Alexa, no cloud, external port 8123 with events!

[KeithL (Keith)]

Note, pretty sure it doesn’t matter but I’m in Canada though I choose to tell Amazon that US is my location 'cause this stuff doesn’t work using Canada. It works in other regions (Ireland etc.) but I don’t know which URLs change for other regions. Search this forum and/or Google to find out.

So as I understand, you have progressed through the HA instructions , editing the matt2005 and keeping (not deleting) the LLAT and now you are at the Linking section and need more detail on differences from the HA instructions:

At the HA instructions Linking section use only the following, slightly edited subset of this post to replace most of the Linking section.

Set Up Login With Amazon

1. Sign in to the Amazon Developer Console .
2. Click this link for “Login With Amazon ”.
3. Click the gold button that reads “Create a New Security Profile ”.

• Enter any security profile name you’d like, e.g. “HA”
• Write a short description, e.g. “Home Assistant”
• Add any url you’d like for the privacy notice, e.g. “https://myhass.example.com ”

4. Click “Save” to continue.
5. On your new Security Profile, click the gear button, and choose “Web Settings”.
6. Make note of the Client ID, and Client Secret. Keep this window open for reference.

6. In “Allowed Return URLs” section, click “Add another” until you have three lines.

Now continue the HA instructions starting at the screenshot near the end of the Linking section

A small caution. there may be minor mistakes or missing items (though I did look carefully) and there may be more questions you have. Please help others by including me in your struggles so I can edit this post to give the next person a complete and simple HOWTO. I will be happy to you and others.
