Water Sensor Offline

If your Water Sensor is showing as offline on the SimpliSafe® Mobile App, this is an indicator that the battery within the device needs to be replaced. 

The Water 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, twist the bottom and top apart and replace the battery inside. To close it again, make sure that the grooves are aligned before twisting it shut. 

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, you’ll need to follow the steps below to remove the Water Sensor from your system and then re-add it.
