Interference Issues

If your SimpliSafe Entry Sensor keeps going offline, the issue may be related to interference.

Your SimpliSafe Base Station typically has a 400-foot range for sensors.

However, walls or large solid objects, as well as electronic interference from other wireless devices, can reduce this range.

Dense objects obstructing the signal path between the sensor and the Base Station, such as furniture or appliances, could significantly reduce the base station’s ability to connect to your sensors.

There is also the matter of electronic interference. Other nearby wireless devices, such as remote-controlled garage door openers or wireless weather stations, might also compete for the same airspace, leading to interference.

You only need to reposition the sensor for a clear line of sight and remove potential obstructions like new furniture or appliances.

Lack of Contact with the Base Station

Your SimpliSafe system is designed to trigger an alarm every time a sensor loses connection with your base station for over 24 hours. If this happens, the sensor that lost connection with the base station could appear offline on the app, even if the sensor’s batteries aren’t dead.

One of the most common reasons this could happen is if you relocated your base station to the sensor or both.

SimpliSafe Entry Sensor Not Chiming

When your SimpliSafe system is disarmed, and an Entry Sensor is opened, a chime is triggered at the Base Station. This chime serves as a notification, alerting you to the potential intrusion or the opening of a monitored entry point in your home.

It’s a feature to keep you informed about activity even when the system is not actively armed.

If your SimpliSafe entry sensor is not working, here are some potential reasons why.

Your Chime setting has been toggled to OFF.

You can quickly turn it on and adjust it to MEDIUM or HIGH using the SimpliSafe Mobile App, Web App, or Keypad.

On the SimpliSafe Mobile App, follow these steps

• Open the SimpliSafe® app on your phone or tablet.
• Select “My System” from the bottom navigation bar.
• Go to “Base Station Settings.”
• Scroll to “Entry Sensor Chime.”
• Adjust the volume using the slider.
• Click “Save” in the upper right corner before exiting.

On Keypad

• Press “Menu” on your Keypad.
• Enter your Primary PIN.
• Choose “System Settings.”
• Select “Chime Volume” and adjust as needed.

On Web App:

• Log in to the Web App.
• Select “System” from the left-hand navigation bar.
• Under “Additional Settings,” find “Entry Sensor Chime.”
• Use the drop-down menu to adjust the volume.
• Click “Save Changes” at the bottom of the screen before exiting.

Sensor placement

Sensor placement is crucial for entry sensors in a security system like SimpliSafe to function adequately. The position of the sensor relative to its corresponding magnet and the monitored entry point (e.g., door or window) can impact the system’s performance.

Ensure the Entry Sensor is correctly aligned with the magnet when the door or window is closed.

Confirm no obstacles or misalignments are affecting the sensor’s functionality.

Also, consider restarting your SimpliSafe system by unplugging the unit, removing and reinstalling the rechargeable batteries, and allowing it to reboot.

If challenges persist, don’t hesitate to seek support from SimpliSafe for further assistance.

SimpliSafe Entry Sensor Not Working After Battery Replacement

If your SimpliSafe Entry sensor isn’t working even after battery replacement, there are other reasons.

You Have the Wrong Batteries or Inserted Them Wrongly

Suppose your sensor stops working immediately after you replace its battery. In that case, you probably have the wrong type of battery or have inserted it incorrectly.

SimpliSafe entry sensorsuse a single (1) CR-2032 Lithium 3V battery.

Poor connections with the base station

Suppose your SimpliSafe entry sensor does not respond or work after the battery change. In that case, it might be due to faulty connections with the base station.

Check for physical obstacles like walls or heavy appliances, and look for sources of wireless interference such as remote-controlled garage door openers, wireless weather stations, or baby monitors.

Once interference sources are identified, work on minimizing their impact by repositioning the base station or sensor to minimize obstacles. Adjust frequencies or relocate other wireless devices to reduce interference.

Addressing these will help ensure that the connections between the entry sensor and the base station are secure and interference is minimized, improving overall system performance.

You need to Reset the Sensor.

Resetting your SimpliSafe Sensor is one of the surest ways to fix minor issues with the device.

If you recently replaced the batteries in your sensor and the device suddenly stops working, try resetting your sensor.

Here is how you can do that:

• Unplug the Base Station
• Using a screwdriver, open the battery cover on the entry sensor.
• Remove the battery for about 15 seconds, then re-insert and secure the cover.
• Tap the reset button on the sensor for at least 10 seconds until you hear the indicating beep tone.

If the issue persists, conduct a test by opening the door to see if the sensor triggers the alarm. If it fails to do so, the sensor may be defective and needs replacement.

What to Do if a SimpliSafe Sensor Is Not Responding

When a SimpliSafe sensor is Not Responding, the issue may stem from a battery problem or a weak connection. Follow these steps to solve the issues

1. Replace Batteries:

Begin by replacing the sensors’ batteries.The Entry Sensor uses a single (1) CR-2032 Lithium 3V battery, which can last up to 5 years, depending on usage and placement.

If you have the wrong batteries, your sensor won’t work.

Even if you have suitable batteries, your base station will still not work if you insert them incorrectly.
