I have installed the Echo Speaks Smart App in the SmartThings app. When I go to Smart Apps, Echo Speaks is there. When I start Echo Speaks, it tells me that there are no Alexa Devices installed. It also states Login Status (invalid). It appears that I am not logged into Amazon. When I tap Alexa Login Status|Service Management, it gives me Manage Login Service and two choices: Heroku (Configured) and Domain (amazon.com). Note that Heroku server has been deployed.
I am not certain what I am doing wrong and why Echo Speaks will not recognize the Echo Dot (or any other Alexa devices) as discoverable. Any help would be appreciated. Thanks.
