Sensor Readings Incorrect Or Show An Object That's Not There

The number one reason for incorrect sensor readings is that the sensor is hitting an object unexpectedly. If you have a step, hitch, or otherwise protruding bumper, it may cause a false reading from the sensor. 

Here are some solutions:

1. Invert the sensor (turn upside down). Make sure you select the "Invert Sensor" option in the settings menu so the readings are inverted and read correctly after making the flip. 

2. Use the small Allen key included in the key on the holes to the left and right of each sensor: Turn left to loosen. Adjust the sensors up with the app running to see how it affects the readings (don't stand in front of the sensors), then hold the sensor in position while turning the Allen key clockwise to lock the sensor into its new position. 

Most false sensor readings are the sensor pointing downwards and hitting the ground, bumper, or hitch. Follow one of the two solutions above for an easy fix. 


My App Doesn't Connect To My Device

If you are trying to add the TAP button or sensor device and it keeps spinning without connection, it could be related to a widely reported Bluetooth Issue on S9. Please see these instructions on how to fix, then proceed to the steps below. 

 Here are some troubleshooting tips if you suspect a bigger issue.

 When the app is not connecting to device after paired, it may have one of the problems below:

1. App problem: App can not connect to device. (Try to reboot the App and/or the phone itself.)

2. Device problem: The device can't connect. (Try to re-power the device). 

3. Bluetooth signal: The distance between phone and device is too far and the signal is not good enough for communication. Lastly, the antenna in the product could be defective and it would be covered by hardware warranty.


The TAP Button And Auto-Launching The App

The TAP button automatically launches your app on Android and sends you a push notification on iOS that you can use to tap (the notification) and launch the iOS app on your phone instantly. If this doesn't work, make sure the app is running in the background and the blue status bar indicating location services is on. 

Pair your TAP button from the "Manage Devices" section, which you can access from the settings page in the app itself.

Add the TAP button from the "Manage Devices" page where it says "TAP Buttons", then click "Add TAP Button" to look for a nearby button you can pair with and use to auto-launch the app going forward. 

Say "Hey Siri, Launch FenSens" to launch the QuickLaunch notification on iOS or "Open FenSens" to launch the app on Android.  You can also touch your home screen button on iOS to launch SIRI, then use the above described voice command to launch. 
iOS users: If the APP is not running in the background, TAP the QuickLaunch button once to wake it up, then TAP the QuickLaunch button again to receive a push notification to auto-launch the FenSens device. Some TAP button actions can be limited by the platform or by the operating system, especially iOS which can prevent running background processes.

It's Asking For A Share Code, What Do I Do?

Make sure you record your share code from Settings > Manage Devices > FenSens > Click On The Device. You should be able to see your device details and the share code associated with this. Provide this share code to friends and family for them to use when signing up and connecting with your device.  If you can't get in, then please contact info@FenSens.com for support and provide the device ID which should show up as FenSensXXXXX in your phone's Bluetooth nearby settings. 

How long is the battery life?

The battery lasts about 5 months and replacing the battery is as simple as popping off the battery housing. Batteries are universal AA size and can be replaced with any AA battery.

How do you prevent theft?

FenSens comes with a set of security screws. FenSens owners are the only ones with the unique (included) screwdriver that can take it off the license plate. Also includes anti-theft software where device only works with your phone and tracks your car if it's lost or stolen, right on your app. 

Do I have to do anything after installing to use it?

The included QuickLaunch button launches Android application instantly or sends a push notification to open the app if you are using iOS. The Android app starts providing you feedback without you having to do anything and the iOS app works by simply clicking the push notification you receive.

My Device Takes Too Long To Connect

We have found this is typically because the user attempts to turn on their Bluetooth settings while in the car. If the user turns off Bluetooth and then goes in the car, turns on the Bluetooth again, and opens the APP when they want to park, It might need a few seconds to connect the sensor device. If the signal is not strong in the car, it might need more time to connect.

We suggest to turn on Bluetooth all the time which doesn't use much battery at all from the phone, the APP can then connect to device when the user gets close to car and the app will connect much more quickly. Our device has a powerful antennae, but not every phone does, so it takes a bit to connect usually on the smartphone side. Avoid this by having your Bluetooth turned on already. 

What is the effective range or object detection capabilities?

The FenSens can detect objects about 10 feet away and guide you safely to less than 1 foot away from them. When an object is detected, the response is very quick, but please pay attention to any feedback warnings and always back up carefully. While FenSens helps assist in safe parking, please pause for one second, look behind to see if your path is clear, then move.

What type of vehicles does it work for?

FenSens is perfect for all consumer and commercial fleet vehicles not exceeding 30 feet in length. If your car has a recessed license plate frame above the bumper, you might need the FenSens Truck version, which has the sensors positioned at the top of the FenSens device. We advise the owner of any vehicle with a license plate frame higher than 4 feet off the ground to test the vertical range of the sensor before using, as it may have trouble seeing objects below 2 feet.

Can I pair multiple phones to it?

Multiple users can be connected to one FenSens device. The original account holder can go to "Manage Devices" from in their settings menu, click on the device, and copy the share code to send to friends and family. While signing up the friends or family input that code during "LOGIN". 

When using the device the TAP QuickLaunch button will work for the registered user that connects to it first. For Android, whoever is in range first will be prompted and capable of launching the app on their phone when the TAP button is launched. For iOS both users will receive a push notification when in range of the device, whoever hits the notification to connect first will auto-launch the app on their phone. 

My TAP Doesn't Launch

Please refer also to the FAQ above. Make sure you have location services turned on as the iBeacon will not work properly if your location services are turned off on your phone. In that case the TAP will not know you are close to the vehicle. Please turn on your mobile phone's location services.  

Also, TAP the button once to pull the app into the background, then TAP the button a second time to launch the app (or receive a click-to-launch push notification on iOS).  Also, try replacing the batteries (they are CR2032 3V lithium cell batteries. If your battery indicator shows 0% or the button doesn't show up in your Bluetooth nearby settings, then the battery is likely dead. 

I'm Not Receiving Audio Alerts Or TAP Button Notifications

For any button related issues, please see above FAQ's and make sure to check all permissions in APP. You should also turn on Location Services on your phone as our beacon uses this to determine if you are close to the device and send a push notification. 


Here are the best ways to troubleshoot your audio alerts not working: 


1. Turn on the sound from the mute switch to the left side of the iPhone.

2. Turn on the sound on from within the parking page in APP.

3. Adjust the volume to a maximum in the parking page.

4. Make sure there is a target within 2.5 to 3 meters from your car. The app will only beep if an object is detected in that range, but not further. 

Can I Take The Button Out Of The Holder?

Yes, the button is fully removable from the holder. Simply pinch the holder back to loosen the button, then use both fingers to carefully pluck the button from the button holder. Use the included 3M tape that came with your screw kit to place the button anywhere you want in the vehicle. 

How do I use the TAP button?

The TAP button launches the app automatically on Android and will send you a push notification on iOS. For best operability, please make sure you accept all permissions the app asks for and for iOS have the app running in the background. One tap on Android will launch the parking sensor page, another tap will take you out of the parking page to the home screen. A long hold of 4 seconds on Android or iOS will put the button into pairing mode if you are having trouble pairing with the button.  Also, feel free to say "Open FenSens" to launch the app on Android or SIRI to launch on iOS. 

How do I set the sensor from front to back (or vice versa)

You can set your sensor to the front or back during the setup process initially and anytime from the "Manage Devices" section of the Settings page. On the "Manage Devices" page, click "FenSens" under the devices section. This will pull up a screen that shows the paired devices, click the one you want to reposition, hit the delete button, then add it again, but this time to the back of the vehicle when it walks you through setup.  

TAP QuickLaunch Isn't Working On iOS

Make sure you accept all the necessary permissions in the app and set your Location settings on your phone to allow FenSens to use location "Always", not while using. The TAP button performs best when you have the FenSens app on in the background of your phone. 


If you are having issues pairing, then make sure to do a 5 second hold on the button to put the button in Bluetooth pairing mode. The button should appear available to pair with under Settings > Manage Devices > Tapp > Add Tap > Connect. 

What's The Best Way To Use 3 Or More FenSens Devices?

Each FenSens account is designed to manage 2 devices on 1 car for now. We will likely update this in the future, but for now we would recommend connecting only up to 2 FenSens devices (Front And Back) to 1 vehicle on one user account. 

Trouble Adding Two Sensors?

FenSens is designed to have 2 devices on 1 car (front and back) or with one mobile phone or user account. You can place multiple devices on other cars, but we would recommend a separate mobile phone or user account to be used with each car that has devices on it. This is so FenSens can properly tell that you back sensor on car #1 is different than the backup sensor on car #2. 

I Don't Want To Mount The TAP Button On My Steering Wheel

The TAP button can be taken out of its included holder and placed anywhere in the vehicle. Carefully pinch the bottom ring of the button holder to loosen the top, then carefully pop the button out of the holder. Use the included 3M tape from the screw kit to mount the button anywhere you would like in the car.
