- Automatic irrigation for potted plants: waters regularly and quantitatively, so you dont have to worry about unmanned irrigation when you are on vacation or away from home. - APP remote control: timer lets you remotely set multiple automatic watering schedules via the app anytime. Days interval 1-7; Time frequency 0-23 hours and 0-59 minutes. - Two power supply modes: powered by 4 AA batteries or USB. When USB is connected, USB power is used; if the USB power is disconnected, battery power activates. - Efficient water saving: delivers water directly to the root zone, minimizing runoff and evaporation. Up to 70 percent water savings versus traditional watering methods. - Practical use scenarios: keep plants healthy during long trips by configuring schedules in the app; manage a group of potted plants in a living room or balcony with coordinated watering; set up in an office or apartment to maintain plants with limited daily access to water.
