Fleets and devices

Fleets and devices are the core operational objects in Golain. Everything else — Edge Sync, telemetry, SSH — attaches to a device inside a fleet within a project.

Fleets

Create a fleet

Open your project → Fleets → Create fleet.
Provide a name and optional description.
Save.

Fleets are unique by name within a project. You can also create fleets via CLI:

platform-tui fleets create --name=warehouse-sensors --description="Floor 2 BLE gateways"

List and delete

Console: fleet list shows device counts and metadata.
CLI: platform-tui fleets list · delete with platform-tui fleets delete <name-or-id> --yes

Devices

Register a device

Open a fleet → Devices → Add device.
Set name and type (typically mqtt).
Save and open the device detail page.

CLI equivalent:

platform-tui devices create --name=sensor-01 --fleet=warehouse-sensors --type=mqtt

Device detail

The detail view shows:

Section	Contents
Status	Connected / offline / never connected, last seen
Identity	Device ID (UUID), name, fleet
MQTT	Broker host, port, TLS, client ID, topic filters
Tags	Labels for targeting and filters
Certificates	mTLS material when cert-based auth is enabled

Copy MQTT settings when configuring Omega or third-party MQTT clients. CLI:

platform-tui devices get sensor-01 --fleet=warehouse-sensors
platform-tui devices mqtt-details sensor-01 --fleet=warehouse-sensors --output=json

Delete a device

Removing a device revokes its MQTT credentials and frees the name within the fleet. Confirm in UI or use:

platform-tui devices delete sensor-01 --fleet=warehouse-sensors --yes

Monitoring connectivity

Fleet view — aggregate online/offline counts.
Event stream — live connect/disconnect and MQTT access events.
platform-tui TUI — Stats & graphs screen shows Unicode gauge bars for fleet connectivity.

platform-tui events watch --device=<uuid>
platform-tui events list --source=mqtt --limit=50

Edge enrollment

For Golain-managed certificate enrollment instead of manually copying MQTT passwords, configure Omega JITR with org, project, fleet, and device identity matching the console registration.

Next steps

Edge Sync — configure SQLite replication and download Omega bundles
Edge connect — bring devices online with Omega
