The alexa skill is called 'Simple Commands' and works directly with your items to allow voice control over your items. This includes Groups and Routine as well as individual items.
Unlike other skills the 'Simple Commands' Skill absorbs your natural language request and takes action on your item. There is no need to have alexa discover your device nor is there a need for any special configuration on the SimpleCommands app to support this natural language request format.
Step 1: Go to the alexa app or alexa.amazon.com and select 'Skills' or 'Skills and Games'
Step 2: Search for the Simple Commands skill or follow this link to be taken directly to the Skill
Step 3: Select 'Enable Skill' at the top of the page
Step 4: After Page refreshes select 'Settings' at the top of the page
Step 5: After Page refreshes select 'Link Account' at the top of the page
Step 6: If you are not already logged into SimpleCommands you will be prompted to re-enter your SimeplCommands username/email and password
Thanks it for enabling the alexa account. Unlike the home skills you do not need to discover devices or make any other changes in the alexa app.
Now you are ready to go!
Things you can ask alexa: ( examples assume item names of 'Right Door' and 'Ring Alarm' )
