Use your Octoblu flows to build your own custom IoT automations. With this skill you can query your flows for any available triggers and trigger any "echo-in" node by name and then respond to the Alexa request with your custom response.
To get started you'll need a free Octoblu account. Once you've created your account, go to Bluprints -> Discover and filter for bluprints with the name "Alexa." Import any of those bluprints to create an Alexa compatible flow. You can also modify it, duplicate, or create your own Alexa flow using "echo-in" and "echo-out" nodes in the flow designer. Each "echo-in" node in a flow can only be triggered from Alexa by saying the name of the "echo-in" node.
