Motion Sensor Gen 2 Offline
If your Motion Sensor Gen 2 is showing as offline on the SimpliSafe® Mobile App, this is an indicator that the battery within the device needs to be replaced.
The Motion Sensor Gen 2 takes a single (1) CR-123A Lithium 3V battery and has a life expectancy of up to 4 years depending on placement and usage.
To replace the battery, slide the sensor up and off its’ bracket. Then replace the lithium battery and slide the sensor back onto its’ bracket.
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, there are two steps you can take to remove the error from the SimpliSafe® App.
First, place your system into Test Mode and test the sensor to reestablish a connection.
To place your system into Test Mode:
Using your Keypad go to Menu > Enter your Primary PIN > Test Mode
Press and release the button on the Motion Sensor. The Base Station should announce “Motion Sensor” and the timeline on the SimpliSafe® App should show “Motion Sensor Test”.
If the Test Mode step does not work, it’s possible that your sensor has been offline for too long. The best step would be to remove the sensor from the SimpliSafe® App and then add it back to your system.
To remove your Motion Sensor Gen 2:
Open the SimpliSafe® mobile app on your phone or tablet
Choose My System from the bottom navigation bar
Select Device Settings
Tap on the sensor you wish to remove
Choose ‘Remove Device’
Once you have removed your sensor, you can add it back using our Installation Guide.
