SOIL-BASED WATERING: When the WiFi irrigation timer is paired with the WiFi soil sensor (not included), it can automatically adjust the watering schedule according to the detected soil moisture, keeping your soil moist but not soggy and avoid overwatering.
VOLUME-BASED WATERING: The 3rd GEN WiFi Watering Timer allows you to water by volume, so you can water as many gallons as you want. For example, when your vegetable patch only needs 8 gallons of water, the timer will only water 8 gallons.
