Two-pack water leak sensors

This Emerson TK-WA161 two-pack provides WiFi water leak detectors for home use. Each unit connects directly to a 2.4GHz network and sends instant alerts through the Tuya Smart App. They are suited for homeowners wanting early warning in kitchens, bathrooms, basements or near appliances without a hub or subscription.

Bluetooth-guided setup with six probes

Pairing is handled through the Tuya App using Bluetooth guidance, so no tools are required. The sensors feature two top drip probes and four bottom flood probes for six-point detection. A common issue is that the device only supports 2.4GHz WiFi and will not connect to 5GHz bands, plus it does not integrate with Alexa or Google Home.

120dB adjustable alarm and two-year battery life

Each detector runs on two included AAA batteries rated for up to two years of monitoring, with low-battery alerts sent to the app. The 120dB siren is adjustable for local notification. Buyers who need smart-home voice integration or 5GHz WiFi compatibility should look elsewhere, as this model lacks both.

Questions about this item

How do I confirm the 120dB alarm and app push alerts are active after pairing?

After pairing via the Tuya Smart app, use the app's test function to trigger the siren and verify the notification arrives on your phone; the device also sounds locally when moisture touches the six probes.

What is included in the 2-pack box and are batteries supplied?

The box contains two water leak detectors; each unit comes with two AAA batteries pre-installed so no separate purchase is needed.

Should I choose the 2-pack or buy single units for kitchen, basement and laundry?

The 2-pack covers two zones; add another 2-pack if you need protection in three or more locations such as kitchen, basement and laundry.
