【Smart Voice Control】 The Smart WiFi Timer is compatible with Alexa and Google Assistant, so when you're too busy with other tasks to operate your phone, you can turn the watering timer on or off with a simple voice command. Enjoy the convenience of controlling your watering system with your voice 【APP Remote Control】Use the Smart Life APP to add the WiFi Water Timer to your WiFi hub (2.4 GHz WiFi only) so you can create watering schedules anytime, anywhere. The WiFi Sprinkle Timer connects to the gateway via RFID technology and supports longer distances (up to 196 ft.), providing a more stable signal than a Bluetooth connection. So you can travel with confidence! Note: Not compatible with tablets. 【Bluetooth Control Function】 In addition to being controlled by the WiFi hub, the WiFi watering timer can also be controlled by the Smart Life APP via Bluetooth. Even if there is a power outage at home and the WiFi hub does not work, you can still set and manage the watering program on the APP via Bluetooth. The maximum working range of Bluetooth is 49.2 feet in an open area without obstacles 【Two Irrigation Modes】The Outdoor Sprinkle Timer has a timed irrigation mode and a regular irrigation mode. The two different irrigation modes allow you to set different watering times and frequencies, and you can set up to 20 different irrigation schedules and adjust them as often as you like (please make sure that the distance between the router and the WiFi hub, and between the WiFi hub and the timer is between 3 and 10 meters, and make sure that the water faucet is always on) 【Rain Delay & Manual Watering】 This WiFi hose timer features a rain delay that can be set to go 24, 48, or 72 hours without watering, as well as a manual mode for more flexible watering schedules 【Expand Irrigation System】 With just one WiFi hub, you can expand up to 32 WiFi timers to build a smart irrigation system for your garden. In addition, you can add family members to the app to share home irrigation management 【Note】Smart Sprinkler Timer can only connect with 2.4GHz WiFi. If your router is a dual-band router, please enable the 2.4GHz WiFi band separately and name it differently from the 5GHz WiFi band
