12. Settings & Tools

The Settings & Tools section in SLZB-OS contains core configuration and maintenance options that apply to the entire coordinator, regardless of the selected Zigbee mode or network configuration.

12.1 General Settings

12.1.1 Device Name

• Sets a friendly name for your coordinator.

• Appears in the web interface header and can help distinguish multiple devices.

12.1.2 Update Check Interval

• Defines how often SLZB-OS checks for firmware updates (in hours).

• Minimum: 1 hour; Maximum: 168 hours (1 week).

12.1.3 Enable Remote Support Mode

• Allows temporary remote access by SMLIGHT support (if instructed).

• For troubleshooting purposes only.

12.2 Firmware Update

The Firmware Update page allows upgrading SLZB-OS to the latest release or a specific version.

12.2.1 Update Methods

1. Online Update

   • Fetches and installs the latest stable firmware from SMLIGHT servers.

2. Manual Upload

   • Lets you upload a .bin firmware file from your computer.

12.2.2 Update Process

1. Select update method (online or manual).

2. Confirm and start update.

3. Device will reboot automatically after installation.

Note: Updating SLZB-OS does not affect your Zigbee network data — Zigbee pairing and configuration are stored in Zigbee2MQTT/ZHA, not in the core firmware.

12.2.3 Automatic Zigbee Firmware Updates

• Enable Zigbee Automatic Updates (checkbox):

  • When enabled, SLZB-OS will automatically check for Zigbee firmware updates every # DAY and TIME (for example, every fifth day at 3 am)

  • If a new version is found, the Zigbee chip will update automatically.

  • This process restarts the Zigbee component — ensure your Zigbee2MQTT or ZHA setup is ready to reconnect devices after the restart.

12.3 LED Settings

This page configures the behavior of the onboard status LEDs.

12.3.1 LED Modes

• Always On – LEDs remain lit continuously.

• Always Off – LEDs are disabled entirely.

• Status Indication – LEDs display network or coordinator activity.

• Blink on Activity – LEDs flash when Zigbee or network events occur.

• Adjusts LED brightness (0–100%).

12.4 Time Settings

12.4.1 Time Zone

• Select the time zone for the coordinator’s internal clock.

12.4.2 NTP Server
