This is a Locale plug-in and Tasker plug-in.
It detects if a hostname is reachable. For instance, you can detect when a given computer is turned on or off on your home network.
This condition can be restricted to work on Wi-Fi only.
This plug-in is highly customizable:
-Hostname or IP address to ping
-choose the trigger to be a “pingable” or “unpingable” condition
-choose the timeout
-choose the number of retries
This Locale plug-in is from the same developper as:
-Locale/Tasker Ping Plug-in
-Locale/Tasker Light Sensor Plug-in
-Locale/Tasker Screen On Plug-in
-Locale/Tasker Screen Off Plug-in
-Locale/Tasker Proximity Sensor Plug-in
-Locale/Tasker Proximity Click Plug-in
This is not a standalone app. It requires Locale by TWO FORTY FOUR A.M. LLC or Tasker by CRAFTY APPS to work.
For Tasker users: Once installed, you will find this plug-in under the "State/plug-in" category, not under the "Event/plug-in" one.
