Commanding a Tesla Model S Using Amazon Echo (Video) @teslarati.com
"ask Alexa to pull the Tesla out of or into the garage "
"The tech behind this is all based in the cloud...using the Amazon Echo’s Alex Skill Kit to trigger on a keyword (‘ask KITT’) and send the resulting event to AWS Lambda. Lambda then executes... code ... Lambda function with Apex, ... use the Tesla Golang library ... The Golang code on Lambda then calls the unofficial Tesla API which in turns triggers the car to take action. In this case, to open the garage door via Homelink and drive on out using the Summon capability.
