A watering control system includes a bridge device and a flow control device. The bridge device communicates with a web server to maintain a watering schedule. The bridge device also communicates wirelessly with the flow control device. The flow control device includes an annular inlet for connecting to an external faucet or another source of fluid, an annular outlet for connecting to a hose or another water conveying channel, and a conduit positioned in communication with the inlet and the outlet. The flow control device further includes a wireless receiver and a valve. The receiver is configured to receive a wirelessly transmitted valve activation signal from the bridge device and the valve is configured to open in accordance with the activation signal to enable the fluid to flow through the conduit.
