Why does the Simplisafe Entry Sensor not Responding Error Occur?

A Simplisafe entry sensor not responding error will appear when sensors in the SimpliSafe system fail to check in with the Base Station for more than 24 hours. You must first reset your base station and then wait 45 minutes before reconnecting all of your wired entry sensors to resolve this issue.

Also, if you’re trying to install the SimpliSafe Entry Sensor but getting an error message that says Sensor not responding, it’s possible that your device was configured but never installed.

This can happen if another family member has already placed their entry sensor without deleting the sense your placed first. Please remove the other person’s entry sensor before continuing with your installation if this occurs.

If the entry sensor does not respond, you can clap to confirm whether the sensor is responding or not. This will disclose whether the item has been tampered with in any way and whether it has batteries.

 If the entry sensors do not check in with the Base Station for more than 24 hours, the SimpliSafe system will generate issues.

The Simplisafe entry sensor not responding error can occur due to one of the following reasons :

  • The gadget is currently too far away from your Base Station to communicate.
  • When your system was ordered, the device was programmed but never installed. If you have any extra sensors that are still boxed up and haven’t been installed, make sure to remove them from your Keypad’s “Devices” menu.
  • It is required to replace the device battery or batteries that are causing the issue.

To resolve the Simplisafe entry sensor not responding error, you can try the following troubleshooting methods.

  1. For at least 10 seconds, or until you hear a tone indicating that the sensor has been successfully powered back on, press and hold the reset button on the front of your sensor. If your sensor continues to be unresponsive, the device’s battery will need to be replaced.
  2. Check to see if your Simplisafe security system is running firmware version 3.0 or above. Then unscrew and remove the previous entry point symbol from the location where it was linked, then replace it with the new one on top of your current wiring configuration/shape for more entry points.
  3. Put your base station into test mode to determine if your sensor is too far from the base station by following the basic instructions below.
  • Press the menu on the Keypad, and input your master pin
  • Toggle to Test Mode and select it with the right rocker.
  • When the Base Station enters Test Mode, it will make an announcement.
  • You can now test the sensor by pressing the button on top of it.
  • Assuming the Base Station can communicate with the sensor, it will recognize the test by declaring the sensor’s name (if you used one of the default names offered when setting up your system) and type.
