I'm logged in to SpotWalla, but the app says Invalid Device: The SpotWalla device is not enabled for web API access. Please enable the device for web access via the SpotWalla website under the devices navigation menu.
Log into spotwalla on a web browser using your account. In the upper right corner is a pull down menu with your user name. Pull down and select "Devices" This will open a page with your device(s) on the left side. Each device is also a pull-down menu. Select your device, pull down to "Web API" On this page you'll see a red box with a green button. The box will say "This device is not enabled for web. access". The button will say "Enable" Click on the Enable button.
