The Resideo L2 Water Sensor and Switch is a great addition to a home or building where water is a concern. It has a stand alone WiFi ability along with the option of dry contacts. This then gives the ability to work with energy or building management systems to give you the ability to alarm on the existing system. Pelican wireless systems in need of water detection can use this in order to alarm the Pelican system.
