This idea of this project is to make an adapter of my own smarthome to Yandex.Alice dialog platform.

It consists of four main parts:

1. OAuth2 implementation. It is based on the great authlib¹ library, and own integration with aiohttp².
2. More or less full Yandex.Alice platform protocol implementation³⁴.
3. aiohttp⁵ based web server, providing necessary authorization, routing and access to devices.
4. Some set of devices implementation. They are mostly the ones, that I have but can be used as base and/or inspiration for writing your own device adapters.

This server is intended to let you make your own secure smarthome platform. No public access. No open access to MQTT or anything else. No proprietary clouds from some faraway country. You own your devices and give access to them only to a single specific service on your own choice.

To make your own smarthome platform you need:

1. Register your own skill on the dialog platform⁶. Do not forget to make it private.

2. Next you need your own server (we're making private platform after all). You will need some https certificate (e.g. Letsencrypt). Choose subpath on the server, that'll host our platform, e.g. /alice/. Take a look at example config for nginx:

   upstream alice {
       server 127.0.0.1:8888;
   }
   
   server {
       listen 443 default_server ssl http2;
       listen [::]:443 default_server ssl http2;
       port_in_redirect off;
   
       ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem;
       ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem;
       # ... other default ssl and server params
   
       location /alice/ {
           proxy_pass http://alice;
           proxy_set_header Host $http_host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Host $server_name;
           proxy_set_header X-Forwarded-Proto $scheme;
           proxy_redirect off;
           proxy_buffering off;
       }
   }

   Here 127.0.0.1:8888 is the address of the interface platform will listen, and mydomain.com is the domain we use.

3. Bootstrap the app:

   $ git clone https://github.com/torkve/sorokdva-smarthome
   $ cd sorokdva-smarthome
   $ python3 -m virtualenv ve
   $ source ve/bin/activate
   $ pip install -r requirements.txt
   $ cp app.toml.example app.toml

4. Run app in debug mode:

   $ export PYTHONPATH="."
   $ python dialogs/app.py -p 8888 --prefix /alice/ --proxy \
       --db db.sqlite \
       --debug

5. Debug mode allows us to register users. We will use this feature only once to register a user for Yandex.Alice platform.

   Navigate to https://mydomain.com/alice/auth

   Remember to replace mydomain.com with your domain, and /alice with your selected prefix.

   Register some user, e.g. with name alice_user.

   Login as this user on the same page. You will see the "Create client" button.

   According with the Alice platform, some fields must be fixed:

   • client URI: https://dialogs.yandex.ru
   • redirect URI: https://social.yandex.net/broker/redirect
   • allowed grant types: authorization_code and refresh_token (split by newline)
   • allowed response types: code

   You can define any space-separated scopes if you wish to separate some privileges in the future.

   Client name may be anything.

   Write down client_id and client_secret of the app created.

6. Edit file app.toml to configure devices you have. Take app.toml.example for inspiration.

7. Restart app without debug mode:

   $ python dialogs/app.py -p 8888 --prefix /alice/ --proxy \
       --db db.sqlite

8. Now you may edit you smarthome skill⁷ and add backend endpoint url to the skill: https://mydomain.com/alice.

9. Open account linking settings and set client identifier and client secret with the values you wrote in step 5.

   Set authorization url to https://mydomain.com/alice/auth

   Set token endpoint to https://mydomain.com/alice/oauth/token

   Set refresh token endpoint to https://mydomain.com/alice/oauth/token

   Set scopes to the scopes you selected while creating the app.

10. Add your skill in the Yandex app. It will require you to authorize with the login you created in the step 5, then will request oauth access.
11. After that you should see your devices in the Yandex app and Yandex.Alice will respond to your requests.

I want easier way, why so many steps and no Docker? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
