This is an application that lets you send all notifications to your Pebble smartwatch. You can exclude certain applications or exclude all save a few.
For basic troubleshooting steps (like if you can't get notifications to send), please visit: https://github.com/dattas/pebble-notifier/wiki/Troubleshooting
This is also bridge between the Pebble application and Tasker. It will let you send notifications of your making to your Pebble. Simply fill out the title and body of the message you want sent to your Pebble and off you go!
