How Can We Help?
Device Classification
Watson IoTThe Internet of Things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these objects to connect and exchange data. allows for device classification by Type, Manufacturer, Model, etc., that can be helpful in grouping similar devices and to filter/retrieve subset of devices. This classification is not available in Azure IoT.
Device Management
Devices can choose to notify the Watson IoT Platform device management server about changes to their status using Error Codes, Diagnostic Logs and Connection Logs. Azure IoT doesn’t offer this functionality.
Device Connection Status
It is not possible to get device connection status in Watson IoT on-demand. It is only available by subscribing to an MQTT channel. Whereas, Azure IoT provides connection status through an API.
Data Management using Device Twin
Device Twin functionality in Azure IoT is used to synchronize current state information between the device and IoT platform. Whereas in Watson IoT, apart from synchronization of current state information, a device twin is also used for normalizing data from devices of different makes or models that publish data in different formats. This is accomplished by defining a logical interface model and mapping with the device event properties.
Job Scheduling
In Azure IoT, it is possible to schedule device actions like reboot/reset or firmware updates at a later date. But in Watson IoT, these actions start as and when the job is initiated.
