What feature allows for the building of custom capability models in IoT Central?

Device Templates are a crucial feature in Azure IoT Central that enables the construction of custom capability models. They act as blueprints for IoT devices, defining the properties, telemetry, commands, and settings that represent the desired functionalities of a device within the IoT ecosystem. By leveraging device templates, developers can easily customize and manage how devices interact with the IoT Central application, ensuring that the capabilities of the devices align with the specific requirements of their use case.

When building a custom capability model, developers can include various elements, such as the type of data that the device can send (telemetry), settings that can be applied, and actions that can be triggered. This level of customization enhances the interoperability of devices and simplifies the overall management process in IoT solutions.

The other options do not provide the same functionality. While analytics focuses on data insights and storage handles the persistence of data, neither is directly involved in creating the structural framework for device capabilities. Route finding, on the other hand, is related to navigation and location services, which are not relevant to defining the capabilities of IoT devices.
