Connectivity and compatibility7

Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	ZigbeeZigbee 3.0, 2.4 GHz (specification table on the product page) [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	Hub requiredMaker: it is a Zigbee device and needs a Zigbee hub; it does not connect to a Wi-Fi router directly [2]
Wireless range — what it means The stated radio range, usually in open space. Walls and floors cut it noticeably.	Not stated by the manufacturer
Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Via hub / coordinatorAVATTO lists the ZWS16 among its Zigbee devices for Home Assistant: connection through a Zigbee coordinator (dongle or gateway); the page shows Zigbee2MQTT [5]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	NoThe maker does not claim Matter; the device uses Zigbee 3.0 [1]
App — what it means The maker’s app used to set up and control the device.	Tuya Smart / Smart Life, AVATTOThrough a compatible Tuya Zigbee hub; works with Amazon Alexa and Google Assistant according to the maker [1]
Radio frequencies and transmit power	2.4 GHz [4]

Control and features2

Built-in siren — what it means Whether the sensor has its own audible alarm. A built-in siren is heard near the sensor even without internet or a hub; without one, you are alerted on your phone and, if set up, by the hub’s siren.	YesThe 100 dB alarm is stated only in the short product description on the AVATTO website; the manual and the specification table do not describe a sounder [3]
Siren volume — what it means Volume of the built-in siren as stated by the maker; the distance it was measured at is given in the note. The same decibel figure at 3 m means a louder source than at 1 m; each extra 10 dB sounds roughly twice as loud.	100 dBFrom the short product description; measurement conditions are not stated [3]

Measurement and detection3

Detection method — what it means Probes on the housing trigger when water reaches the sensor itself. A remote probe sits on a wire wherever you need it, and a sensing cable reacts at any point along its length — along a wall or under appliances.	Probes on the housingTwo probes on the underside of the housing ("Sensing probe"); the sensor is placed on the floor in the area to monitor. Probes are nickel-plated copper [4]
Sensing cable connection — what it means Whether a cable that detects water along its whole length can be connected. One sensor then covers a long stretch of floor while the housing stays dry.	Not supportedThe manual's product description shows only the button, the indicator and two probes — there is no connector for an external cable [4]
Minimum water depth to trigger — what it means How much water on the floor is needed for the sensor to trigger. The smaller the value, the sooner it notices a puddle.	Not stated by the manufacturer

Housing and installation4

Ingress protection (IP) — what it means Protection against dust (first digit) and water (second). IP20 is for dry rooms only, IP44 resists splashes, IP65 and up handle water jets and outdoor use.	IP65IP65 is the maker's answer in the FAQ section. An infographic on the product page says IP67; the manual gives no IP rating [2]
Dimensions — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	Ø 59.5 × 17 mm [4]
Weight — what it means The device’s weight without packaging, per the maker.	Not stated by the manufacturer
Mounting — what it means How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.	Screw-fixed (surface)Placed on the floor where a leak may occur [4]

Power4

Battery life — what it means Typical life on one set of batteries or one charge, per the maker. Frequent triggers, cold and a weak signal shorten it.	12 months"More than one year" at 20 triggers per day [4]
Batteries or battery — what it means Which cells it takes and how many. A built-in rechargeable battery is stated in the value.	1 × CR2032 (3 V) [4]
Low battery alert — what it means Whether the device warns in advance that the battery needs replacing — with a short beep, an indicator or an app message. A device with a dead battery no longer warns about carbon monoxide.	Yes [4]
Device power input	3 V ⎓ (CR2032 battery) [4]

Package contents1

Batteries included — what it means Whether batteries come in the box or have to be bought separately.	Yes"Battery Included" in the short product description on the AVATTO website [3]

Operating conditions2

Operating temperature — what it means The air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms.	−10…55 °C [4]
Operating humidity — what it means The rated relative humidity range, non-condensing.	Not stated by the manufacturer

Model and version1

Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	White [1]

Delivery, payment and returns

In your home

First detect it. Then trigger the right routine.

A sensor reports measurements or events. What happens next depends on configuration and separate control devices.

What to check before buying

The sensor alone cannot stop water. We check plumbing, the actuator, power, local communication and manual control. Phone alerts usually need internet.
