Flume 2 Smart Water Monitor vs YoLink Water Leak Sensor 1

The YoLink Water Leak Sensor 1 wins overall, with a lower price, a higher owner rating, and a status LED that flags a leak without needing to check the app. The Flume 2 Smart Water Monitor still wins on connectivity and integrations, reaching Alexa, Google Home and Home Assistant against the YoLink's Alexa and Home Assistant.

Coverage area. The YoLink Water Leak Sensor 1 is a point sensor that only detects water touching its own electrodes, wherever it is placed. The Flume 2 Smart Water Monitor instead reads the home's main water meter, so it catches any leak on the property, not just at the spot where a sensor happens to sit.

Yes, both do. The YoLink Water Leak Sensor 1 communicates over YoLink's proprietary LoRa radio and needs a YoLink hub, sold separately, to reach the app and any integrations. The Flume 2 Smart Water Monitor needs its own included Wi-Fi bridge to relay readings from the meter sensor.

Neither has an audible on-device alarm. The YoLink Water Leak Sensor 1 does include a multi-color status LED for a visual local alert, something the Flume 2 Smart Water Monitor's sensor lacks, but both rely on the app or a connected hub for actual notifications; the YoLink can add a separate YoLink siren for sound.

Buy it if you want an affordable point sensor with long LoRa range from the hub, years of battery life, and a visual status light, and are fine adding several units to cover multiple fixtures.

Choose it if you would rather monitor the entire property's water use from one device on the meter than place individual sensors at every fixture, especially for catching leaks like a running toilet or a buried irrigation line.
