Device Connectivity & Management on EnOS¶
Device Connectivity & Management helps you quickly and securely connect physical devices to EnOS and start to transfer data, manage device lifecycle, and map the physical asset structure to the digital world. Device connectivity & management capabilities on EnOS include device modeling, device connectivity, device onboarding, and device management.
Device Modeling¶
Modeling in EnOS allows assets of similar characteristics to be unified into a general model to facilitate data analytics and application processing. A model is the abstraction and digitization of the physical objects, both device and logical assets, in the physical world. It describes the characteristics of the object, its capabilities, the services it can provide, and the events that may occur.
EnOS supports the reuse and standardization of models with the public model library and supports the standardization of features across models, the building of a consistent and standard data scheme, and driving the reuse of different models and applications with the standard model feature library by providing model features based on industry standards such as IEC, ICA, and OMA. Assets need to be modeled first before they can connect to EnOS.
Device Connectivity¶
The first thing to do on an IoT platform is to connect your devices to transmit data. In EnOS, there are two main methods to connect your devices, directly or through a gateway, you can choose the method based on several factors such as the device data format, the connection protocols used by the device, and the device type.
Direct Connection¶
Smart devices can connect to and communicate with EnOS directly through 3 device protocols, namely MQTT, HTTP, or CoAP, via Wi-Fi, GPRS, 3G, or 4G signals. Such devices include devices with smart acquisition rods, such as household inverters, and household energy storage batteries and smart home devices, such as surveillance cameras, and smart thermometers and hygrometers.

Connection Through Gateway¶
Another way to connect devices to EnOS is through an edge gateway device. After a device is connected to the gateway, the communication between the gateway device and EnOS will be based on the MQTT protocol. The device types that can connect to EnOS via this method include both smart devices and non-smart devices. Non-smart devices lack the ability to connect to EnOS via Wi-Fi, 3G, or 4G. Their data are first collected by the edge gateway where the gateway serves as a proxy to help the devices complete operations such as login and data transmission.

Device Onboarding¶
EnOS can pre-configure the information required to onboard devices to enable scalable and secure provisioning of devices.
Device Provisioning¶
EnOS has a helper, cloud-based service that enables zero-touch IoT device provisioning to EnOS, where millions of devices can be onboarded easily and efficiently via plug-and-play or QR code scanning.

Bulk Onboarding¶
EnOS also allows you to bulk onboarding devices with auto-logic based on business semantics. Follow the Onboarding a Solar Site and a Weather Station to EnOS to learn more.
Device Management¶
EnOS provides a full device lifecycle management as per your business needs, from the planning and design phase to the provisioning phase, servicing phase, maintenance phase, and finally the decommissioning phase. For more information, see Device Lifecycle Management.
