Frequently Asked Questions

Q: Does this ZigBee water sensor work without a hub?

A: No, the ZigBee 3.0 water leak sensor requires a compatible ZigBee 3.0 hub or gateway to connect to your Wi-Fi network and send alerts to your smartphone via the Smart Life or Tuya app. The hub is sold separately.

Q: How quickly does the flood detector send an alert to my phone?

A: The sensor sends an alarm notification to your gateway and mobile phone almost instantly — as soon as standing water reaches the probe poles (water depth of approximately 0.01 m or more).

Q: How long does the battery last in this water leak detector?

A: The sensor uses a single CR2032 battery (included) and is engineered for up to 1 year of battery life under normal use (based on approximately 20 alerts per day). You'll also receive a low-battery notification in the app when it's time to replace the battery.

Q: Is this water sensor compatible with Alexa or Google Home?

A: The sensor works natively with the Smart Life and Tuya app ecosystems. Compatibility with Alexa or Google Home for voice alerts depends on whether your ZigBee hub supports those integrations. Many Tuya-compatible hubs do support Alexa and Google Home.

Q: Where are the best places to install the ZigBee flood sensor?

A: Common installation spots include under kitchen and bathroom sinks, near washing machines and dishwashers, beside water heaters, in basements, and under refrigerators with ice makers. Any location where a water leak could go undetected is a great candidate.
