How to Control the LED Indicator on the ZEN77 Dimmer

The LED indicator on your ZEN77 Dimmer provides helpful visual signals, but you may prefer more control over its functionality. Whether you want a dimmer light, a different hue, or to turn it off completely, the ZEN77 offers various customization features to match your preferences.

In this guide, we’ll walk you through adjusting the LED indicator—disabling it, modifying brightness, choosing a new color, and changing its activation settings. Whether you prefer the light to be on when the switch is off or vice versa, you’ll learn how to set it up just the way you like.

Let’s dive in!

Understanding Advanced Settings

The naming of advanced settings depends on your Z-Wave hub. For example, Hubitat categorizes them under “Preferences,” SmartThings labels them as “Settings,” while Home Assistant and HomeSeer refer to them as “Parameters.” Despite the different terms, they all serve the same function—configuring your device’s behavior. A complete list of available settings for each device can be found in our Knowledge Base.

Each advanced setting consists of four main components:

Label: If your device integrates properly with your hub, this will display as the setting’s name. Platforms like SmartThings will show just the label and description without the parameter number.
Parameter Number & Description: Hubs such as Hubitat and Home Assistant display the parameter number along with its label and details.
Values: These represent the available options for each setting, ranging from simple (e.g., Enable/Disable) to numeric values.
Size: Some platforms require this when manually configuring settings (e.g., Home Assistant) or when hubs don’t provide direct access to modifications.

Keep in mind that not all hubs grant access to advanced settings. For example, security systems like Alarm.com and Ring may recognize the device and support integration but don’t allow configuration changes.

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 ZEN77 Dimmer offers several options to personalize its LED indicator, allowing you to tailor its behavior to suit your needs:

LED on when the switch is off – Ideal for nighttime visibility, this setting keeps the LED illuminated when the lights are off, helping you locate the switch in the dark.
LED on when the switch is on – Perfect if you want the LED to reflect the light’s status, lighting up only when the connected fixture is turned on.
LED always off – For a sleek and minimalistic appearance, this setting disables the LED completely, keeping it off at all times.
LED always on – A useful option if you prefer the LED to stay visible in dim environments or as a constant indicator that the switch is powered and operational.

You can easily switch between these LED settings using manual paddle presses directly on the device. By default, the LED is set to turn on when the switch is off. To change this setting:

Tap the upper paddle six times in rapid succession to move to the next available LED mode.
Repeat the process if you’d like to continue cycling through the settings until you reach your desired option.

This quick adjustment method allows you to modify the LED indicator without relying on a smart hub or app, making customization simple and hassle-free. You can find a complete list of settings, including the default values, in our advanced settings guide for each device.

LED Indicator Color

Parameter 23: Choose the color of the LED indicator.

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

The ZEN77 Dimmer lets you personalize the LED indicator settings, giving you full control over how it provides visual feedback. With four color options—white, blue, green, or red—you can match the LED to your décor or use it for a functional purpose.

The LED serves as a quick reference for the switch’s status, adapting to your chosen settings. Whether it signals when the switch is on, off, or in a specific mode, the selected color remains consistent whenever the indicator is active.

Setting the LED to blue ensures it always glows blue when in use.
Choosing red means the LED will consistently light up red whenever active.

This consistency makes the LED a dependable visual cue, helping users easily identify the switch’s status at a glance.

Choosing the Right LED Color

The color you choose can enhance both the functionality and style of your switch:

White – A clean, modern look that blends seamlessly into contemporary or professional spaces.
Blue – A soothing, easy-to-spot color, ideal for nighttime visibility without being too harsh.
Green – A vibrant, energy-conscious choice, perfect for indicating eco-friendly or low-power usage.
Red – A strong, attention-grabbing color that can serve as a warning, reminder, or status indicator.

By customizing your ZEN77's LED settings, you can tailor its appearance and function to suit your home’s design and your specific needs.

LED Indicator Brightness

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

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

In addition to adjusting the LED color and behavior, the ZEN77 allows you to fine-tune the LED indicator’s brightness to match your environment and preferences. Whether you prefer a bright, easy-to-see light or a more subtle glow, you can select from three different brightness levels:

High (100%) – The LED glows at full brightness, ensuring clear visibility even in bright rooms or during the day. This setting is ideal for high-traffic areas, offices, or places where a strong visual cue is needed.
Medium (60%) (Default Setting) – A well-balanced brightness level that is noticeable without being overpowering. This option works well for most household settings, offering clear visibility without excessive glare.
Low (30%) – A softer glow designed for bedrooms, nurseries, or nighttime use, reducing glare and minimizing light distractions while still providing a subtle visual reference.

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 ZEN77 Dimmer includes an LED confirmation feature that briefly flashes the indicator whenever you adjust a setting or parameter. This visual cue provides instant feedback, confirming that your changes have been successfully applied. However, you can turn this feature on or off based on your preferences.

When to Keep LED Flashing Enabled:

Instant Confirmation – Ensures you immediately see when a setting has been updated.
Easier Troubleshooting – Helps verify changes, such as LED color or brightness, without guessing.

When to Disable LED Flashing:

For Smart Home Automations – Prevents unexpected flashes that might interfere with automated routines.
For a Seamless Look – Maintains a steady LED appearance without brief interruptions.

By customizing this setting, you can fine-tune the ZEN77’s LED behavior to better align with your home’s aesthetics and automation setup.
