Connectivity and compatibility10

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, 2405–2480 MHz [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 requiredNeeds a Zigbee 3.0 hub: SONOFF ZBBridge / ZBBridge-P / ZBBridge-U, NSPanel Pro, iHost, SmartThings Hub V3 or a Zigbee coordinator (ZBDongle-P/-E). Philips, Alexa, IKEA and Fritzbox gateways are not supported [2]
Wireless range — what it means The stated radio range, usually in open space. Walls and floors cut it noticeably.	130 mIn open space [1]
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 / coordinatorVia a Zigbee coordinator: ZHA or Zigbee2MQTT (e.g. SONOFF ZBDongle-P/-E); leak state, history, local scenes, OTA [2]
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.	Via bridge (hub)The sensor is not Matter itself; it reaches Apple Home and other Matter systems through a software Matter bridge (eWeLink CUBE) or a SONOFF hub acting as a bridge [2]
App — what it means The maker’s app used to set up and control the device.	eWeLinkThrough a SONOFF Zigbee hub; status in Alexa, Google Home, SmartThings, Alice and IFTTT [1]
Processor / radio chip — what it means The microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed.	Silicon Labs EFR32MG22 [1]
Radio frequencies and transmit power	2405–2480 MHz [1]
Transmit power — what it means The coordinator's maximum radio output. Higher power gives a steadier link to distant devices, but range in a home depends more on walls and the number of routers in the network.	≤ 10 dBm (EU) [1]
Pairing window	180 sEnter pairing by holding the button for 5 s [1]

Control and features1

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.	NoNo built-in siren: on a leak the sensor triggers the Zigbee hub's sound alarm (through a local scene, even without Wi-Fi) and an app push notification [1]

Measurement and detection5

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 housing, sensing cableGold-plated probes on the sensor housing plus the WLDC200 cable, which attaches to the sensor magnetically and reacts to water along its length [3]
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.	Cable included"Water Leak Sensor & Detection Cable" kit: SNZB-05P sensor + WLDC200 cable. Cables can be chained in series with no limit on total length [4]
Included sensing cable length — what it means Length of the cable in the box. The longer it is, the more floor one sensor covers; on some models cables can be chained.	2 mWLDC200 cable, 2 m; can be extended with more WLDC200 cables [3]
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.	0.5 mmThe raised probes react to liquid from 0.5 mm deep; stated to work on metal surfaces without false alarms [4]
Cable connection	Magnetic connector onto the sensor probes; USB-C plug at the other end for chaining cables in series [3]

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.	IP67For the sensor housing; the product page cites testing to IEC 60529. IP67 is also in the manual [4]
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.	48 × 48 × 21.6 mmWLDC200 magnetic connector: 30 × 30 × 11 mm [1]
Weight — what it means The device’s weight without packaging, per the maker.	34.3 gSensor without battery; the WLDC200 cable adds 32 g [1]
Housing material	PC+ABS [1]

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.	60 months5 years at 50 triggers per day (also in the manual); per the product page, a theoretical value from SONOFF lab tests at 25 °C with a SONOFF hub [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 × CR2477 (3 V) [1]
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.	Not stated by the manufacturer
Device power input	3 V ⎓ (CR2477 battery) [1]

Package contents3

Batteries included — what it means Whether batteries come in the box or have to be bought separately.	YesThe battery is pre-installed: pull out the insulation sheet to power on [1]
Package contents	SNZB-05P sensor, WLDC200 leak detection cable (2 m), 3 cable clips, quick guidesPer the "Water Leak Sensor & Detection Cable" variant image and the WLDC200 package image on the SONOFF site [4]
Cable weight	32 g [3]

Operating conditions3

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…60 °C [1]
Operating humidity — what it means The rated relative humidity range, non-condensing.	0–80%Sensor 0–100% RH; WLDC200 cable 0–80% RH, non-condensing: in very high humidity the cable may raise a false alarm [5]
Operating altitude	up to 5000 m [1]

Model and version2

Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	White [1]
Manufacturer certifications	CE, FCC, ISED, RoHS; EN 62368-1 [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.
