As long as your device has registered Bluetooth connections with sprinkler irrigation, the hose timer will automatically connect to your device via Bluetooth, allowing your watering schedule to continue uninterrupted. When rain mode is on, previously set timing and spray schedules will not work if the weather in which the water timer is rainy. The water timer can be used to water gardening, pots, lawns, patios, flower beds and greenhouses/hydroponics. Not only the irrigation history can be recorded, but this irrigator also has two modes: timed irrigation and cyclic irrigation. Circulation irrigation can set irrigation time and soaking time within a period of time. When rain mode is enabled, previously set timing and spray programs will not run if the weather the sprinkler timer is in is rainy.
