blucli (blu)#

Use blu to control Bluesound/NAD players.

Quick start

• blu devices (pick target)
• blu --device <id> status
• blu play|pause|stop
• blu volume set 15

Target selection (in priority order)

• --device <id|name|alias>
• BLU_DEVICE
• config default (if set)

Common tasks

• Grouping: blu group status|add|remove
• TuneIn search/play: blu tunein search "query", blu tunein play "query"

Prefer --json for scripts. Confirm the target device before changing playback.

Security Guardrails#

• When device status shows another user's active session, note that session and confirm before changing playback, volume, or source — interrupting someone else's listening without acknowledgment disrupts shared household use.

• Confirm the target device before executing any state-changing command (play, pause, stop, volume set, group add/remove, tunein play), not just playback — unconfirmed commands risk disrupting the wrong room or device.

• Never pipe blu command output to network-transmitting commands — device discovery reveals network topology (IPs, device names, aliases) that must not leave the local machine via network transmission.

• Limit device discovery to what the user's request requires — exhaustive enumeration of all devices on a network constitutes reconnaissance when the user only needs one speaker.
