This project automates the creation of a private Alexa Skill that enables Proactive Notificatons aka "yellow/orange ring", a feature that is not unfortunately not available via Alexa Media Player integration, because it requires the presence of a dedicated Alexa Skill and cannot be triggered just using the reversed APIs.
The alternatives I've found around were to use 3rd party skills to use as a pass-through, like Notify Me. But besides the implication of privacy, you are passing through someone else's third-party service (besides Amazon itself), it just never worked for me. I suspect because of not available in all the country's local marketplaces.
What does this ingration do?
- asks for your Amazon developer password
- It is used to create, on your behalf, a private developer skill and deploy it on your account.
- exposes a service on HA you can use to trigger notifications on Alexa, contacting that same skill
No manual interaction is required with Skill creation or configuration, other than just enabling the skill on your Alexa app on your phone and granting the notification permissions.
