SONOFF Zigbee Smart Sprinkler Timer — Hydro DUO 2-Zone, Brass Inlet, IP65 Weather-Adaptive with Flow Meter

This waterproof (IP65) outdoor valve controller powers your garden or yard irrigation with flexible energy options — Type-C or four AA batteries — and connects to a Zigbee 3.0 hub for local smart home integration. It replaces manual timers or basic battery timers to give you volumetric and timed watering, leak and frost alerts, and downloadable usage records so you can manage water consumption and protect plants from over- or under-watering.

How does the Hydro DUO keep my garden watered accurately?

The Hydro DUO offers both timed and volumetric modes so you can water by duration or by exact water volume. A built-in flow meter logs water usage and feeding events so adjustments are based on real consumption data rather than estimates.

• Create up to 6 independent schedules per outlet (12 total) with flexible start times and durations.
• Choose volumetric mode to stop watering when a set liter/gallon amount is reached.
• Download daily, monthly, or six-month flow records to spot trends and optimize irrigation.

What smart features protect my system and save water?

Real-time monitoring watches for battery levels, leaks, low-water conditions and freezing temperatures and sends instant app alerts so you can act before a small issue becomes a major problem. The device can automatically shut off the valve at critical battery or leak events to prevent waste or damage.

• Multi-layer safety: low-battery alerts, leak detection, water shortage and frost warnings.
• Automatic shutoff at critical failure points to avoid runaway watering.
• Child lock to prevent accidental local operation while retaining remote app control.

Will it work with my smart home and how is it powered?

Using Zigbee 3.0, the Hydro DUO integrates with common Zigbee hubs and platforms like Home Assistant for local automations and routines. Power options include a Type-C input for mains or USB power and a backup of four AA batteries for uninterrupted operation during outages.

• Zigbee 3.0 compatibility for local smart home control and automations.
• Works with popular smart home platforms when paired with a Zigbee hub (hub required).
• Dual power: Type-C supply with 4x AA battery backup for reliability.

How durable and easy to install is the Hydro DUO?

The controller features an upgraded brass inlet with an anti-slip design for secure hand-tight connections and long-lasting resistance to outdoor conditions. Rated IP65, it’s designed for external mounting and routine garden use without frequent maintenance.

• Premium brass inlet for sturdy, corrosion-resistant hose and valve connections.
• IP65 enclosure protects electronics from dust and water spray.
• Hand-tighten brass inlet and straightforward wiring for fast installation.
