2. Create a new Amazon SNS topic, e.g. autoscaling
3. Configure the Auto Scaling group to send notifications to the SNS topic created at the previous step
4. Create a new AWS Lambda function, e.g. autoscaling-2-ifttt
5. Use Node.js as runtime
6. Paste the code inline from the index.js file included in this repository
7. Replace the iftttMakerSecretKey with the one you wrote down at step 1
8. (Optional) Replace the iftttMakerBaseEventName with the one you want to use
9. Leave the default handler
10. Use a basic execution role

7. Create a Recipes
8. Choose Maker as Trigger ('this')

• the iftttMakerBaseEventName variable of the Lambda function (step 4.4 on AWS)
• the underscore character (_)
• the Auto Scaling group name
• the underscore character (_)
• the Notification type as in the table above (you can find more info on Auto Scaling notifications here)
• for exaple, if you leave the default iftttMakerBaseEventName ('autoscaling'), to monitor new instance launches on an Auto Scaling group named 'web' the Event Name to use would be autoscaling_web_EC2_INSTANCE_LAUNCH

12. Value1 contains the Auto Scaling group name
13. Value2 contains the Notification type as in the table above
14. Choose whatever you want as Action ('that'), for example:

16. A Channel from the Connected Home category to have a visible effect, e.g. Philips Hue to change the color of your lights to green when scaling up, yellow when scaling down, red in case of errors
