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.
