The BL-IP is a waterproof, battery-operated, Bluetooth® watering controller, able to sequentially schedule 9V solenoid valves. It is ideal for use with undersoil installations, as it eliminates the need to open manholes! Its water meter input enables you to take action in the event of leaks, or over- or under-consumption. Water consumption graphs reported via the app. The rainfall sensor is used to pause watering if it rains.
