Frequently Asked Questions

How do I install the water timer on a faucet?

Wrap the supplied sealing tape around the faucet threads, then screw on the water timer. Tighten it by hand only; do not use tools.

How do I put the water timer into pairing mode?

Press and hold any button on the water timer for at least 5 seconds until the indicator starts flashing.

Pairing failed: unable to connect to the router?

Tuya Wi-Fi devices generally work best on 2.4 GHz networks. We recommend:

• Use a dedicated 2.4 GHz SSID and do not give it the same name as the 5 GHz network.
• Set the wireless channel to 1, 6, or 11.
• Set the channel width to 20 MHz.
• Use WPA2-PSK encryption and avoid WPA3 mixed mode.
• Test the device close to the router. If the connection becomes stable, weak signal or interference at the installation site is likely the cause.

How can I extend battery life?

In the water timer panel settings, enable Sleep Mode.

How can I stop watering on rainy days?

In the water timer panel settings, enable Skip Rainy Days. You can also enable Rain Delay on the panel home screen.

What water pressure does the timer support?

The WWT802 works between 0.05 and 0.8 MPa (7.25 to 116 PSI). If your line pressure exceeds 0.8 MPa, install a pressure reducer before the timer — over-pressure is the most common cause of leaking thread connections.

Can I leave the timer outside in winter?

The unit is designed for outdoor use, but water left inside the valve can freeze and crack the housing. Before the first frost, remove the timer from the faucet, drain it, take the batteries out and store it indoors.

Do you supply OEM and private-label orders?

Yes. We produce private-label versions of the WWT802, WWT803 and WWT804 for distributors and garden brands — custom logo, packaging, model numbering and app brand skin included. Send your target quantity and market through the quotation form and we will confirm MOQ and lead time.

Which certifications come with the product?

CE-RED, FCC, REACH, RoHS and WEEE. Test reports and declarations of conformity are available for your market entry file on request.

Where can I download the manual?

The WWT802 manual is available in English, German, French, Spanish and Chinese on the manuals page.
