| This is a very basic Alexa skill to get the latest stats from a Solis Cloud Scraper installation. | |
| To configure you need to: | |
| * Add the URL of your Solis Scraper installation in the GetRemoteDataHandler function directly below | |
| * Add your Solis Scraper username and password to the getRemoteData function at the bottom | |
| I used one of the example project templates and modified it. You will have to separately choose an invocation name. | |
| You do no need to distribute this to use it, just move it to testing and it will be available to any Alexa device you are signed in to (assuming you sign in to your Amazon Developer account with the same account) | |
