WallyHome is a complete home sensing solution that detects and notifies you of water leaks, changes in temperature and humidity, as well as when doors and window open or close. A leak is detected when water touches the contacts of the sensor, which are placed on the bottom. In the event of a water leak, abnormal reading of temperature or humidity, or if a door or window is opened or closed, Wally will send you a notification over Email, Push, and/or Text Message, alerting you to the affected area of your home.
