Getting ready to do my first action on my HE. One post suggests that I go to the App section and add the Amazon Echo Skill. I also notice the option to add the Amazon Echo App. Which is the better way to go.
Skill, but install it through Amazon echo app on phone or tablet. If you go through echo, it will auto install on hub.
There are pros and cons to each.. The skill generally has more features and support.. But the app is local...
You don't install anything on HE. Go to the Alexa app on your phone and add it there and it will auto-install in HE.
But for continued support and development I would stick to the skill route
