SimpliSafe Glass Break Sensor Offline – Fixed!

Tip: Follow our instructions in consecutive order!

1. Reinsert Your Sensor Battery

In case of a momentary failure with the SimpliSafe glass break sensor’s connection, you can address cellular issues by removing the sensor’s battery. 

Although all SimpliSafe extra sensor batteries typically last 3–5 years, wireless congestion is typically due to improper charge, which is worth checking.

Here’s how to access and remove the battery of the glass break sensor:

1. Slide off the glass break sensor from the wall mount.
2. Locate the battery compartment on the back panel.
3. Push the release tabs to expose the internal batteries.
4. Remove the battery from the sensor’s compartment.
5. After 30 seconds, reinsert the battery unit into the bed.

Bonus Tip: Insert a New Battery!

The SimpliSafe glass break sensor uses a single CR-123A 3V lithium battery, with a typical life expectancy of up to 2–3 years. 

The battery’s life span heavily depends on how often the sensor goes off, the environmental temperature, and the battery’s construction quality.

Tip: To improve the sensor’s detection, replace the battery once every year!

2. Re-Arm the SimpliSafe System

You can address issues with the SimpliSafe system by disarming and then arming the system again through the SimpliSafe mobile app.

The typical cause for the “Offline” status of the glass break sensor is the active “Disarmed” or “Away” status set within your SimpliSafe application.

Here’s how to re-arm your SimpliSafe system and all of the extra sensors:

1. Verify that your base station’s status lamp is blinking.
2. Next, open the SimpliSafe app on your mobile device.
3. Go to the activity log of the system on the homepage.
4. Tap on the “Disarm” button on the activity status page.
5. Wait for about 5 seconds and press the “Arm” button.

Note: Temporarily deactivating your system’s security will cause all sensors to go offline!

3. Check the Base Station’s Wi-Fi

If the base station has lost Wi-Fi connection with your network, all extra sensors and third-party devices added to your system will be shown “Offline” within the app. 

The SimpliSafe keypad and base station maintain a consistent cellular connection, so you can pair the base station only through the SimpliSafe keypad’s menu.

Here’s how to connect the base station to Wi-Fi:

1. Press the “Menu” button on the SimpliSafe keypad.
2. Next, enter the master PIN to gain menu access.
3. Go to “Settings” and press on the “Wi-Fi” button.
4. Select a 2.4GHz Wi-Fi network from all networks.
5. Enter the Wi-Fi password and press “Connect.”

Alert: Inspect your network equipment if your base station keeps losing connection!

4. Set the System to “Test” Mode

The “Test” mode feature is available with all SimpliSafe keypads and allows the homeowner to individually test each of the assigned extra sensors via noise notification.

So, if the glass break sensor has lost connection with the base station, it will not be detected during the testing mode.

Here’s how to activate the “Test” mode on your SimpliSafe security system:

1. Press the “Menu” button on your SimpliSafe keypad.
2. Enter the Primary PIN to access the keypad settings.
3. Then, tap on “Test” mode and wait for ∼20 seconds.
4. Press the Action button on the glass break sensor.
5. Check if your base station pronounces a notification.

Each extra sensor, including the glass break sensor, has an in-built action button that serves to test out the connection with the base station while the system is in “Test” mode.

If your sensor remains connected, the base station should announce “Glassbreak Sensor” as your indication.

Note: You can exit “Test” mode by pressing “Test” again in the keypad’s menu!

5. Check for Wireless Interference

The SimpliSafe uses standard cellular transmission technology to communicate with each extra sensor so that the signal can be congested easily. 

This is one of the most common reasons why the glass break sensor is “Offline,” so you should check all sources of interference.

Here’s what could potentially interfere with the glass break sensor’s cellular signal:

• Bluetooth devices.
• RF transmitter units.
• Baby phones/radios.
• Reflective surfaces.

Alert: There must be no wireless devices close to the base station or the sensor!

6. Remove the Sensor From the App

In case only the glass break sensor appears as “Offline”, and all other external devices are working correctly with the base station, you should re-add the sensor.

The SimpliSafe app allows for quick and efficient management of all connected devices with a few simple clicks.

Here’s how to remove and re-add the glass break sensor from the SimpliSafe app!

8. Restore the Base Station to Defaults

If the SimpliSafe glass break sensor is still “Offline” in the app, perhaps the sensor’s cellular connection to the base station has been lost.
