Credentials (.bmus_credentials)

Updated on 01.01.2026

The hidden file .bmus_credentials contains the credentials to the MySQL database and the NAS or the backup destination and the WebDAV port on the NAS.

Mac/Finder: To show hidden files in Finder, press the Command + Shift + dot (.) keys together in Finder. All hidden files and folders will then become visible. To hide them again, press the same key combination again.

Windows: Open File Explorer (Windows + E keyboard shortcut).

Click the View tab in the top bar. In the “View” section, click the “Hidden files” box or check the “Show hidden files” box. 

Linux/Raspberry etc.: Open the terminal. Navigate to the desired directory using cd if necessary. Type ls -a and press Enter. The -a option stands for “all” and also shows hidden files (starting with a dot).

NAS credentials

NAS_USER="YourNasUser"
NAS_PASS="YourNasPassword"

MySQL access data (only necessary for BACKUP_SQL=1)

MYSQL_USER="user"
MYSQL_PASS="YourMySQLPassword"

Pi user (Normal version)

PI_USER="user"

Pi user (Docker version)

PI_USER="root" # do not change. Must be root, because we map to root!

WebDAV-Port (optional, for dashboard link in mail)

If configured, the report will be sent by email. If dashboard generation is active, the dashboard will be sent as an attachment with the email. To view the dashboard, click on it and it will be displayed by the browser.

This is what the report mail looks like:

However, depending on the email client and operating system, a more rudimentary web browser may be loaded. Many of these browsers do not interpret JavaScript well (or at all). In this case, the dashboard graphs will not load.

If this happens, you must save the dashboard from your mail to your hard drive and open it in your browser. This is not only very inconvenient, but also does not work very well on mobile phones.

The solution is to configure a WebDav server on the NAS (or backup destination) where BmuS stores the dashboard. If the WebDav-Port is configured here, BmuS inserts a link to the WebDav server and you can access the dashboard very conveniently.

WEBDAV_PORT="5001" # Leave blank if no WebDAV.
