PWA prototype

BB-Tank Dashboard

Remote dashboard

One dashboard for tanks now, delegated access later.

The prototype uses the BB-Tank /api/tank/ui-state and /api/tank/ui-config contract, and adds a device-scoped warm-up flow that returns a cached PWA association and WSS relay bundle from the device.

The device pre-warms relay credentials first, then the PWA association if needed.

Transport and raw state

Useful while the device bridge and WSS relay flow are being wired up.

Connection model

The prototype prefers SSE, falls back to polling, and keeps the device bridge visible for provisioning only.

  • State/api/tank/ui-state

Remote provisioning

Device association bridge

The device pre-warms its provisioning record on STA/IP, stores it in NVS, and relays the cached WSS bundle back to the PWA.

Provisioning state Idle

Status No association loaded
Requested scopes

    The PWA only receives the device-scoped WSS bundle; it does not choose the provisioning server.

    No remote association loaded.
