A device for monitoring the level or amount of a material within a container is provided. The device includes a detection mechanism that can be a direct detection mechanism or an indirect detection mechanism. When the detection mechanism senses an upper level of the substance in the container that is below a predetermined lower limit for the substance, the mechanism operates an alarm mechanism to emit an alarm to alert an individual to the low level of the substance within the container. The alarm can wirelessly communicate a salt level state to a wireless network or a device on a wireless network that can transmit the status through the Internet to any remote location. In one aspect, the alarm can be sent on a mesh network with a device that can transmit the status and other conditions through the Internet and to an application executing on a mobile device.
