Acid-dispensing system for pools

Abstract

Examples described herein include systems and methods for improved acid-dispensing for pools. An example method can include drawing electrical current at the device through a low-power data channel to charge a battery. The example method can also include receiving at the device, through the data channel, a digital signal instructing the device to dispense acid. The digital signal can include an indication of an amount of acid to be dispensed by the acid-dispensing device. The acid-dispensing device can authenticate the digital signal and discharge acid based on the signal. For example, discharging acid can be performed by powering a pump using energy stored in the battery of the device. In some examples, the acid-dispensing device can confirm water flow to the pool before discharging acid.
