Yes, the Sedna5 water damage protection system can also work without an internet connection or smartphone. The system will protect your home as effectively against water damage. The valve will automatically shut off when water is detected, and the water leak detectors will warn you with an audible alarm.

However, if your system is not connected to the Internet and you are not using the Neviweb app on your smartphone or tablet: Sedna5 will not be able to notify you by email or push notification as soon as a leak occurs or if there is a temperature drop. Also, you will not be able to control the opening and closing of the valve through the application remotely.
