Hunter NODEBT100 Single-Station Bluetooth Battery Controller With DC-Latching Solenoid Avoid the valve box with the battery-operated NODE-BT controller! NODE-BT is enabled with powerful wireless Bluetooth® technology that can be easily managed from a smartphone. Install the waterproof NODE-BT in gardens, parks, medians, roundabouts, greenhouses, or other outdoor applications where AC power is unavailable. NODE-BT is controlled by a multi-language smartphone app. The app maps controllers by location, sends battery-change reminders, and logs controller events for quicker diagnostics. Run-time flexibility is perfect for germinating seeds or other agricultural applications. Best of all, NODE-BT makes battery-powered irrigation convenient and comfortable. For versatility during installation, the controller is mountable in five unique ways. Total app control removes the task of opening dirty valve boxes and programming irrigation schedules on a dark screen. Professionals can also enable irrigation and check battery status right on the controller with the touch of a button, greatly speeding up maintenance.
