IoT remote monitoring and notifications with Azure Logic Apps connecting your IoT hub and mailbox

[!INCLUDE iot-hub-get-started-note]

Azure Logic Apps provides a way to automate processes as a series of steps. A logic app can connect across various services and protocols. It begins with a trigger such as 'When an account is added', and followed by a combination of actions, one like 'sending a push notification'. This feature makes Logic Apps a perfect IoT solution for IoT monitoring, such as staying alert for anomalies, among other usage scenarios.

What you learn

You learn how to create a logic app that connects your IoT hub and your mailbox for temperature monitoring and notifications. When the temperature is above 30 C, the client application marks temperatureAlert = "true" in the message it sends to your IoT hub. The message triggers the logic app to send you an email notification.

What you do

• Create a service bus namespace and add a queue to it.
• Add an endpoint and a routing rule to your IoT hub.
• Create, configure, and test a logic app.

What you need

• Tutorial Setup your device completed which covers the following requirements:
  • An active Azure subscription.
  • An Azure IoT hub under your subscription.
  • A client application that sends messages to your Azure IoT hub.

Create service bus namespace and add a queue to it

Create a service bus namespace

1. On the Azure portal, click Create a resource > Enterprise Integration > Service Bus.

2. Provide the following information:

   Name: The name of the service bus.

   Pricing tier: Click Basic > Select. The Basic tier is sufficient for this tutorial.

   Resource group: Use the same resource group that your IoT hub uses.

   Location: Use the same location that your IoT hub uses.

3. Click Create.

   

Add a service bus queue

1. Open the service bus namespace, and then click + Queue.

2. Enter a name for the queue and then click Create.

3. Open the service bus queue, and then click Shared access policies > + Add.

4. Enter a name for the policy, check Manage, and then click Create.

   

Add an endpoint and a routing rule to your IoT hub

Add an endpoint

1. Open your IoT hub, click Endpoints > + Add.

2. Enter the following information:

   Name: The name of the endpoint.

   Endpoint type: Select Service Bus Queue.

   Service Bus namespace: Select the namespace you created.

   Service Bus queue: Select the queue you created.

3. Click OK.

   

Add a routing rule

1. In your IoT hub, click Routes > + Add.

2. Enter the following information:

   Name: The name of the routing rule.

   Data source: Select DeviceMessages.

   Endpoint: Select the endpoint you created.

   Query string: Enter temperatureAlert = "true".

3. Click Save.

   

Create and configure a logic app

Create a logic app

1. In the Azure portal, click Create a resource > Enterprise Integration > Logic App.

2. Enter the following information:

   Name: The name of the logic app.

   Resource group: Use the same resource group that your IoT hub uses.

   Location: Use the same location that your IoT hub uses.

3. Click Create.

Configure the logic app

1. Open the logic app that opens into the Logic Apps Designer.

2. In the Logic Apps Designer, click Blank Logic App.

   

3. Click Service Bus.

   

4. Click Service Bus – When one or more messages arrive in a queue (auto-complete).

5. Create a service bus connection.

   1. Enter a connection name.

   2. Click the service bus namespace > the service bus policy > Create.

      

   3. Click Continue after the service bus connection is created.

   4. Select the queue that you created and enter 175 for Maximum message count

      

   5. Click "Save" button to save the changes.

6. Create an SMTP service connection.

   1. Click New step > Add an action.

   2. Type SMTP, click the SMTP service in the search result, and then click SMTP - Send Email.

      

   3. Enter the SMTP information of your mailbox, and then click Create.

      

      Get the SMTP information for Hotmail/Outlook.com, Gmail, and Yahoo Mail.

   4. Enter your email address for From and To, and High temperature detected for Subject and Body.

   5. Click Save.

The logic app is in working order when you save it.

Test the logic app

1. Start the client application that you deploy to your device in Connect ESP8266 to Azure IoT Hub.

2. Increase the environment temperature around the SensorTag to be above 30 C. For example, light a candle around your SensorTag.

3. You should receive an email notification sent by the logic app.

   [!NOTE] Your email service provider may need to verify the sender identity to make sure it is you who sends the email.

Next steps

You have successfully created a logic app that connects your IoT hub and your mailbox for temperature monitoring and notifications.
