While waiting for Things Touch to officially support push notifications I hacked my own solution based on Prowl and my own Ruby library for Things, things-rb.

Installation

1. I’ve setup Dropbox to share my Things database betweeen my laptop and a computer at home which is always online.

2. Buy and install Prowl on your iOS device.

3. On the home computer/server, install things-rb:

   $ (sudo) gem update --system # if you're on an older RubyGems version
$ (sudo) gem install things-rb

4. ..and the prowl gem to talk to the Prowl API

   $ (sudo) gem install prowl

5. Save this file somewhere (like ~/bin/prowl_things.rb)

6. Setup a cronjob to run the script as often as you’d like. Mine runs every weekday at 8:45 am.
