It felt like a bespoke, targeted solution engineered solely for reliability over distance.
My Testing Experience
I placed these silent sensors directly beneath water lines that had caused me grief before, particularly the hard-to-reach area under the guest bathroom sink. Even though the sensors themselves are silent, the Hub instantly relaying the alert via the app proved incredibly effective, functioning perfectly even after I deliberately disabled my main home Wi-Fi extender. I also tried triggering a YoLink siren (purchased separately) locally through the D2D feature, and the immediate response during the simulated internet outage confirmed its robust failsafe capability.
The Honest Truth
The main drawback for some users might be the “silent” design of the sensors themselves; if your internet or power goes out (and you don’t have a siren accessory), you won’t get a local alarm, relying solely on the Hub’s internal redundancy features. You definitely need the Hub working properly for this system to shine.
Quick Specs

My Testing Experience
I placed the base station centrally and dispersed the sensors. The system’s detection sensitivity was impressive; I used a tiny medicine dropper to simulate a leak, and the sensor reacted reliably to water just 0.4 mm deep. I particularly liked the App feature that allows me to temporarily mute alerts (for 10 minutes, 30 minutes, etc.) while I’m actively cleaning up a mess—a thoughtful feature often overlooked by competitors.
The Honest Truth
The major constraint here is that the system requires the included base station and only works on 2.4 GHz Wi-Fi, meaning it’s not truly an independent sensor. Furthermore, while the sensor itself is slim, the base station must be plugged in and connected, creating an additional point of potential failure compared to entirely battery-powered systems.
Quick Specs
Connectivity: 2.4 GHz Wi-Fi (via Base Station), Sensitivity: Senses water at 0.4 mm depth, Alarm: 100 dB (Base Station), Design: Ultra-Slim Sensor (0.7 in), App
Who It’s For
This is ideal for homeowners who live in tighter, modern spaces and need low-profile sensors that can squeeze into extremely confined locations. If you value discretion and high sensitivity to minor moisture, this is your choice.
