Nous LZ3 Zigbee Smart Motorized Water / Gas Valve Actuator

Product detailed description

Nous LZ3 Zigbee – Prevent Water Leaks and Gas Emergencies

A bursting pipe or a leaking gas line can cause catastrophic property damage in a matter of minutes. The Nous LZ3 Motorized Smart Valve Actuator (Zigbee protocol) provides an incredibly effective defense mechanism against such disasters. This ingenious device mounts directly over your existing main ball (lever) valve for water or gas. It acts as an external robotic arm, allowing you to physically close and open your main utility lines remotely from your smartphone or instantly through home automation.

Zero Plumbing and No Pipe Cutting

Installing this smart actuator is completely DIY-friendly and requires absolutely no professional plumbing tools. The unit securely clamps directly onto the exterior of the water or gas pipe, directly above the valve. Its strong, adjustable robotic arm then grabs your valve's existing lever handle. When triggered, the electric motor physically turns the lever 90 degrees to shut off the supply. In the event of a power outage, a manual release pull-ring on the clutch mechanism allows you to disengage the gears and turn the valve handle freely by hand.

Life-Saving Automations in the Tuya App

Operating on the robust Zigbee wireless standard, the device links flawlessly to the Nous Smart Home or Tuya apps (a Zigbee Gateway is required). If you are rushing to the airport for a vacation and forgot to shut off the main water line, you can do it with a single tap from your car, or ask Google Assistant/Amazon Alexa to do it for you.

The true power of the LZ3 shines when paired with smart environmental sensors. If you place a smart water leak sensor under your washing machine or boiler and it detects a puddle, it can trigger an emergency automation scene. The smart hub will instantly send a command to the Nous LZ3 actuator to close the main water valve immediately—preventing thousands of euros in flood damage before you even notice there was a leak.

Advanced System Integration (FIBARO & Homey)

Because it utilizes the standardized Zigbee protocol, advanced smart home users can natively integrate this device with professional-grade controllers like the FIBARO Home Center 3 (HC3), which fully supports both triggering and open/closed state reporting. It can also be added to the Homey ecosystem (added as a generic Zigbee device, allowing for actuation, though state reporting back to the app is limited).

Technical Specifications:

• Communication Standard: Zigbee 3.0. Requires a connection to a central Zigbee Gateway (like the Nous E1) or a compatible smart hub.
• Power Supply: Direct mains power via the included 12V/1A DC wall adapter.
• Operation Speed: Fully opening or closing the valve takes approximately 5 to 10 seconds.
• Motor Torque: Powerful 30 - 60 kg.cm geared motor (strong enough to turn stubborn, stiff valve levers).
• Compatibility: Designed exclusively for mounting over standard 90-degree ball valves with flat lever handles.
