This plugin allows some Indigo devices to be controlled via any Amazon Alexa device (Echo, FireTV, etc). Click the More Information link above for details.
First, download the latest version from the Github repo onto your Indigo Server Mac. Unzip (if necessary) and then double-click it in the Finder. The Indigo Mac client will come up asking if you want to install and enable it - do that. The config dialog will show up with debug checkboxes - just close that without changing anything at the moment.
