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.
