Marking as completed, as this is implemented by the third-party Ping.fm Plug-In.

This is implemented by two third party plug-ins:

1. Locale Ping.fm Plug-in
2. Locale GTalk Plug-in

Both of these are available on the Android Market.]

As Chris said, this can be accomplished using the “Locale Power Power Source Plugin.” Simply add a Battery condition to detect the battery level, and a Power Source condition to detect being unplugged. Please note that this plug-in requires Android 2.0 or later.

At long last Locale 3.0 introduces the Calendar condition to detect events on your Google Calendar, Exchange Calendar, or any other calendar supported by Android.

While Locale 3.0 is available for Android 2.2 or later, the Calendar condition requires Android 4.0 or later. To learn more about Locale 3.0, please see our release notes here http://blog.twofortyfouram.com/post/19303488607/locale-3-0
