Use workflows to integrate your Azure IoT Central application with other cloud services
You can create rules in IoT Central that trigger actions in response to telemetry-based conditions. For example, to send an email when a device temperature exceeds a threshold.
The Azure IoT Central V3 connector for Power Automate and Azure Logic Apps lets you create more advanced rules to automate operations in IoT Central:
- When a rule fires in your Azure IoT Central app, it can trigger a workflow in Power Automate or Azure Logic Apps. These workflows can run actions in other cloud services, such as Microsoft 365 or a third-party service.
- An event in another cloud service, such as Microsoft 365, can trigger a workflow in Power Automate or Azure Logic Apps. These workflows can run actions or retrieve data from your IoT Central application.
- Azure IoT Central V3 connector aligns with the generally available 1.0 REST API surface. All of the connector actions support the DTDL v2 format. For the latest information and details of recent updates, see the Release notes for the current connector version.
Prerequisites
To complete the steps in this how-to guide, you need:
An active Azure subscription. If you don't have an Azure subscription, create a free account before you begin.
An IoT Central application created from the Custom application template. To learn more, see Create an IoT Central application and About your application.
Trigger a workflow from a rule
Before you can trigger a workflow in Power Automate or Azure Logic Apps, you need a rule in your IoT Central application. To learn more, see Configure rules and actions in Azure IoT Central.
To add the Azure IoT Central V3 connector as a trigger in Power Automate:
- In Power Automate, select + Create, select the Custom tab.
- Search for IoT Central, and select the Azure IoT Central V3 connector.
- In the list of triggers, select When a rule is fired (preview).
- In the When a rule is fired step, select your IoT Central application and the rule you're using.
To add the Azure IoT Central V3 connector as a trigger in Azure Logic Apps:
Important
Triggers in the IoT Central connector won't work unless the Logic App has a public endpoint. To learn more, see Considerations for inbound traffic to Logic Apps through private endpoints.
- In Logic Apps Designer, select the Blank Logic App template.
- In the designer, search for IoT Central, and select the Azure IoT Central V3 connector.
- In the list of triggers, select When a rule is fired (preview).
- In the When a rule is fired step, select your IoT Central application and the rule you're using.
You can now add more steps to your workflow to build out your integration scenario.
Run an action
You can run actions in an IoT Central application from Power Automate and Azure Logic Apps workflows. First, create your workflow and use a connector to define a trigger to start the workflow. Then use the Azure IoT Central V3 connector as an action.
To add the Azure IoT Central V3 connector as an action in Power Automate:
- In Power Automate in the Choose an action panel, select the Custom tab.
- Search for IoT Central and select the Azure IoT Central V3 connector.
- In the list of actions, select the IoT Central action you want to use.
- In the action step, complete the configuration for the action you chose. Then select Save.
To add the Azure IoT Central V3- preview connector as an action in Azure Logic Apps:
- In Logic Apps Designer, in the Choose an action panel, select the Custom tab.
- Search for IoT Central, and select the Azure IoT Central V3 connector.
- In the list of actions, select the IoT Central action you want to use.
- In the action step, complete the configuration for the action you chose. Then select Save.
