2026 verdict
Buy the Fibaro Flood Sensor (Z-Wave) when tilt, temperature and a built-in siren matter more than long-range radio.
This water leak sensor also lists freeze alerts, a light, tamper alerts and optional wired power, on a Z-Wave hub, with Home Assistant and SmartThings. The YoLink Water Leak Sensor 1 reaches farther: LoRa to a YoLink hub, IP68, a 5-year AAA rating and a 2-year warranty, but no siren and no temperature sensor. Choose the Fibaro Flood Sensor (Z-Wave) when the hub is Z-Wave and the puck should do more than flash, and the YoLink Water Leak Sensor 1 when the sensor is a building away.

What the differences mean
Siren, tilt, tamper
The Fibaro Flood Sensor (Z-Wave) has a siren, a light, tilt sensing and tamper alerts, plus temperature and freeze alerts. The YoLink Water Leak Sensor 1 has a light only. No siren, no tilt, no tamper and no temperature. One puck replaces several jobs. The other is a long-range water contact.
Radio and seal
The YoLink Water Leak Sensor 1 needs a YoLink hub and uses LoRa, rated in its notes at up to a quarter mile in open air, with an IP68 body. The Fibaro Flood Sensor (Z-Wave) needs a Z-Wave hub. Its weather rating is not documented, so do not treat it as the outdoor one. IP68 is a published YoLink fact. It is not a guess about Fibaro.
Power
The YoLink Water Leak Sensor 1 is rated for 5 years on two AAA cells. The Fibaro Flood Sensor (Z-Wave) is rated for 2 years on a CR123A and can also take optional wired power. The longer battery claim is YoLink. The "plug it in if you want" option is Fibaro.
Platforms and warranty
The Fibaro Flood Sensor (Z-Wave) lists SmartThings and Home Assistant. The YoLink Water Leak Sensor 1 lists Home Assistant and automations, not SmartThings, Apple Home, Google Home or Matter. Warranty is 1 year on the Fibaro and 2 years on the YoLink. Both mark Alexa unsupported on the spec sheet.
Which one to buy if
- your Z-Wave network is already in place and you want a siren plus freeze alerts
The Fibaro Flood Sensor (Z-Wave) lists the siren, temperature, tilt and tamper alerts, with optional wired power.
- the sensor is in an attic, a sump or another building
LoRa and IP68 are why people buy the YoLink Water Leak Sensor 1, on a battery rated for 5 years.
- you refuse to add a separate siren later
The noise is already on the Fibaro Flood Sensor (Z-Wave). The YoLink Water Leak Sensor 1 only lights up.
- you will deploy many pucks off one hub you buy once
That is the YoLink Water Leak Sensor 1 pattern: one hub, then silent IP68 sensors wherever Wi-Fi would drop.

What owners say
Fibaro Flood Sensor (Z-Wave) owners describe a small sensor that pairs quickly on Z-Wave and then pulls double duty, leak plus temperature near pipes, with a sounder and a light on the device. They treat the missing probe and the hub requirement as known limits. YoLink Water Leak Sensor 1 owners talk about range first: attics, sumps and cottages still online, alerts in seconds by app, email and text, and a hub bought once so later pucks stay simple. They also say the sensor is silent unless another YoLink siren is added, and that a drop touching only one electrode may not trip it.
Frequently Asked Questions
Which is better overall: Fibaro Flood Sensor (Z-Wave) or YoLink Water Leak Sensor 1?
The Fibaro Flood Sensor (Z-Wave) when a Z-Wave water leak sensor should also siren, sense tilt and report temperature. The YoLink Water Leak Sensor 1 when range, IP68 and a 5-year battery matter more than a local alarm.
What is the biggest difference between the Fibaro Flood Sensor (Z-Wave) and the YoLink Water Leak Sensor 1?
The Fibaro Flood Sensor (Z-Wave) is a Z-Wave multi-sensor with a siren. The YoLink Water Leak Sensor 1 is a silent LoRa puck that needs a YoLink hub, sealed to IP68 and rated for 5 years on AAA cells.
Does the YoLink Water Leak Sensor 1 include a temperature sensor like the Fibaro Flood Sensor (Z-Wave)?
No. Temperature, freeze alerts, tilt and tamper are listed on the Fibaro Flood Sensor (Z-Wave) and not on the YoLink Water Leak Sensor 1. The YoLink sensor is water only, with a status light.
Which one works without a hub?
Neither. The Fibaro Flood Sensor (Z-Wave) needs a Z-Wave hub. The YoLink Water Leak Sensor 1 needs a YoLink hub, sold separately from the sensor. They are not interchangeable hubs.
Who should buy the Fibaro Flood Sensor (Z-Wave)?
Z-Wave or Home Assistant users who want leak, temperature and tilt in a small sensor that can sound its own alarm.
Who should buy the YoLink Water Leak Sensor 1?
YoLink households covering far or wet locations that can add a siren elsewhere and do not need freeze detection on this puck.
