Is HomeBase necessary to receive notifications?

Yes. The sensor uses efficient Sub-1G communication with HomeBase to maximize battery life.

Can we customize the temperature that triggers a notification?

No. The sensor is designed to detect when the temperature drops below freezing temperature only.

What is the maximum operating distance from the sensor to HomeBase?

The maximum operating distance is 200 meters.

What is included in the box?

The box contains 1 Quick Start Guide (QSG), 1 Water Sensor, and 1 CR123 Battery.

Does Water and Freeze Sensor have a built-in alarm?

No, the sensor itself does not emit an alarm. Alerts are sent to the HomeBase S380 or S280, where the alarm sound can be customized via our app for distinctiveness from other devices.
