Using your DOOR Leak Detector and Leak Lasso
DOOR offers two water leak sensors: the Leak Detector (a spot sensor placed on the floor) and the Leak Lasso (a flexible rope sensor laid along a baseboard or around a pipe). Both detect water and send an alert to the DOOR App. This article covers using both devices.

After a leak is detected, the sensor electrodes can corrode. Clean or replace the sensor after each leak event.
If you receive a leak alert
- Check the sensor location immediately.
- Identify and shut off the water source if possible (turn off the shut-off valve under the sink or the main water shut-off).
- Contact your property maintenance team — they can assess the source and respond.
- After the area is dry, clean the sensor probes with a dry cloth before placing it back in service.
Opening the device controls
- Open the DOOR App and tap the Controls tab.
- Tap the Leak Detector or Leak Lasso.

Set how often the app resends a notification if water is still detected. A shorter interval means more frequent reminders until the sensor is dry.
Beep (Leak Lasso only)
Toggle whether the Leak Lasso emits an audible beep when a leak is detected, in addition to the app notification.
History
The History tab shows a chronological log of all leak events and connection status changes.
