All features of Dome's Door Sensor are available within HomeSeer. Please make sure your Z-Wave plug-in is up to date before continuing (at least version 220.127.116.11). See Figure 1 for a screenshot of how the the Z-Wave log should appear after successful inclusion - if you see any errors, see this article about including battery powered devices into HomeSeer.
After successful inclusion, the Notification status (whether or not water is present) can be used as an event trigger or condition. See Figure 2 to see how the Leak Sensor and all associated virtual devices will appear in the home page.
In Figure 3, an event is triggered when the Door/Window Sensor opens.
In Figure 4, a binary switch is turned on when the Door/Window Sensor opens.
