3. Edge Xpert Device Services

Device Services are the edge connectors interacting with the devices or IoT objects that include, but are not limited to: appliances in your home, alarm systems, HVAC equipment, lighting, machines in any industry, irrigation systems, drones, traffic signals, automated transportation, and so forth.

Device services may service one or a number of devices, including sensors, actuators, and so forth, at one time. A “device” that a DS manages, could be something other than a simple single physical device and could be another gateway and all of that gateway’s devices, a device manager, or a device aggregator that acts as a device, or collection of devices, to EdgeX Foundry.

The Device Services layer’s microservices communicate with the devices, sensors, actuators, and other IoT objects through protocols native to the IoT object. The DS Layer converts the data produced and communicated by the IoT object, into a common EdgeX Foundry data structure, and sends that converted data into the Core Services layer, and to other microservices in other layers of EdgeX.

Edge Xpert currently support the following devices services:
