Sample Flows

Sample flows for enebular-edge-agent there are.

These flows are desined for RAVEN.
If you use other kind of IoT devices, you can easy to make it applicable by changing node settings for your device.

This section is for advanced learners, since you will use sensors, actuators and extarnal web services on the market. Before your challenging, we reccomend you try enebular's GettingStarted and enebular-edge-agent's GettingStarted.

Switch cotrolling LED Flow

You can control the USER LED by pressing USER SW. The USER SW functions as a toggle switch, pressing the USER SW switches the USER LED lights on or off.

Flow to operate LEDs remotely from browser

SampleFlows-cloudLchika-image

Building an app on heroku that manages the device. The flow changes the state of the LED through the browser.

heroku's parameters are editable from browsers.

Flow on heroku

Using an app that connects to the device.

https://[your-heroku-app].herokuapp.com/set_value?v=[value] You can pass the value controlling the device by accessing it from the browser.

[your-heroku-app] contains the ID of the deployed heroku app. You can check it on heroku screen or enebular deployment screen.

After importing the JSON data, open the http request node and rewrite it to the ID of the created heroku app.

SampleFlows-cloudLchika-deviceHttp

After deploying to the device, accessiing https://[your-heroku-app].herokuapp.com/set_value?V=true from the browser will light up the LED. Accessing https://[your-heroku-app].herokuapp.com/set_value?V=false from the browser switches the LED off.
