How to Control the LED Indicator on the ZEN72 Dimmer

The LED indicator on your ZEN72 Dimmer provides helpful visual feedback, but you may want more flexibility in how it functions. Whether you prefer a dim glow, a specific color, or no illumination at all, the ZEN72 offers multiple customization options to suit your needs.

In this guide, we’ll walk you through how to turn off the LED indicator, adjust its brightness, change the color, and modify the behavior—such as keeping it illuminated when the dimmer is off or switching it off when the dimmer is on. By the end, you’ll have complete control over the LED settings to match your personal preferences and home environment.

Let’s dive in!

All About Advanced Settings

The terminology for advanced settings varies depending on your Z-Wave hub. For instance, Hubitat lists them under the “Preferences” tab, SmartThings labels them as “Settings,” while Home Assistant and HomeSeer use the official term “Parameters.” Despite these differences in naming, the purpose remains the same: configuring consistent behavior for your device. We provide the full list of settings available for each device in our Knowledge Base.

Each advanced setting consists of four key parts:

Label: If your device is properly integrated with your hub, this will display as the setting's name. Hubs like SmartThings show only the label and description.
Parameter Number & Description: Most hubs, such as Hubitat and Home Assistant, list the parameter number along with the label and description.
Values: These are the selectable options for each setting. Some are simple (e.g., Enable/Disable), while others use numerical values.
Size: This is required in some systems when manually changing advanced settings (e.g., Home Assistant) or in hubs that do not provide direct access to settings.

It's also important to note that not all hubs allow access to advanced settings. For example, alarm panels like Alarm.com and Ring may recognize the device and offer integration but do not permit modifying its settings.

LED Behavior

Parameter 2: Choose if you want the LED indicator to turn on when the dimmer (light) is on or off, or if you want it to remain on or off at all times.

Values: 0 – LED on when switch off; 1 – LED on when switch on; 2 – LED always off; 3 – LED always on. Default: 0.

NOTE: tap the upper paddle 6 times quickly to change this mode.

The ZEN72 Dimmer offers several customizable settings for its LED indicator, allowing you to choose how it functions based on your preferences:

LED on when the switch is off – Ideal for nighttime visibility, this setting keeps the LED illuminated when the lights are off, making it easier to locate the switch in the dark.
LED on when the switch is on – A practical option for those who prefer the LED to reflect the status of the connected light, meaning the LED is only lit when the light is on.
LED always off – If you prefer a uniform look across all switches with no LED indicator visible, this setting ensures the LED remains off at all times.
LED always on – Useful for those who want the LED to remain illuminated for easy visibility in low-light conditions or as a constant indicator that the switch is powered and operational.

You can quickly cycle through these LED behavior settings using physical paddle presses on the switch itself. By default, the LED turns on when the switch is off. However, to change this:

Tap the upper paddle 6 times in quick succession to cycle to the next available setting.
Repeat the process if you want to continue cycling through the options until you reach your preferred LED behavior.

This simple method allows you to adjust the LED indicator without needing a smart hub or app, making customization quick and convenient. We list all of the options in the advanced settings article for each device, including the standard default value.

LED Indicator Color

Parameter 23: Choose the color of the LED indicator.

Values: 0 – white; 1 – blue; 2 – green; 3 – red. Default: 1.

The ZEN72 Dimmer allows you to customize its LED indicator settings, giving you control over the device's visual feedback. You can choose from four LED colors: white, blue, green, or red, allowing the indicator to blend with your décor or serve a functional purpose.

The LED light provides a quick and easy way to determine the switch’s status based on your selected settings. Whether the LED is used to indicate when the switch is on, off, or in a specific mode, the chosen color remains consistent whenever the indicator is active.

Selecting blue ensures the LED always glows blue when in use.
Choosing red means the LED will consistently illuminate red whenever active.
This consistency makes the LED indicator a reliable and predictable status tool for users who depend on visual cues.

Choosing the Right LED Color

The color you select can serve both a functional and aesthetic purpose:

White – A neutral, modern option suitable for professional or minimalistic spaces.
Blue – A calming, familiar color often used for nighttime visibility.
Green – A distinct and eco-friendly choice, great for energy-conscious users.
Red – A bold, attention-grabbing color that may signal urgency or importance.

By adjusting your ZEN72 Dimmer's LED settings, you can personalize the device to match your home environment and preferences while ensuring it serves a practical purpose.

LED Indicator Brightness

Parameter 24: Choose the LED indicator's brightness level.

Values: 0 – bright (100%); 1 – medium (60%); 2 – low (30%). Default: 1.

Beyond customizing the LED color and behavior, the ZEN72 Dimmer also lets you control the brightness level of the LED indicator to suit your preferences and surroundings. Whether you need a highly visible indicator or a softer glow, you can choose from three brightness settings:

Bright (100%) – The LED shines at full intensity, making it easily noticeable even in well-lit areas. This setting is ideal for daytime use or spaces where clear visibility is essential.
Medium (60%) (Default Setting) – Provides a balanced level of brightness that is visible yet not overpowering, making it well-suited for everyday household use.
Low (30%) – A dimmed setting designed for bedrooms, nighttime environments, or for those who prefer minimal illumination. This option reduces glare and prevents unnecessary light disturbances.

By adjusting the LED brightness, you can enhance both functionality and comfort, ensuring that the dimmer integrates seamlessly into your home without unwanted distractions.

Disable LED Indicator Flash On Setting Change

Parameter 32: Enable / disable LED indicator for setting changes. Choose if you want the LED indicators to flash whenever a parameter (settings) is adjusted on the device to confirm the change. Disable this feature if you're using the LED indicators in automations.

Values: 0 – LED indicator flashes to confirm a setting change; 1 – LED indicator doesn't flash if a setting is changed. Default: 0.

The ZEN72 Dimmer features an LED confirmation setting that briefly flashes the LED indicator whenever a setting or parameter is adjusted. This visual cue helps verify that changes have been successfully applied. However, you can enable or disable this feature based on your preferences and needs.

When to Enable LED Flashing

Instant Feedback – If you want immediate confirmation that a setting has been updated, keeping LED flashing enabled ensures each adjustment is acknowledged.
Simplified Troubleshooting – Flashing can help confirm that changes, such as LED color or brightness, have been successfully applied.

When to Disable LED Flashing

For Automations – If the LED is integrated into smart home automations, unexpected flashes could interfere with its intended function.
For a Consistent Look – Disabling LED flashing prevents momentary interruptions, ensuring a steady, uninterrupted indicator appearance.

By adjusting this setting, you can fine-tune the ZEN72's LED behavior to seamlessly fit your smart home setup.
