Key Features & Benefits:

• Heavy-Duty Brass Water Inlet:

  Upgraded with a rugged, machined brass inlet to withstand continuous outdoor water pressure (up to 0.8 MPa), heavy direct sunlight, and physical strain.

• Smart Irrigation & Custom Schedules:

  Configure up to 6 flexible watering plans, including duration cycles, specific days of the week, odd/even day schedules, or custom intervals (1–30 days).

• Precise Volume & Flow Tracking (Hydro ONE SWV-ZFE Only):

  Built-in high-precision water flow meter monitors exact litres dispensed. Set watering limits by target volume (capacity mode) to prevent overwatering and view historical consumption trends over days, months, or half-year intervals.

• Dual Wireless Connectivity (Zigbee 3.0 + BLE Proximity Mode):

  Connect over Zigbee 3.0 for remote whole-home automations. When outside Zigbee coordinator coverage, manage watering plans and direct valve control nearby using local Bluetooth proximity mode.

• Smart Safety Protection & Child Lock:

  Physical button lockout prevents accidental triggers from pets or children. The valve includes a fail-safe auto-close timeout and low-battery warning to ensure the valve never sticks open.

• Long-Lasting Battery Operation:

  Powered by 4× standard AA batteries providing long operational life across the watering season without tangled power cords or outdoor electrical outlets.
