Entry Sensor Battery Life Expectancy
We installed a SS system late summer 2020 (less than 3 years ago). We have already received several "entry sensor offline" alerts, which seems to indicate the need for a battery replacement. Some of the sensors have come back online and been fine... but I worry they will lose connection again when we are away.
SS literature seems to indicate expected battery life should be up to 5 or 10 years depending on where I look. Is it normal to see these issues after less than 3 years? Should I preemptively replace all sensor batteries?
