Product description: Tuya - flood sensor - ZigBee - Android/iOS application - RTX ZWS3
The Tuya RTX ZWS3 is a wireless flood sensor equipped with a probe mounted on a cable. The device was designed to detect the presence of water and prevent the effects of flooding . The sensor communicates using the ZigBee 3.0 IEEE 802.15.4 standard and works with the Tuya/Smart Life system via a compatible ZigBee gateway . Once flooding is detected, the event can be used to immediately send a notification or trigger a pre-defined automation, such as stopping a washing machine or dishwasher in an emergency. The sensor is powered by two AA batteries , and its low energy consumption extends its lifespan up to 24 months . This means the sensor is not dependent on constant power, improving both comfort and convenience of use, as well as providing a high level of security. The device is compatible with Google Home and Alexa voice assistants.
Attention!
For proper operation, the device requires connection to a ZigBee gateway , which must be purchased separately.

The sensor allows the flood detection probe to be placed directly in a location particularly susceptible to leakage, leaving the rest of the device above the water surface.
Special features of the Tuya RTX ZWS3 sensor
- Detecting the presence of water using a probe: the flood detection probe can be placed directly in a place particularly prone to leakage
- ZigBee 3.0 communication: energy-saving and stable wireless communication compliant with the IEEE 802.15.4 standard, designed for use in smart home systems
- Notifications and alerts: receive immediate event information via the app and transmit the signal to a compatible ZigBee gateway
- Automations: Ability to create automations that link the sensor to other devices in the Tuya ecosystem
- Battery powered: self-contained installation without the need for a wired power supply
- Long operating time: a combination of energy-saving ZigBee communication and power supply with two AA batteries extends the device's operating time up to 24 months
- Integration: the sensor acts as one of the elements of the home security system thanks to its wide compatibility with other Smart Home devices
- Easy installation: the sensor can be mounted non-invasively using double-sided 3M tape
- ZigBee gateway: communication with the Tuya / Smart Life application via the necessary ZigBee compatible central unit
Immediate detection of dangerous situations
The RTX ZWS3 sensor is designed to quickly detect the presence of water in areas particularly susceptible to leaks. Upon contact with water, the device can transmit information about the event to the Tuya/Smart Life system via a ZigBee gateway, enabling the initiation of a pre-configured notification or automation scenario. This allows for a faster response and mitigation of the effects of flooding, for example, near washing machines, dishwashers, boilers, pipes, or plumbing.
ZigBee technology
ZigBee is an advanced, open radio communication standard that guarantees fast, stable, and secure operation . Thanks to its mesh topology, communication between devices is reliable, and failure of a single component does not affect the operation of the entire system. Low power consumption allows devices to operate for long periods on a single battery. ZigBee 3.0 was designed specifically for smart home systems, ensuring broad compatibility and easy integration of new devices.
Smart home with the Tuya Smart app
The Tuya Smart app allows you to manage over 11,000 different devices across 30 categories, such as control, air conditioning, and monitoring. Integration with the ZigBee Alliance provides extensive system expansion capabilities. The app is free and available for both Android and iOS , allowing you to monitor the security of your property from anywhere in the world.
