Hi everyone,
I’ve found an easy solution to show values (like temperature, door open/closed etc.) inside your Notification Center on Mac OS X. Here’s what it looks like:

In order to get this running on your machine, install Today-Scripts (https://github.com/SamRothCA/Today-Scripts Today-Scripts) first. Then open the following URL: http://USER:PASS@pimatic/api/variables/ (Remember to change user/pass/url, of course)
There you’ll see a list of the names of the values you will be able to use later. In my case, I chose temp-aussen-strasse.temperature which is the name of my outside temperature. Afterwards, add the following script inside the Today-Scripts section of your Notification center:
tput setaf 1; curl -s "http://USER:PASS@pimatic/api/variables/temp-aussen-strasse.temperature" | tail -n 5 | head -n 1 | sed 's/\"value\":\ //' | sed 's/\ \ \ \ //' | sed 's/,//' | sed 's/$/\ °C/'
Same as before: Don’t forget to use the correct URL; that means that you need to change your username, password, address and of course the name of your value. The same should go for any other temperature values; you’ll just need to change the name of the value.
If you want to change the color of your output, you might want to do a quick google search for “tput”. In the example above, I used the colourcode 1, which colours your output red.
Feel free to ask any questions if you can’t get this running or if you want to display other values!
Cheers

P.S.: I know that the regular expressions used are ugly, but at least it does the job.
