I discovered a Multiple Profile issue and resolution. Essentially Amazon Profiles are devices specific. Smart home device Conflicts will arize if the devices are registered on more then one Amazon Profile.
Steps to duplicate:
In order to solve this conflict you have 2 options;
I see why Alexa cannot support multiple profiles. Duplication or any profile data will cause a conflict. For example, if one mobile number is registered to an account it cannot be used to set up calls on another Alexa device.
I searched for "discovery failed" issues and resolutions and never found a reference to profile conflicts. Perhaps the Alexa developers can validate my observations and proposed resolution. I almost returned my Alexa device and smarthome devices because of this issue. I cant be the only one that has come accross this issue. Maybe the answer is published but I couldn't find it. I suggest that in the next code release for your API you provide a better error message that gives more information about the issue or if just add a number if there are multiple error codes so someone call look up the error code.
