Key differences between Heiman Smart Water Leakage Sensor and YoLink Water Leak Sensor 1
A summary of selected recorded differences between these water leak sensors. Check the full specification table below for details and conditions.
Feature differences among your selected devices
- Freeze Temperature Alerts (alerts): Heiman Smart Water Leakage Sensor — Yes (Alarm when the temperature drops to 0-3°C (32-37.4°F)); YoLink Water Leak Sensor 1 — No.
- On Device Alert Sound (features): Heiman Smart Water Leakage Sensor — Yes (75 dB); YoLink Water Leak Sensor 1 — No (Silent sensor, a SpeakerHub or YoLink siren adds audible alerts).
Specifications to check side by side
- Other (connectivity): Heiman Smart Water Leakage Sensor — 915 MHz RF (Heiman Gateway required) (The sensor talks to the Heiman Gateway over RF (up to 200 m in open space); the gateway is what connects to Wi-Fi and the app); YoLink Water Leak Sensor 1 — LoRa (YoLink hub required).
- Battery Life (power): Heiman Smart Water Leakage Sensor — 10 years; YoLink Water Leak Sensor 1 — 5 years.
- Battery Type (power): Heiman Smart Water Leakage Sensor — CR123A; YoLink Water Leak Sensor 1 — 2x AAA.
- Temperature (sensors): Heiman Smart Water Leakage Sensor — Low Temperatures (Triggers the freeze alarm when the temperature drops to 0-3°C (32-37.4°F)); YoLink Water Leak Sensor 1 — No.
Information still to confirm
- 3 of 28 comparison fields lack a resolved value for at least one selected device. Missing information is not evidence that a feature is absent.
- Check the full table and manufacturer documentation before ruling out a device.
These observations are derived from recorded catalog data and have not all been independently verified. Confirm details with the manufacturer before purchasing.
Compare capabilities, compatibility and setup requirements.
