Q1: Why does my SimpliSafe door sensor show low battery immediately after putting in a new one?
A1: The base station does not ping sensors continuously. It relies on passive polling loops that can take 12 to 24 hours to clear old alerts from system memory. You can force an instant refresh by entering and exiting System Test Mode through your Keypad.
Q2: Can I use CR2025 coin cells instead of CR2032 in the Gen 3 Entry Sensor?
A2: No. While both offer a 3V nominal output and have matching 20mm diameters, the CR2025 is only 2.5mm thick compared to the 3.2mm CR2032. It will fit loosely inside the housing, losing contact connection and generating intermittent power drops and offline warnings.
Q3: How do I know if the sensor itself is completely dead?
A3: Remove the sensor from its bracket and open the door or tap the pairing button. If the small blue indicator light on the face of the sensor fails to flash even after installing an alcohol-cleaned, verified 3V+ CR2032 cell, the internal circuit board has failed and requires replacement.
