Davek Sensor Instructions



Apple: iPhone version 6 or later with iOS 10+

Android: Android 8+; Optimized for Samsung Galaxy devices (performance may vary on other Android devices). Note that the app is not compatible with these devices: Huawei, One Plus, ZTE and Nokia.

SET UP: Attaching the sensor to your umbrella

Pull the battery tab from sensor. The sensor should flash for 10 seconds. Using your thumb, slide the top black magnet off the sensor. Do not try to lift the magnet off.


Once removed, keep the magnet and sensor separated (>2+ ft) so they are not attracted to each other. The magnet is strong and will forcefully attach itself back to sensor when close.

For best results, follow below placement for sensor, depending on whether you have a compact folded umbrella or long-shafted umbrella:

Hold sensor underneath canopy in position shown, depending on your umbrella type. Place black magnet on top of canopy over sensor location. The two parts will automatically join.

Download the free Davek Loss Alert app and sync to your umbrella

Download our free app (Davek Loss Alert) on your phone (via Apple App store or Google Play).

Start the app. Make sure you ALLOW all permission requests (location, notifications, etc.) during first launch. (Note: If you do not allow all requests, the app will not work. If you do not recall if you allowed these permissions after first launch, delete and reinstall the app again). For Location Permission, be sure to choose "Always Allow".

To set Location Permission to "Always Allow", follow the steps below:

FOR APPLE IPHONE (as of OS 13.1.2 or later):
- Go to Settings
- Scroll down list of apps and select Davek
- Tap on Location
- Tap on Always

FOR ANDROID (need to set only for OS 11 or later):
- Go to Settings > Apps
- Scroll down list of apps and select Davek
- Tap on Permissions
- Tap on Location
- Select Allow all the time

Place the phone near the umbrella (between 1 to 2 feet away). To pair the umbrella to the app, slide the ON/OFF button to ON. You should receive an activation message within 10 seconds: “Umbrella is connected".

You are now all set. You will be receiving an exit alert within 60 seconds after you walk out of umbrella’s range (approx. 30 ft). Once you receive a "Connection is lost" alert notification, you will need to return back to umbrella to reset the alarm. When you get close within < 2ft. of your umbrella, your phone will automatically reconnect within 30 seconds and send you a new activation alert.


The app/umbrella will remain paired unless you proactively turn off the connection (by switching the ON/OFF switch to OFF).

The sensor will go into sleep mode when the umbrella is unmoved after four hours and will wake automatically when the umbrella is picked up. You should re-pair your sensor with your umbrella if you have:

- Force quit the app
- Restarted your phone
- Updated your phone's operating system

To re-pair the sensor, restart the app and swipe the app's ON/OFF button
OFF and back ON near your umbrella. Make sure the activation notice "Umbrella is connected" displays.

Your Security & Privacy

If you are using an iPhone, you may periodically receive the following notification:

What it means:

Periodically, the app will run a quick location update to the phone. This action will keep the app active while in the background and confirm if there is a nearby active sensor/umbrella. Selecting "Always Allow" will permit the app to connect automatically whenever you pick up your umbrella, without the need to turn the system on manually (similar to how your phone will auto-sync to your car when you turn on the engine).

Does the app share my location info?

No, the app is a one-way transmission application—it only receives information and does not send, thus your location is never shared. However, if you prefer to turn this off, swipe the app’s ON/OFF switch to OFF to disable all location updates. You’ll need to remember to manually turn the system back on, however, when you want to resume umbrella tracking.
