires is difficult.

Flexibility

You can add multiple control locations without needing to run additional traveler wires.

Smart Home Integration

These systems often integrate better with smart home hubs and automation.

In Summary

The Maestro switches from 2010 might have some LED compatibility, but performance could be spotty with modern LEDs.* The multi-position (companion) technology you described is still widely used and has improved significantly.

Recommendations


Identify the Exact Models

Look for model numbers on the switches themselves (usually on the faceplate or on the side). With the model number, you can search Lutron's website or online documentation to determine the original specifications and LED compatibility.2.

Test with Modern LEDs

If you're having issues with LED dimming, try replacing the older LEDs with newer, higher-quality LEDs that are specifically designed for dimming. Lutron often provides a list of tested and compatible bulbs on their website.3.

Consider Upgrading

If you're experiencing significant problems with LED dimming or want to take advantage of smart home features, consider upgrading to newer Maestro models or other Lutron dimmer options. Modern dimmers have far better LED compatibility and often offer features like scene control, timers, and app-based control.4.

Consult an Electrician: If you're unsure about the wiring or compatibility, it's always best to consult a qualified electrician. Flag for review
