The Hunter NODE-BT-400 brings smartphone control to battery-powered irrigation. Install it in the valve box, pair it over Bluetooth 5.0 (BLE) with the NODE-BT app on iOS 9.0+ or Android 5.0+, and set up your watering from up to 15 m away, with no mains power needed. It manages 4 stations through DC latching solenoids and runs on one or two 9 V alkaline batteries. Programming is generous: 3 programs with 8 start times each, run times from 1 second to 12 hours, seasonal adjustment and a suspend function of up to 99 days for rainy periods. The IP68 submersible housing is made for buried valve boxes, outputs deliver 9–11 VDC and the maximum cable run is 30 m with 1 mm² wire. Optional accessories include the SC-PROBE soil moisture sensor and the SP-NODE-BT solar panel.
