💡 Hydro ONE Lite vs Hydro ONE — which do I need? The Hydro ONE (SWV-ZFE) includes a built-in flow meter for volume-based watering and water usage tracking. The Hydro ONE Lite (SWV-ZNE) is the same valve without the flow meter — duration-based watering only, at a lower price. Both have brass inlets, weather skip, seasonal adjustment, and dual Zigbee+BLE communication.

⚠️ Installation notes: Vertical installation is recommended. Not suitable for drinking water — designed for garden irrigation with standard tap water. Do not reverse the inlet and outlet. This is the EU/BSP version (SWV-ZNE) with G3/4-14 thread — standard for South African garden taps.

📡 Don't have a Zigbee hub yet? Pair this with our SONOFF ZBBridge-P or ZBDongle-E. Both stocked at Eiferer. The Hydro ONE Lite also works without a gateway in BLE proximity mode.
