the honest rundown
ok so what does this little puck actually do?
It catches water leaks the second they start — not three hours later when you step in a puddle and ruin your socks. Metal contacts on the base detect water instantly, and if temps drop below 4°C it'll flag that too, so your pipes don't become an expensive ice sculpture. The built-in 75dB buzzer goes off immediately — no HomeBase needed for the local alarm, though you'll want one for push notifications to your phone. Plus it comes with a 1.2m extension cable with a probe thinner than a pencil, perfect for sliding under the washing machine or behind the dishwasher. Five-year battery. Set it and genuinely forget about it until it saves you thousands in water damage 💧
capabilities
What it can do
six reasons this sensor earns its spot on the laundry floor 🎯
Instant Water Detection
Metal contacts on the base detect water the moment it makes contact. No waiting around, no "hmm is that damp?" — it knows, and it'll tell you. Alarm triggers within seconds so you can act before the damage spreads.
contact-based sensingFreeze Alert Below 4°C
Temperature drops below 4°C (39.2°F)? It'll let you know before your pipes do. With ±1°C precision and an operating range down to -10°C, it keeps monitoring even when things get properly cold.
±1°C accuracy75dB Built-in Buzzer
No HomeBase needed for the local alarm — the sensor has its own 75dB buzzer that'll wake up the house. Alarm can trigger up to once per minute so it keeps reminding you until you deal with it.
standalone siren1.2m Extension Probe
The included 3.9ft cable has a slim probe under 0.5cm thick. Slide it under washing machines, behind dishwashers, into crawl spaces — anywhere the puck itself can't reach. Detection where you actually need it.

extension probe
The bit that slides where you can't
Most leaks don't happen in convenient, easy-to-see places. They happen behind the washing machine, under the dishwasher, tucked in that gap between the hot water system and the wall. That's what the 1.2m extension cable is for. The probe tip is under 0.5cm — thin enough to thread into spots you haven't looked at since you moved in.
🧺
Behind the Washing Machine
Where hose connections love to slowly drip for weeks before anyone notices. The probe sits right at the source.
🍽️
Under the Dishwasher
That tiny gap between appliance and floor? The probe's slim design was basically made for it.
🚰
Near the Hot Water System
Ageing valves and pressure relief overflows. Put the probe where the first drip would land.
the real comparison
Flood Sensor vs. finding out 3 hours later
one of these costs $40-ish. the other costs thousands. 🤔

Quick Start Guide
you'll be set up in 5 minutes
Heads up — you'll need a eufy HomeBase
The sensor's built-in buzzer works standalone, but for push notifications, remote monitoring and smart home integration, it needs to connect to a eufy HomeBase (Mini, 2, 3, or Pro). If you've already got one from a eufy camera setup, you're good to go. If not, you'll want to grab one.
