What Do Deco LED Colors Mean?

The LED on your Deco unit communicates its current status through different colors and patterns. Understanding your Deco lights meaning can help you quickly tell whether everything is working normally or if something needs your attention. The most common Deco LED colors you'll see are yellow (starting up), green or white (working normally), blue (setup mode), and red (issue detected). Keep in mind that exact Deco LED colors and their meanings vary by model, so check the table for your specific unit below.

Key Takeaways

• A solid green or white LED means your Deco is connected and working normally. Which color you see depends on your model.
• A pulsing blue LED means your Deco is ready for setup. A solid blue LED means setup is currently in progress.
• A solid yellow LED means your Deco is starting up. Wait one to two minutes for the process to finish.
• A red LED indicates a problem. Your Deco has lost its Internet connection or encountered an error.
• Deco LED color meanings vary by model. Always check the table for your specific unit, and consult your model's user guide if it is not listed here.
