Automated Zigbee Backup Upload with n8n

This workflow automates the process of backing up Zigbee network data on a weekly schedule. It first triggers every Monday at 2:45 AM and sends a backup request via MQTT to the Zigbee2MQTT bridge. When a response is received on the designated MQTT topic, the workflow parses the JSON message containing the backup data. The data, encoded in Base64, is then converted into a binary file format suitable for upload. Finally, the binary backup file is securely uploaded to an SFTP server for safekeeping. This automation ensures consistent and hands-free backups of Zigbee network configurations, minimizing data loss and simplifying maintenance.
