Once you have configured a few devices or need to configure many similar devices, you can quickly copy the settings from one entry to a new entry quite easily using the Copy From button on the IPSentry Entry Editor.
After you hit this button, you will be presented with a list of existing entries from which you can select. After selecting one, all of the settings, including alert options and the down time schedule, will be copied into the current item being edited. You then need only make minor adjustments unique to the new device.
This option can save a great deal of time when configuring many similar devices.
