Abstract: The present disclosure relates to systems and methods for determining an estimated number of regenerations remaining, an estimated salt remaining, an estimated period between regenerations, an estimated time until salt refill and/or an estimated time until depletion for a water softener system. The estimated period between regenerations may be determined based on water usage data derived from flow rate data generated by a smart flow meter coupled to an output of the water softener system. A processor may send one or more salt refill alerts to one or more electronic devices in response to determining that the time until a salt refill is needed is less than one or more predetermined thresholds.
