SONOFF Hydro DUO is a dual-channel Zigbee 3.0 and Bluetooth 5 LE smart water valve with up to 12 customized watering schedules, a flow meter, and alerts for frost risk, leakage, low battery, and water shortages.
Paisit previously reviewed the SONOFF SWV smart water valve, but the company has now launched the Hydro series with various improvements, including a brass inlet instead of a plastic one, weather-based skipping, real-time alerts, and dual Zigbee + BLE so it can work even without a Zigbee gateway. The single-channel Hydro models were introduced earlier this year, and now the Hydro DUO offers a variant with two outlets to manage two watering zones.
