Note: The facility id's can be found eg. by installing Android Studio and in a Play Store enabled device emulator (indicated by the Play Icon) install the Greenely app. Run app, login with your Greenely credentials, and use Logcat in Android Studio, filtered on Greenely to find the facility ID. In the app, switch between the registered facilities to find out the different facility IDs.
