How to Control the LED Indicator on the ZEN34 Remote Switch

The LED indicator on your device is a useful feature for displaying status updates, but sometimes, you may want more control over how it behaves. Whether you prefer a subtle glow, a specific color, or no light at all, your device offers several customization options. In this guide, we’ll walk you through the steps to turn off the LED indicator, adjust its brightness, change its color, and modify its behavior—such as keeping it on when the device is off or vice versa. By the end of this article, you’ll have full control over the LED settings to match your preferences. Let’s get started!

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 Indicator Behavior

Parameter 1: Choose if you want the LED indicator to turn on anytime a trigger is activated (normal model) or to remain always on or off.

Values: 0 – LED indicator always off; 1 – normal mode (default); 2 – LED always on in the color specified in parameter 2; 3 – LED always on in the color specified in parameter 3.

The ZEN34 provides the following options for the standard LED behavior for the device:

The LED indicator is always off: you may choose this option if you prefer to have all of your switches match at all times with no LED indicator showing regardless of the switch status.
Normal Mode: the LED indicator will flash when the upper or lower paddle is tapped: this is the most popular option, as it confirms the command has been received and sent to the corresponding device or hub.
LED is always on in the color specified in Parameter 2 (see below)
LED is always on in the color specified in Parameter 3 (see below)

LED Indicator Color

You can select the color for the LED indicator to light up when the upper paddle is pressed and when the lower paddle is pressed.

Parameter 2: Choose the color of the LED indicator to light up in normal mode when the top paddle (scene 1) is triggered.
Values: 0 – white; 1 – blue (default); 2 – green; 3 – red; 4 – magenta; 5 – yellow; 6 – cyan.

Parameter 3: Choose the color of the LED indicator to light up in normal mode when the bottom paddle (scene 2) is triggered.
Values: 0 – white (default); 1 – blue; 2 – green; 3 – red; 4 – magenta; 5 – yellow; 6 – cyan.

The ZEN34 Remote Switch offers customizable LED indicator settings, allowing you to tailor the device's visual feedback to your preferences. The LED color can be set to one of four options: white, blue, green, red, magenta, yellow, or cyan. It’s important to note that once you set the LED color, it becomes a constant behavior—meaning that whenever the indicator turns on, it will always display the chosen color.

If you select blue, the LED will always glow blue when active.
If you switch to red, it will consistently illuminate red whenever active.

For users who rely on the LED indicator as a quick status check, this ensures predictability and consistency.

Selecting the right LED color can be both a functional and aesthetic choice. Here’s how different colors can serve various purposes:

White: A neutral and modern look, ideal for minimalistic or professional environments.
Blue: A calming and commonly recognized indicator color, often used in nighttime settings.
Green: A natural and visually distinct choice, great for energy-conscious users.
Red: A strong, attention-grabbing color that may indicate urgency or importance.
Magenta: A bold and unconventional choice, ideal for creative or expressive spaces. It conveys uniqueness and innovation, standing out in design-focused environments.
Yellow: Bright and highly visible, yellow is associated with positivity and alertness. It's excellent for drawing attention without signaling urgency, perfect for friendly notifications.
Cyan: Cool and tech-savvy, cyan bridges the calm of blue with the energy of green. It appeals to modern and tech-oriented users, often seen in futuristic interfaces.

By understanding how the LED settings work and making an informed choice, you can personalize your ZEN34 Remote Switch to best suit your needs.

LED Indicator Brightness

Parameter 15: Choose the LED indicator's brightness level.

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

In addition to choosing the LED indicator color and behavior, the ZEN34 Remote Switch allows you to adjust the brightness level of the LED indicator to match your preferences and environment. Whether you prefer a bright, highly visible indicator or a more subtle glow, the switch offers three brightness settings:

Bright (100%): The LED is at full brightness, making it easily visible even in well-lit rooms. For daytime use or in well-lit areas, the bright (100%) setting ensures the LED remains clearly visible.
Medium (60%) (Default Setting): The LED emits a balanced glow that is noticeable without being overpowering. For standard household use, the medium (60%) setting provides a good balance of visibility without excessive brightness.
Low (30%): The LED is dimmed, ideal for bedrooms or low-light environments where minimal illumination is preferred. For nighttime environments, bedrooms, or light sensitive individuals, the low (30%) setting offers a soft glow that minimizes disturbance.

By fine-tuning the LED brightness level, you can enhance both functionality and comfort, ensuring the switch blends seamlessly into your living space without unnecessary distraction.

Can I Program the LED Indicator in Automations?

While you can program the LED indicators for our standard wall switches, an especially popular option for our ZEN32 and ZEN35 scene controllers, this is not the case on a remote. Since the wall switches are hardwired, they are always on and listening devices, which means you can program the LED indicator behavior in automations. The ZEN34 Remote Switch is not a device you can control, as it's a battery powered device that's asleep most of the time and is meant to send events TO the hub. Since it is battery powered, the unit is always sleeping, and as such it doesn't listen for commands from the hub like hardwired devices such as ZEN32 or standard wall switches. This is the primary difference here and this is what makes it impossible to program the LED's to light up based on Z-Wave commands.

By fine-tuning the LED behavior on your ZEN34 Remote Switch, you can enhance both functionality and comfort, ensuring the switch blends seamlessly into your living space without unnecessary distraction.
