Did your device get disconnected?
If your power goes out, the supplied 9V battery backup will allow the Monitor to track the water level and audibly sound if it reaches a dangerous level. While on the 9V backup the unit will not connect to Wi-Fi. Because most networks need power, your device will not be able to communicate to the Moen app or voice assistant.
Please check your Wi-Fi router to ensure it is still functioning. You will need to reconnect the device to the network by tapping the “Reconnect” button on your Devices screen. This will send you through the steps to reconnect your Monitor to Wi-Fi. First, you will need to reset the control box. Hold down the button for a few seconds. You should hear one beep immediately and then another one a few seconds later.
