This article is about the All-New SimpliSafe system. If you purchased a system in 2017 or earlier, you have the Original SimpliSafe. If you're not certain which system you have, you can tell the difference here.
If you are consistently seeing a warning that one of your Entry Sensors is open, despite all of your doors and windows being closed, one of the following items is likely the cause:
- Your Entry Sensor is too far away from its corresponding magnet piece.
- Your Entry Sensor (or its corresponding magnet) is placed on a metallic surface.
First, double check that the printed sensor number matches with the number reported in the warning. If the warning only shows a name, you can access the individual sensor's settings through the keypad to find the sensor number. Next, make sure that all of your doors and windows are closed. If the door/window where this issue is occurring is metal, placing a buffer between the magnet and the metallic surface may help (such as a couple of extra adhesive strips).
If this does not resolve your issue, please contact our customer support team directly for further assistance.
