Here is the quick tutorial:
1. Install Blynk app on your phone (find Blynk in your app store and install it).
2. Run Blynk app, in Blynk can find a QR code scan button, click it and then scan the QR code that’s in the user manual:
3. Once the project is scanned, go to the Project Settings, copy or email the Blynk token to yourself. This is the token you need to put into the webpage Settings.
4. Restart OpenGarage and it should now communicate with Blynk. Make sure the Blynk project is running (in the project there is a triangle-shaped Run button).
