Neo Smart Water Valve NAS-WV02W Setup Guide

Aqara Neo Smart Water Valve NAS-WV02W - Setup Guide

Tools required:

Adjustable spanner or pipe wrench
PTFE (plumber's) tape
Screwdriver (for mounting bracket, if used)
Bucket and cloths (to catch residual water)
6 × AA batteries or the compatible DC 8.4V adapter (sold separately)
Smartphone or tablet (iOS or Android)

Applications required:

Aqara Home app (available on the Apple App Store and Google Play)
Optional: Amazon Alexa, Google Home, or Apple Home app for voice control and cross-platform automations

Before you begin:

Confirm you have an Aqara Zigbee hub already set up and online in the Aqara Home app. The Neo Smart Water Valve requires a compatible Aqara hub for connectivity.
Check that your pipework is DN20 (¾ inch) and that the operating pressure falls within 0.02-1.0 MPa.
Ensure the installation location stays within the 0-55°C operating temperature range and is indoors.
Professional installation by a qualified plumber is recommended when integrating the valve into a mains water supply.

Step 1 - Prepare the valve:

Unbox the valve and check the contents: valve unit, mounting bracket and fixings, and installation guide.
Open the battery compartment and insert 6 × AA batteries, observing correct polarity. Alternatively, connect the DC 8.4V adapter (sold separately).
Power up briefly to confirm the status LED illuminates, then power down again before plumbing installation.

Step 2 - Isolate the water supply:

Turn off the mains water supply at the stopcock.
Open a downstream tap to release residual pressure and drain water from the section of pipe you will be working on.
Place a bucket and cloths beneath the work area.

Step 3 - Install the valve into the pipework:

Fit the valve inline with the pipe run, ensuring the flow arrow on the valve body points in the direction of water flow.
Apply PTFE tape to the male threads and hand-tighten the fittings.
Use an adjustable spanner or pipe wrench to secure the connections. Do not over-tighten - snug plus a small further turn is usually sufficient.
If required, attach the supplied mounting bracket to secure the valve body and reduce strain on the pipework.

Step 4 - Restore water and check for leaks:

Slowly reopen the mains stopcock.
Inspect all joints for leaks. Tighten further or reseal with PTFE tape if any weeping is observed.
Operate the manual override (if applicable) to confirm the valve opens and closes smoothly.

Step 5 - Pair with the Aqara Hub:

Open the Aqara Home app and sign in.
Ensure your Aqara hub is online and select it from the device list.
Tap Add Subdevice (or the + icon) and choose Water Valve Controller from the device categories.
Follow the on-screen prompt to press and hold the pairing button on the valve for approximately 5 seconds, until the LED flashes to indicate pairing mode.
Wait for the app to detect the valve. Assign a name (e.g. Kitchen Water Valve) and a room.

Step 6 - Test remote control:

From the device screen in the Aqara Home app, tap the on/off control to open and close the valve.
Listen for the motor and confirm the water flow starts and stops as expected at a downstream tap.

Step 7 - Configure automations (optional):

In the Aqara Home app, go to Automation and create rules such as scheduled shut-off times or trigger-based closure when a paired Aqara water leak sensor detects moisture.
Set up notifications so you receive alerts on your phone when the valve state changes.

Step 8 - Link to third-party ecosystems (optional):

In the Aqara Home app, open Settings and select Third-party Integrations.
Link your Aqara account to Amazon Alexa, Google Home, or Apple HomeKit as required.
Once linked, use voice commands or cross-platform routines to control the valve.

Maintenance tips:

Check battery level periodically in the Aqara Home app and replace all 6 AA batteries at once when low.
Cycle the valve open and closed occasionally (e.g. monthly) to prevent seizing.
Inspect fittings for leaks at regular intervals.

Note: This product is a low-voltage, battery/DC-powered device and does not involve mains electrical wiring. However, if integrating with any mains-powered accessories or adapters, ensure they are installed in accordance with local electrical regulations.
