Rushing to inspect the devices first thing in the morning, my heart sank realizing the motion sensor was unresponsive.

However, using SimpliSafe’s online tips, I systematically troubleshot issues like low battery, improper positioning near thick walls, and external wireless interference from a new baby monitor.

Within an hour, I got the sensor functioning properly again with strategic relocation – no costly replacement parts required.

In this in-depth troubleshooting guide, I’ll walk you step-by-step through understanding common reasons your SimpliSafe motion sensor may have stopped working, figuring out the likely cause, and resolving the problem so you can get your home security back up and running.

First Things First: What Signs Indicate My SimpliSafe Motion Sensor Not Responding?

Before diving into fixes, let’s cover the main signs that indicate your SimpliSafe motion sensor is having issues:

• You’re not getting notifications when there’s motion, like usual
• Your SimpliSafe base station doesn’t make alarm sounds when it should
• You see error messages like “Sensor Offline” or “Communication Error”
• The motion sensor’s light is flashing red or blue (Gen 1 sensors)
• Sensors randomly go offline or messages say it’s “open”

Lack of notifications and alarms are the biggest red flags. But also note down any odd behavior with lights or error messages – these all give clues to potential causes.

An important thing to check is your SimpliSafe app notification settings. If those are disabled for certain sensors, it would explain why you’re not getting alerts.

So triple check your notification settings match what you expect before assuming your sensor is broken.

Okay, notifications enabled…now what?

Reasons Why Your SimpliSafe Motion Sensor May Stop Responding

Many things can potentially interfere with or disable a motion sensor. But don’t worry – most causes of SimpliSafe motion sensor problems are pretty straightforward to resolve once you know where to look.

Here are the most common culprits behind non-responsive SimpliSafe motion sensors:

1. Dying Battery

Like most wireless electronic devices, SimpliSafe motion sensors are battery powered. If the battery runs down, the sensor will become less reliable or stop working altogether.

• Older Gen 1 SimpliSafe sensors in particular are prone to battery issues since they don’t have a low battery indicator.
• Newer Gen 2 models display battery notifications, but will still eventually stop working as power gets critically low.

Low battery is one of the most frequent reasons SimpliSafe motion sensors stop detecting motion.

Regularly replacing batteries per the manufacturer recommendation prevents problems.

2. Mounting Location & Interference

Where you place the motion sensor plays a huge role in whether it reliably detects motion and connects with the SimpliSafe base station.

Common motion sensor mounting problems include:

• Mounted in very sunny rooms. Direct sunlight can overheat and disrupt the sensor.
• Close to walls, appliances or thick furniture that block wireless signal.
• Too high or too low relative to the area it should cover. This leaves “blind spots”.
• Too far away from the SimpliSafe base station for a reliable connection.

Additionally, wireless devices like Wi-Fi routers, baby monitors, Bluetooth speakers, etc. operating on a similar frequency can create interference if placed too close to the sensor.

Carefully choosing placement is crucial so your SimpliSafe motion sensor has an unobstructed view and strong communication signal.

3. Physical Damage or Dislodging

It’s also possible something physically damaged or dislodged your motion sensor. For example:

• Pet/child/cleaning accident knocking the sensor off the wall
• Electrical surge frying the sensor circuits
• Exposed to liquids or debris clogging components
• Attempted tampering by an intruder

In most cases where physical interference occurs, you’ll get an accompanying error about the sensor being offline or tampered with.

So if you see those warnings, thoroughly inspect the device for any signs of damage.

4. Software & Connectivity Issues

Finally, while less common, glitches in the system software or connectivity can also cause problems:

• SimpliSafe sensor/base station firmware bug
• Wi-Fi network interruption impacting connectivity
• Server-side app notification issues

Rebooting and keeping firmware updated often resolves intermittent software issues. Just make sure your Wi-Fi is working too before assuming sensor hardware failure!

Alright, now that you know the main reasons why SimpliSafe motion sensors potentially stop responding, let’s get to troubleshooting.

Step-By-Step Troubleshooting When Your SimpliSafe Motion Sensor Stops Working

When dealing with a non-responsive SimpliSafe motion sensor, stay calm and tackle troubleshooting methodically.

I like to think of it as eliminating suspects to uncover the culprit!

Here is a step-by-step process:

Step 1: Replace Batteries

Since low battery is the most common cause of SimpliSafe motion sensors failing to respond, always start by replacing batteries.

• For Gen 1 models, unscrew the back panel and insert 2 new CR123A batteries, ensuring correct polarity.
• For Gen 2 models, slide the battery tab to unlock the cover and swap in a new CR2450 battery matching polarity.

Battery replacement is quick and rules out the most likely culprit.

Test your sensor after replacing batteries. If the issue persists, move on to other troubleshooting steps.

Step 2: Inspect Sensor Placement

Next, thoroughly check where you mounted the non-responsive motion sensor:

• Is it positioned correctly to monitor the desired area?
• Is anything obstructing the sensor’s field of view?
• Is it exposed to direct sunlight or radiant heat sources that could overheat it?
• Is it mounted near potential sources of wireless interference like Wi-Fi routers and electronics using similar frequencies?

Carefully inspect from all angles to check for any placement issues or obstructions that could be impacting performance.

Additionally, relocate the sensor temporarily to rule out environmental factors. For example, move it to another room away from sunlight/appliances and test if it suddenly starts working properly.

If you identify placement as the issue, permanently move the sensor to a better location.

Step 3: Rule Out Physical Damage

Thoroughly inspect your non-responsive SimpliSafe motion sensor from all angles looking for any signs of physical damage:

• Cracks, dents or holes in the plastic housing
• Detached or damaged sensor circuit boards
• Debris/liquid inside housing blocking motion detection
• Dislodged/severed power cables (hardwired models)

Refer to the SimpliSafe sensor manual diagrams to understand what the device internals should look like when intact.

If physical damage occurred, the sensor will likely need replacement rather than repair.
