Operating your DOOR Smart Home Sensors

Once your DOOR Smart Home Sensors are installed, you manage them all the same way in the DOOR App: check their status, set up alerts, view history, and replace batteries when they run low. This article covers the operations that are common across every sensor. For what a specific sensor measures, see its own "Using your…" article.

About this feature

Every sensor appears in the DOOR App under Devices → Controls, listed under the Unit it's assigned to. Tapping a sensor opens its dashboard (current status and key info), its history log, and its settings. Because sensors report through the DOOR Hub, they only update while the Hub is online — if the Hub goes offline, sensors stop reporting until it reconnects.

Checking a sensor's status

Open the DOOR App, tap Devices, then Controls, and open the Unit the sensor is in.
Tap the sensor you want to check.
The dashboard shows its current reading — open/closed, motion detected, leak/no leak, or temperature and humidity — along with Connection (Online/Offline), Last Updated, Battery level where shown, and Location.

Setting up alerts

Each sensor has its own alert options under Settings:

Open and Close Monitor — choose Don't alert, opened, closed, or opened or closed. You can also set an open reminder that alerts you if the door or window stays open too long, with an optional continuous alarm.
Motion Detector — toggle alerts On or Off, and set a motion frequency timer so the sensor waits a set period before alerting you to motion again.
Leak Detector — set the alert interval (how often you're re-notified while a leak is present). Alerts arrive through the app, SMS, and email.
Leak Lasso — set the alert interval, and toggle the Beep sounder on or off.
Temperature and Humidity Sensor — set separate temperature and humidity thresholds (the range that triggers an alert) and the alert interval.

Viewing history

Every sensor keeps a Record Log under History — a chronological list of state changes and connectivity events. The Temperature and Humidity Sensor adds temperature and humidity graphs (24-hour by default, with daily, weekly, monthly, and custom date ranges).

Renaming a sensor

In a sensor's Settings, tap Device Name to give it a clearer name (for example, "Kitchen sink leak" or "Front door"). For the Leak Lasso, you can also set the Room it's assigned to.

Replacing the batteries

A sensor signals low batteries by blinking its status LED fast red every 30 seconds, and the DOOR App shows a low battery level on its dashboard. To replace them:

Open the sensor's housing or back shell.
Replace with the same battery type — 2 AAA for most sensors, 2 AA lithium for the Temperature and Humidity Sensor.
Close the housing. The sensor powers back on (LED blinks red then green) and reconnects through the Hub automatically.

Testing a sensor

You can confirm a sensor works without waiting for a real event:

Open and Close Monitor — open the door or window and watch the status flip in the app.
Motion Detector — walk across its field of view.
Leak Detector / Leak Lasso — bridge the electrodes (or wet the rope) with a damp paper towel, confirm the alert, then dry it off and confirm it returns to No Leak Detected.

If it didn't work

The sensor shows Offline — it reports through the Hub; if the Hub is offline, every sensor goes offline. See DOOR Smart Home Sensors troubleshooting.
You're not getting alerts — confirm the alert is enabled in that sensor's Settings and that DOOR App notifications are allowed on your phone.
