A Device model serves as a blueprint and can be configured with the following :
Every device created within the application must be based on a device model. When a device (an instance based on the model) is created, it inherits the same templates and settings.
A key benefit of this approach is the model-instance relationship, in which any modifications made to the model's configuration are automatically reflected across all devices that are based on it. This ensures consistency and ease of management across multiple devices.
Note: This model-instance approach of creating instances is available for Assets and Locations as well. Adding a Device
To add a device instance in the Zoho IoT application, you need both a device model and a device product (not required for API endpoint devices). It's important to understand device products thoroughly before you proceed to add a device instance. Example for Device model and Device instance
For example, consider an IoT network with 30 Conzerv EM6400NG energy meters. These meters are responsible for measuring datapoints such as voltage, current, power, and frequency. In the Zoho IoT applications, a model called "Energy Meter" is created, and is configured with the datapoint templates: Voltage, Current and Power.
Based on the "Energy Meter" model, 30 device instances are subsequently created, named sequentially from EM64NG 1001 through EM64NG 1030.
Now, to monitor the average current produced, a new scheduled KPI datapoint template named "Average Current" is added to the device model. Consequently, a datapoint for Average Current is automatically added across all devices, from EM64NG 1001 to EM64NG 1030. This streamlined approach ensures that all energy meter devices in the application are equipped to measure the average current without the need to manually update each device individually.
