Entry Sensor Offline
Updated
If your Entry Sensor is showing as offline on the SimpliSafe® Mobile App, this could be an indicator that the battery within the device needs to be replaced.
The Entry Sensor takes one Duracell CR-2032 Lithium 3V battery and has a life expectancy of up to 5 years depending on placement and usage.
To replace the battery, slide the sensor off the bracket towards the pairing button. Then replace the lithium battery and slide the sensor back onto its bracket. If your Entry Sensor has a cover over the battery, you’ll need to remove that first. You can refer to our Help Center article for further instructions.
Please note that the error may take up to 24 hours to clear from the SimpliSafe® Mobile App after taking these steps, as the Base Station needs to check back in with the sensor. If you want to bypass that timeframe, you'll need to follow the steps below to remove the sensor and re-add it to your system.
