Disclaimer

No warranty or liability is given for any damage caused by this software. Perform any of the steps described here at your own risk.

Prerequisites

Server

1. A device in the network (such as raspberry pi) with a docker daemon installed which is accessible in the network.

Kindle Client

1. A jailbroken Kindle of any generation. Instructions on jaibreaking your kindle are all over the internet, for example here.
2. For setup of the shell script usbnet needs to be installed on the kindle. Instructions can be found here.

Installation

Server

1. Ensure to update the variables in the following files:
   • app.py main application:
     • payload.lat: Your latitude
     • payload.lon: Your longitude
     • payload.appid: The api key for weather forecasts. You can generate it for free on openweathermap.org
     • payload.lang: The language you want to display
     • CITY: The city you want to display in the dashboard.
   • /googlecalendar/ folder: Contains Google calendar integration
     • credentials.json Google Calendar credentials that can be generated in your Google cloud console. Choose the type web application and replace the values in client_id, client_secret and refresh_token with the generated values.
     • controller.py Replace the values in CALENDERIDS with the ids of the calendars you want to display.
   • /notes/ Google task integration
     • controller.py Replace the values in tasklistId with the id of the tasklist you want to display.
     • credentials.json replace the values in client_id, client_secret and refresh_token with the values from your Google Cloud Console
   • /mail/controller.py Home Assistant integration (disabled by default as this is highly customised):
     • HASSURL: The REST endpoint of your smart home server
     • HASSTOKEN: Your Home Assistant refresh token
     • HASSVARISMAIL & HASSVARTIMESTAMP: Custom variables to be displayed on the screen.
2. Navigate to the server folder and build the docker image:

docker build -t flask-kindledashboard .

3. Start the container. Replace 5123 with the port you weant to expose:

docker run -p 5123:5000 --restart unless-stopped -d --name kindledashboard flask-kindledashboard 

4. Navigate to the server url and append port and /kindledashboard suffix (e.g. http://192.168.178.63:5123/kindledashboard). The png should be generated after several seconds. Once the kindle devices are set up you can review the client logs in the endpoint /kindledashboard/logs.

Kindle Client

1. Adjust the dashboardscript variables with the values from your network.

• Set your server IP in the SERVERIP and your port in the SERVERIPPORT.
• The script is executed up to every 15 minutes. To change the frequency adjust the values in F5INTWORKDAY and F5INTWEEKEND.
• You can adjust further variables such as HOSTNAME to distinguish between several kindle devices in your network.

2. Save your changes and copy the content of the kindle folder on the kindle. You can use the standard kindle mass storage to do so. This implementation uses the folder /mnt/us/scripts as destination folder. The folder /mnt/us is the mass storage's base folder.
3. Connect to your Kindle using SSH. If you are asked for a password try mario or one of the common root passwords.

ssh [email protected]

4. Make the dashboardscript.sh file executable by running the following command:

chmod 700 /mnt/us/scripts/dashboardscript.sh

5. Make the root filesystem writable by running:

mntroot rw

6. Copy the dashboard.conf file to the /etc/upstart folder:

cp /mnt/us/scripts/dashboard.conf /etc/upstart/

7. Restart your kindle and wait 150 seconds for the script to start. You should see the generated png shown on the kindle screen.

If you want to use the regular Kindle UI, connect to the kindle using ssh and delete the file /mnt/us/scripts/dashboard.conf. After restarting the device you can use the standard Kindle UI again.
