Returns complete topology structure and real-time thing model status of currently online and offline-pending devices in project. ### Topology Structure Each topology record is grouped by device role:

• host — Center node (usually aircraft); null if topology has no aircraft
• parents — Gateway nodes (Remote Controller, Dock, Base Station)
• nodes — Child nodes (Relay devices, etc.) ### Thing Model Data Each device node's device_state contains the device's real-time thing model attributes. Structure determined by device_model.key (format {domain}-{type}-{sub_type}); different models return different attribute sets. device_state is null when device is offline. ### Filter Rules Server automatically filters following devices, not returned in results:

1. Topologies with only remote controllers and no aircraft
2. Non-dock/non-aircraft/non-relay/non-base-station devices completely offline for more than 5 minutes
3. Offline aircraft whose topology does not contain dock or base station ### Call Conditions Caller must be member of the project.
