CALexa is an Amazon Alexa Skill which allows accessing CalDAV Calendars. It makes use of the Flask-Ask Python micro-framework developed by John Wheeler.

Hi,
first of all I want to thank Martin Riedl for sharing his code.
I've tried to install it on my system and had several problems, but got pretty far (I guess almost 99%).
My System: Xubuntu 16.04, OwnCloud 10.0.8, Apache 2, Cert via Let's Encrypt
Step one: Alexa Skill on Amazon Dev:
It seems Amazon changed their syntax some time ago. The provided .json is not accepted as it is. I've transformed it to the following which already includes all speech_assets and customSlotTypes... So you basically only need to paste the .json and don't need to add these things manually any more.

Step two: Running calexa.py on same server
I've Downloaded calexa.py and conf/config.json
In the config I'm not sure the URL has to be
https://domain.de/remote.php/dav/calendars/USERNAME/default/
or
https://domain.de/remote.php/dav/principals/users/USERNAME/
So I've tried both (first is my default calendar, second one are all of my calendars).
I've also installed the dependencies via:
pip install flask-ask
pip install caldav
pip install cics
When I run python calexa.py this is the output:
/home/USERNAME/.local/lib/python2.7/site-packages/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
warnings.warn(warning, RequestsDependencyWarning)
* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
So it seems to run. I've ignored the warning cause it only seems to be a speed issue.
Using a local Browser on http://127.0.0.1:5000 I get this:
Method Not Allowed
The method is not allowed for the requested URL.
Since there is no parameter I've expected some error at least.
Calexa.py Output in console add's the following line:
127.0.0.1 - - [25/Jul/2018 10:15:56] "GET / HTTP/1.1" 405 -
Step three: Reach Calexa fom outside
Activated proxy module for Apache
sudo a2enmod proxy
sudo a2enmod proxy_http
VirtualHosts:
<IfModule mod_ssl.c>
<VirtualHost _default_:443>
ServerName domain.de
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
LimitRequestBody 0
SSLEngine on
SSLProxyEngine On
ProxyPreserveHost On
ProxyPass / http://localhost:5000
SSLCertificateFile /etc/letsencrypt/live/domain.de/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/domain.de/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/domain.de/chain.pem
</VirtualHost>
</IfModule>
Of course Port 433 has NAT forwarding to my server. I'm now able to access from outside, getting the same Method Not Allowed message.
Endpoint in Amazon Dev is: https://domain.de
This is what I get when I try to open Calexa with my Echo Dot. (Alexa starte Calexa)
Bei der Antwort des angeforderten Skill ist ein Problem aufgetreten.
Free translated: There was a problem with the answer of the skill.
I can see the requests reaching calexa.py as it outputs the following:
127.0.0.1 - - [25/Jul/2018 10:30:25] "POST / HTTP/1.1" 400 -
127.0.0.1 - - [25/Jul/2018 10:30:26] "POST / HTTP/1.1" 200 -
So it seems I'm almost done. Maybe my conversion of the .json is not correct or the calexa.py is configured wrong. Maybe someone can help and hopefully I can help others with my detailed descriptions.
Looking at the most recent commits, and the 100% unanswered open issues, I should have realized this was a dead project before I wasted my time.
Shame, I had such high hopes! If it ever gets revived, or anyone cares to fork it and get it up and running again, I would be super keen to give this another go.
Anyway, thanks for the original effort etc. I don't mean to sound like an ingrate.
Github needs some system of flagging dead projects though. Or I just need to be more discerning before delving in to such things.
Such is life.
I feel like Marvyn from Hitchikers today.
Peace out

On the alexa skills test page I get the following error:

I made the self signed cert 1:1 following Amazons directions from their page here:
Also I'm not using nginx, but apache. My config looks like this:

I think that about covers all the info.
Anyone have any idea whats going on here?
Config looks perfectly fine to me..
I'm trying to install calexa. When starting calexa.py the following error appears:
sudo python /opt/calexa/src/calexa.py
Traceback (most recent call last):
File "/opt/calexa/src/calexa.py", line 13, in

flask-aks is allready installed:
sudo pip install flask-ask
Requirement already satisfied (use --upgrade to upgrade): flask-ask in /usr/local/lib/python2.7/dist-packages
Cleaning up...
Any ideas?
Sebastian
Solved it. All dependencies installed as errors thrown by the script. Just straight forward
"sudo pip install xyz..."
Greetings, Sebastian
Hi there,
thanks for making it possible to use Alexa with a CalDAV calendar. I run an ownCloud server which has an integrated CalDAV server. By reading the README.md I couldn't figure out where CALexa has to be installed. Is it possible to run it on a server in your local network? Does it have to run on the same server as the CalDAV server runs?
Best regards,
Konze
Hello,
first of all thank you for this skill! But I have a Problem:
I created the skill until the testing phase without publishing it. Testing on my device is enabled but when I ask it about my calendar, it just responds "You have not setup any calendar. Please view settings in the app"
