Setup

1. Create ssh keys for passwordless access

First prerequisite is, that you have enabled ssh on your Raspberry Pi. You can find instructions here: https://www.raspberrypi.org/documentation/remote-access/ssh/

After that to be able to get the data out of your Raspberry Pi without the need of entering a password, ssh keys need to be created (More info about that can be found here: https://www.raspberrypi.org/documentation/remote-access/ssh/passwordless.md). Open a terminal on your Mac and go to your home directory /Users// (Enter cd ~ in the terminal and press enter):

Now start the generation of the keys:

ssh-keygen

• Save the keys in the file /Users//.ssh/id_rsa when prompted - should be the default location
• Enter NO passphrase (just press two times ENTER when prompted)

Then copy the keys to your Raspberry Pi:

ssh-copy-id <USERNAME>@<IP-ADDRESS>

Now once for copying the file, the password needs to be entered. After logging in the next time on your Raspberry PI through ssh, no password is needed anymore.

2. getData.sh file for config

First of all you need to enter your username and hostname of your Raspberry Pi in the getData.sh file:

# Configuration\
username='your username'\
hostname='ip address or hostname of raspberry'

Afterwards you need to make the file executable: Open a terminal and go to the widget folder (usually located under /Users/<yourUser/Library/Application Support/Übersicht/widgets/raspberryData.widget/). Then apply the following:

chmod 755 getData.sh

3. Start the engines

If steps 1 and 2 were successful, then you should see already data of your Raspberry Pi on your widget on the desktop. Enjoy :) Now you can change the position of the widget in the index.coffee file:

# Position of the widget on your screen\
pos_top		= '180px'\
pos_left	= '330px'
