Sensors in the SimpliSafe® system will issue a “Not Responding” error when they fail to check in with the Base Station for more than 24 hours. We typically see this happen for one of two reasons:

1. The battery within your Entry Sensor needs to be replaced

2. The Entry Sensor is too far away from the Base Station and is unable to communicate from its current location effectively

If the Entry Sensor was previously working and the issue suddenly occurred, it likely is the result of a dead or dying battery. We recommend starting with this step first, before troubleshooting your Base Station placement. If you change the battery or adjust the placement of your Base Station and still see this error, it’s likely due to a syncing issue between the sensor and Base Station. Removing your Entry Sensor from your system and adding it back should clear the error.

The Entry Sensor takes a single CR-2032 Lithium 3V battery and has a life expectancy of up to 5 years depending on placement and usage.

To change your Entry Sensor battery, slide the sensor up and off its' bracket. Then replace the lithium battery and slide the sensor back onto its bracket.

If your sensor is still offline after replacing the battery, skip to the section below for troubleshooting steps.

Is your Entry Sensor offline after replacing the battery?

If you find that your sensor does not come back online after replacing the battery, it’s possible that it may have been offline for too long. The best step would be to remove the sensor from the SimpliSafe® Mobile App and then add it back to your system.

To remove your Entry Sensor:

1. Open the SimpliSafe® Mobile App on your phone or tablet

2. Choose My System from the bottom navigation bar

3. Select Device Settings

4. Tap on the sensor you wish to remove

5. Choose ‘Remove Device’

Once you have removed your sensor, you can add it back using our Installation Guide.

Your Entry-, Motion-, and Glassbreak Sensors come equipped with several modes that can help you with arming your system, disarming it, and triggering an alarm event the moment the sensor is triggered. Below you can learn more about what each mode does and how it impacts the usage of your system. Scroll to learn more, or use one of the anchor links to go to that section directly.

• Entry Delay

• Exit Delay

• Instant Trigger

Entry Delay

When enabled, the Entry Delay is the amount of time between when a sensor is tripped and when the alarm begins to sound when your system is in an armed state. That way, you have time to disarm your system without the alarm immediately going off. Once a sensor is triggered, your Keypad(s) will begin to beep, indicating that the system is counting down to the predetermined time at which the alarm will sound.

The Entry Delay can be set anywhere from 0 - 255 seconds. The default setting for your system is 30 seconds. It can also have different settings for Home and Away modes.

The warning ‘Sensor Not Responding’ for a Temperature Sensor can be caused by a couple of things, including a low battery or a weak connection between the device and the Base Station.

As a first step, we’d recommend ensuring that the battery is correctly installed. To do this:

1. Slide the sensor off its bracket by pushing it towards the wall and up

2. Remove the battery from the Temperature Sensor

3. Wait 15 seconds, then reinstall the battery again

4. Then, test the Temperature Sensor by placing your system into Test Mode using your Keypad.

1. Menu > Enter Master PIN > Test Mode

5. Press and release the button on the Temperature Sensor. The Base Station should announce “Temperature Sensor” and the timeline should show “Temperature Sensor Test” on the SimpliSafe Mobile App.

1. If you do not hear the Base Station respond, the battery within the Temperature Sensor may need to be replaced.

1. The Temperature Sensor takes a single CR-2032 Lithium 3V battery.To replace the battery, slide the sensor up and off its bracket to expose the battery compartment. Then replace the battery and slide the sensor back into place.

If you have replaced the battery and are still encountering the ‘Sensor Not Responding’ error, it likely is the result of a weak connection to the Base Station. A weak connection to the Base Station can often be caused by something environmental, like brick walls or dense home construction.

To test this, temporarily move the Temperature Sensor closer to the Base Station and see if the error stops. If the sensor does work in a new location, it is likely the result of the environment near the prior location that is causing the conflict. You’ll have two options from here; Keep the sensor in its’ new location closer to the Base Station, or try to identify and clear the interference in the sensor's existing location. If you choose to keep the sensor in the location where it has encountered the error, you’ll want to look for environmental factors, such as dense building materials, or wireless devices that are nearby that could be interfering with the RF signal between the sensor and the Base Station. If you have any devices that output a wireless signal, we recommend trying to keep them at least 3-5 feet away from your sensor. That should help to clear up communication between the device and the Base Station.

If your Water Sensor is showing as offline on the SimpliSafe® Mobile App, this is an indicator that the battery within the device needs to be replaced. 

The Water Sensor takes a single (1) CR-2032 Lithium 3V battery and has a life expectancy of up to 5 years depending on placement and usage.

To replace the battery, twist the bottom and top apart and replace the battery inside. To close it again, make sure that the grooves are aligned before twisting it shut. 

Please note that the error may take up to 24 hours to clear from the SimpliSafe® Mobile App after taking these steps. If you want to bypass that timeframe, you’ll need to follow the steps below to remove the Water Sensor from your system and then re-add it.

To remove your Water Sensor:

1. Open the SimpliSafe® Mobile App on your phone or tablet

2. Choose My System from the bottom navigation bar

3. Select Device Settings

4. Tap on the sensor you wish to remove

5. Choose Remove Device

Once you have removed your sensor, you can add it back using our Installation Guide.

Glassbreak Sensors are programmed to listen for the specific frequency of windows breaking. They're even sensitive enough to know the difference between a plate breaking, and a window breaking. Inside SimpliSafe’s Glassbreak Sensor is a small microphone that is calibrated to react to the sound of the glass being struck and then breaking. Pane glass has a certain sound frequency when smashed, which the sensor hears and then trips the alarm. The sensor is listening for the initial “thump” of the glass being struck, which in effect “wakes” it up, and the sound of the glass breaking micro-seconds later trips the alarm.

When a Glassbreak Sensor detects broken glass, the entry countdown will begin. This is dependent on your arming state and the alarm mode you set for it under the Glassbreak Sensors Settings Menu. The entry countdown by default is 30 seconds, however, this can be adjusted at any time within the SimpliSafe® App.

You can customise the entry countdown settings by going to:

1. Open the SimpliSafe® Mobile App on your phone or tablet

2. Select Device Settings

3. Choose your Glassbreak Sensor from the list of available sensors

4. Under Alarm Mode select your arming state and adjust the settings, as needed

If the system is disarmed within 30-60 seconds of the initial alarm signal, this will be considered a false alarm by our monitoring centre. That means you will not receive a phone call and if this is the only sensor that has triggered no guard dispatch will take place.

If the system is not disarmed before the time elapses, an alarm will sound. Depending on your monitoring service plan, two things will happen at once.

The Emergency Contacts for your system will receive a phone call from our monitoring centre to verify the status of your home.

If the alarm is not canceled within the grace period, the Emergency Contacts will receive a call from our monitoring centre. During this call you will be required to provide your Safe Word to the agent you speak with. Please note that providing the wrong safe word, or no safe word will result in a request for dispatch. You won’t be told you got it wrong to protect anyone who may be under duress. Additionally, missing the phone calls to your Emergency Contacts will also result in a request for guard services to the location that your system is registered to.

We encourage you to save the monitoring centre numbers to your phone. The numbers in which Securitas call you from:

• Securitas will contact you from: 0330 184 0444

• You can contact Securitas on: 0303 330 0369

• Test Mode Automated Call: 01908 644505

Once saved to your phone, you’ll also want to allow us access to bypass Do Not Disturb and Silent Profiles. This allows for Critical Alarm Notifications to get through to you, regardless of your phone’s volume or profile status.
