What do the LED colours indicate on the front of the dimmer?
This article explains the meaning behind the LED status light colours found on the front of Lightwave dimmer switches. These lights provide important feedback about the device’s status during normal use, setup, and in response to any issues or alerts. Recognising these indicators helps ensure correct installation, seamless pairing, and effective troubleshooting of your Lightwave dimmers.
Lightwave Smart Dimmers use an LED light on the front of them to display their current state. These LED colours and patterns help users quickly understand what the device is doing or alert them to any issues.
