Digital Twin Model

Defines how devices and other entities are represented within ThingsBoard.

• Devices: Physical or virtual entity publishing telemetry or receiving commands, like Sensors or Actuators.
• Assets: Abstract entity used to group devices into logical structures: Factory Floor, Building, etc
• Relations: Connections between entities, allowing you to build parent-child hierarchies like Building (Asset) → Floor (Asset) → Thermostat (Device).
• Attributes: Entity metadata: serial number, firmware version, location, etc.
• Telemetry: Time-series data points: temperature, humidity, voltage, etc.
• Commands: Send commands from the platform back to the device and vice-versa.
