Manager Application

The Manager application builds the Ioto Device Manager for cloud-based device management.


The Manager application is used by EmbedThis to create the standard Device Manager application. However, you can also use it as a basis for creating your own bespoke cloud-based management application.

The manager application includes core functionality useful for most cloud-based management apps by offering:

  • User authentication (login/logout)
  • User account registration (email verification, forgot password support)
  • App navigation and menus
  • Sidebar navigation
  • Display light / dark mode support
  • Dashboards with information widgets (graphs, gauges, tables, numerics)
  • Device data display, management and updating
  • Device claiming and registration


To build the manager application select the APP and run make:

$ make APP=manager clean build

The build will achieve the following goals:

  • Build the Ioto agent with required services for cloud-based management
  • Build the manager application
  • Copy the required configuration to the ./config directory

After building, the Ioto agent binary will be located in the build/PROFILE/bin/ioto file. The standard manager application will be located under the apps/manager/ui/dist directory which will contain the individual application files and a ZIP file that is ready for uploading via the Builder to the Ioto cloud service for hosting the UI.


To deploy the manager application, logon to the Builder site to create and configure a Device Manager.

From the Builder manager list, click on the Add Manager" icon or the Edit** icon to modify a Device Manager.

Manager Domain Name

Device Managers are hosted by Embedthis on a sub-domain of your choosing under the domain. You can select a unique sub-domain that reflects your company or product's brand. The sub-domain name you choose must be globally unique. Alternatively, you can register your own domain name and point that to the underlying Ioto manager site.

To use an Ioto sub-domain, enter the sub-domain name of your choosing. To use a self-hosted domain, check the "Self Hosted Domain" checkbox and enter your full domain name. If using a self-hosted domain, you will need to use a Domain Registrar of your choosing.

App Upload

To upload the built manager, select Custom App and click on the Zip File upload field. Navigate to the apps/manager/ui/dist/ file and then Save. This will upload the manager application and deploy to the Ioto service in the appropriate cloud region. It may take a few minutes for the application to be deployed by the Ioto service.

Device Schema

The Ioto Cloud Manager uses the Ioto agent database schema to define what device specific data should be stored in the cloud and what are the device manageable entities.

The schema describes the device entities and their data properties and data types. Using this schema, the Ioto service and Manager are able to understand your device-specific data.

Ioto defines a default schema when you create the device cloud. This schema supports a generic key/value store. Initially, you can use the default schema, but as you progress, you may wish to define your own data entities to store device specific data. In this case, you will need to upload your application database schema to the Builder using the Cloud/Edit configuration panel.

For more information about the device schema, See:

Configuring the Manager Display

The Manager user interface is defined by a JSON configuration file called display.json5 that can be modified or extended to suit your specific needs.

The display.json file defines the following items:

  • Displayed Name
  • Display color theme including dark and light modes
  • Menu items and options
  • UI pages
  • Data tables and fields
  • Device data edit property panels
  • Dashboard data and widgets to display

The initial display.json5 configuration file defines a "developer" skin for the manager.

For more information about the display file, read Manager Display.
