Why Activation Is Required

HelmOS will start its HTTP and WebSocket services without a license but refuses to fire cues, accept deploys, or push OTA updates. The Cuemaster dashboard shows a full-screen activation overlay until a valid token is applied.

Procedure

  • Open Cuemaster at http://<helm-ip>:3000/. The activation overlay appears.
  • Read the device fingerprint (16 hex characters formatted XXXX-XXXX-XXXX-XXXX).
  • Submit the fingerprint plus your customer information to your Northstar reseller.
  • Receive a license token beginning with NSSS1.
  • Paste the token into the textarea and click Activate.
  • On success the overlay clears and the dashboard becomes live.

What's in the Token

  • Format version
  • Issuer (always NSSS)
  • Product key (compose, helmos, or northstar)
  • Device fingerprint binding
  • Customer name
  • Issued and optional expiry timestamps
  • Ed25519 signature

Common Activation Errors

ErrorCause
Signature invalidToken was modified or copied incorrectly
Device fingerprint mismatchToken was issued for a different machine
Product mismatchToken is restricted to Compose-only (prod compose); reissue with prod helmos or northstar
ExpiredToken's expires field is in the past
Token must start with NSSS1.Wrong format — check for leading whitespace or wrong line copied

Re-activation

A license remains in effect until explicitly deactivated or until the expiry date passes. If you migrate HelmOS to new hardware, the device fingerprint changes and a new token is required.
