Water Leak Sensor 4 with 105dB Audio Alarm 3-Pack, SMS/Text, Email & Push Notifications, Freeze Warning, LoRa Up to 1/4 Mile Open-Air Range, w/Alexa, IFTTT, Hub Required!

Excellent range, excellent battery life, and the on-device siren is a great addition. I don't think anything beats the Yolink ecosystem for ease of use, app user friendliness, battery life, and range.

I installed these water leak sensors in key spots: under the dishwasher, laundry washer, and next to the water tank, to catch leaks before they become problems. Setup with the hub was smooth. A smart layer of protection for any home.

This system works great.

The water sensor work well, easy enough to setup, both the physical product and app. Highly recommended. When submitting the phone number for sms warning, it took several trys over couple of weeks to be able to submit the phone number, seems like the servers have limited capacity, but have not had a chance to test if it works or not. Overall, the sensor and the app work well.
