Brain Fleet
From one cabinet to a fleet across multiple sites. Brain Fleet coordinates them with one dashboard.
Subscription required
Fleet management features require a Brain Cloud subscription (€49 / cabinet / month). Single-cabinet operation, local MQTT, and direct cabinet access work standalone without subscription. See /pricing.
Air-gapped • EU AI Act-aligned • Five-tier safety authorization • Full audit trail
Zero Config
Every Brain cabinet publishes an MQTT heartbeat every 30 seconds. The fleet dashboard auto-discovers new cabinets, tracks their health, firmware version, I/O usage, and uptime. No manual provisioning. No discovery phase. No setup wizard.
Cabinets and Gateways
Brain Fleet manages all device types: Brain Core cabinets, Brain Pro cabinets, and Brain Gateway protocol bridges. One dashboard, mixed deployments.

Concept design — production fleet dashboard ships with Brain Cloud Q3 2026.
Roles & Access
Vienna plant operators see only Vienna cabinets. Graz line A maintenance sees only Graz line A. Plant directors see all sites. RBAC scoped to cabinet, site, and role. JWT-based, audit-trailed, revocable.
Cross-Device
Publish tags from cabinet A. Subscribe from cabinet B. Coordinate production across cabinets without a central SCADA. Each cabinet is peer-to-peer.
Cabinet A finishes stage 1, publishes LINE.STAGE1.COMPLETE — Cabinet B picks it up and starts stage 2.
Cabinet A publishes CAPACITY.AVAILABLE — Cabinet B routes overflow automatically.
Cabinet A misses heartbeats, Cabinet B raises an alarm and can take over pre-configured tasks.
Fleet AI
Brain AI on the fleet dashboard queries every cabinet at once. “Which cabinets had alarms in the last 24 hours?” “Which cabinet is running the highest energy use this week?” “Compare PID loop performance across all bottling lines.” Brain Fleet AI uses MCP to aggregate across cabinets and answer fleet-level questions natively.
Per-cabinet vs Fleet
| Action | Single cabinet | Fleet dashboard |
|---|---|---|
| View status, alarms | ✓ | ✓ across all |
| Edit programs, HMI | ✓ | ✗ — cabinet-local |
| Approve AI actions | ✓ | ✗ — cabinet-local |
| Push firmware updates | ✓ | ✓ staged rollout |
| Compare KPIs | ✗ | ✓ across cabinets |
| Cross-cabinet coordination | ✗ | ✓ pub/sub tags |
Firmware Over The Air
Stage, canary, and production phases with automatic rollback on failure. WPB412 bootloader on every I/O board accepts firmware updates over RS-485. Brain OS updates via standard APT/OTA.
Field updates without JTAG
Field firmware updates without JTAG, USB, or physical access. The WPB412 bootloader on every I/O board accepts signed updates over RS-485 from the Brain OS dashboard.
01
Stage on test cabinets first.
02
Canary on a configurable subset — monitor before going wider.
03
Roll to production with auto-rollback on failure.
Fleet Security
mTLS between cabinets and fleet dashboard. HMAC-signed webhooks. JWT for operator sessions. ATSHA204A hardware auth on every I/O board. Zero trust from the silicon up.
mTLS
Every cabinet-to-fleet connection uses mutual TLS with cert-based auth.
HMAC Webhooks
Every outbound webhook signed with per-cabinet secret. Replay-resistant.
JWT Sessions
Operator sessions scoped to cabinet + role. Short-lived, refreshable.
ATSHA204A
Hardware auth chip on every I/O board. Counterfeit-resistant.
Cloud
Brain Cloud subscription, hosted fleet dashboard, accessible from anywhere.
On-premise
Self-hosted fleet dashboard on your infrastructure. No cloud dependency. Included with Brain Compliance subscription. See /local-ai for sovereignty levels.
Every cabinet runs independently if the fleet dashboard goes down — see /reliability for degraded-mode behavior.
Example deployment cost
Hardware (one-time)
10× Brain Pro = €50,000
Subscription (recurring)
10× Brain Cloud = €490 / month
€5,880 / year recurring
Compares favorably to Siemens Industrial IoT subscription pricing — and helps procurement teams build the case internally.
