Smart App Control: When you connect the WiFi sprinkler timer and WiFi hub with 2.4Ghz WiFi, you can remotely control it through the RAINPOINT app anytime, anywhere. No WiFi? You can still connect to Bluetooth from up to 60 meters away. (5Ghz WiFi not supported) Expandable Irrigation System: To cover more areas that need watering, it allows adding multiple WiFi sprinkler timers to your irrigation system. And for system stability, we recommend not adding more than 4 WiFi water timers. Flexible Watering Schedule: Each WiFi hose timer can set multiple different watering schedules to meet your abundant watering needs. You can also choose from two watering modes: normal cycle mode and soaker cycle mode to help you get the most out of every drop and save on your water bill. Rain Delay & Manual Watering: When it rains, you can easily set a delay of 24/48/72 hours on the APP before executing the watering schedule. And when you need temporary watering, you can turn on manual watering with one click without affecting the watering schedule you set
