8. Alexa integration - Githubissues

Retry 11 Feb 2024 tawfik.daim@outlook.com 192.168.1.13 with dyararco.duckdns.org

Alexa Skills -> Create skill (e.g. Alexa13). SmartHome -> provision your own
AWS; Create role, AWS Service -> Lambda -> add 'AWSLambdaBasicExecutionRole' name it: AWSLambdaBasicExecutionRole-SmartHome
Create Lambda function (N. Virginia), Functions, Create Function, author from scratch - > function name (python 3.9 as run time) -> Expand default execution role and selected an existing role (AWSLambdaBasicExecutionRole-SmartHome)
Add trigger -> click Alexa Smart Home (get skill ID from Developer console) amzn1.ask.skill.f821d9fc-7788-4097-ae6b-98004f737c04
Clear the example code, and copy the Python script from: https://gist.github.com/matt2005/744b5ef548cc13d88d0569eea65f5e5b -> then click Deploy """ Copyright 2019 Jason Hu

Navigate to Configuration-> Environment variables: (required) Key = BASEURL, Value = https://dyararco.duckdns.org (Do not include the trailing /). (optional) Key = NOT_VERIFY_SSL, Value = True. You can set this to True to ignore SSL issues, for example if you don’t have a valid SSL certificate or you are using a self-signed certificate. (optional) Key = DEBUG, Value = True. Set this variable to log the debug message and to allow the LONG_LIVED_ACCESS_TOKEN (optional, not recommend) Key = LONG_LIVED_ACCESSTOKEN,

in Alexa Developer Console developer console, Your Skill ID: amzn1.ask.skill.ffc7776e-da07-4285-9ebf-d17ebb58d3bd Default endpoint: arn:aws:lambda:us-east-1:815421264176:function:Lambda_HA_13 North America: arn:aws:lambda:us-east-1:815421264176:function:Lambda_HA_13 Your Web Authorization URI: https://dyararco.duckdns.org/auth/authorize Access Token URI : https://dyararco.duckdns.org/auth/token Your Client ID: https://pitangui.amazon.com/ Your secret: anything Scope: smart_home

First run Test on Lambda function, result should be succesful and listing all devices from home assistant then do account linking on Develop console then account linking on alexa app

Open Alexa pp
go to your skills
go to Dev
skill should be listed e.g. Home Assistant _Pilot_1
Enable to use

HOme assistant config file: alexa: smart_home: locale: en-US endpoint: https://api.amazonalexa.com/v3/events client_id: https://pitangui.amazon.com/ client_secret: anything filter: include_entities:

switch.sonoff_100157b239_2
scene.Office

make sure lights are tagged as lights
make groups that you want Alexa commands to control
Expose these groups in the HOme assistant config file: above
