Sonoff Hydro DUO vs Sonoff Hydro ONE Lite

Real-time app alerts for low battery, water shortage (flow under 5 L/min), water leakage (flow detected after the valve closes) and freeze risk, with an option to close the valve automatically on a water shortage.

Real-time app alerts for low battery and freeze risk, the latter triggered when the local minimum temperature drops below a threshold you set. Without a flow meter the Lite cannot raise the water shortage and leakage alarms its Hydro ONE sibling does.

Bluetooth Low Energy powers SONOFF's Proximity mode, which lets a phone control the valve and set schedules directly when there is no Zigbee gateway or the outdoor signal is unstable. Zigbee mode and Proximity mode are used one at a time, not together.

Zigbee 3.0 end device, so it needs a coordinator or gateway to join a network. SONOFF lists the ZBBridge-P, ZBBridge-U, NSPanel Pro and iHost as its own gateways, plus the Dongle Plus MG24, Dongle Lite MG21, Dongle Max and ZBDongle-P/-E for Home Assistant.

Smart scenes trigger on valve state, an irrigation duration reaching a set number of minutes, or the battery dropping below a set level, and act on valve state or a delay. Scene linkage is available on every gateway SONOFF lists, including Alexa and SmartThings.

With the child lock on, the local button is disabled and control is only available through the app.

Daily, monthly and half-yearly charts of watering duration and volume per zone, viewable and downloadable for up to 6 months.

Daily, monthly and half-yearly charts of watering duration, viewable and downloadable. The Lite records duration only, where the Hydro ONE also records volume.

Alexa supports neither the Matter Water Valve device type nor any irrigation category, so the valve has nothing to map to

SONOFF's Matter bridge device list covers the Hydro valves (SWV-NH and SWV-BSP) but states they are supported only in Google Home, because Apple Home does not implement the water valve device type. Apple Home has no Zigbee radio either, so there is no other route.

SONOFF's Hydro series comparison table lists Google Home for the Hydro DUO, reached either through a SONOFF Matter bridge or through eWeLink cloud-to-cloud linking. Google Home is the one Matter platform that renders the water valve device type.

The product page states the valve integrates with ecosystems like Home Assistant or Google Home through a Zigbee gateway or coordinator. SONOFF's bridged device list confirms Google Home is the one Matter platform that renders the water valve device type, reached through a SONOFF Matter bridge or through eWeLink cloud-to-cloud linking.

SONOFF documents the Hydro DUO on Home Assistant through both Zigbee2MQTT and ZHA, listing which features each exposes. ZHA additionally needs the Hydro_DUO_ZHA_Script SONOFF publishes.

SONOFF documents the Hydro ONE Lite on Home Assistant through both Zigbee2MQTT and ZHA, listing which features each exposes. ZHA additionally needs the script SONOFF publishes; without it the valve arrives as a plain on/off entity.

The valve is not a Matter device itself: it is Zigbee 3.0 only. SONOFF lists the Hydro valves (SWV-NH, SWV-BSP) among the models its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) republish to Matter, exposing valve configuration and control plus flow measurement.

SONOFF's compatible Zigbee hubs table for the Hydro DUO lists SmartThings through the Aeotec Smart Home Hub V3 acting as the Zigbee gateway, covering manual irrigation and scene linkage.

SONOFF's compatible Zigbee hubs table for the Hydro ONE Lite lists SmartThings through the AeoTec Smart Home Hub V3 acting as the Zigbee gateway, covering manual irrigation and scene linkage. Owners also report pairing it to an older Samsung V2 hub, where it appears as an on/off switch that schedules drive.

Up to 6 smart schedules per channel, 12 in total, with rain delay, seasonal multipliers per month and weather-based skipping of the next 24 hours.

Six groups of smart schedules, each set by duration, with odd or even days, an interval of 1 to 30 days or specific weekdays. Rain delay skips tasks manually, seasonal adjustment applies a monthly multiplier, and weather-based adjustment skips the next 24 hours on rainfall, humidity or temperature thresholds.

SONOFF rates battery life at about 1 year under normal use, tested at two watering runs per day of 30 minutes each. The valve alerts on low battery and shuts off at a critical charge to avoid runaway watering.

Input is 6V from four 1.5V AA cells, housed in a pull-out compartment with an integrated gasket. There is no mains or USB option.
