Smart Water Detector 2 Pack, HBN Wi-Fi Water Leak Sensor Alarm with 75 dB Aloud and APP Alert for Bathroom Kitchen Basement Laundry Room (Battery Included)

Has low wifi range.

I like how it texts over wi-Fi when it senses water. Immediate notification.

It worked with my Wi-Fi

Purchased January 2022. I placed this device next to our oil burner and hot water heater. Tested it and it seemed to work fine. Last night our oil burner leaked water. The device did not alert anyone to the water. This thing is garbage. Do NOT buy. Can’t reach anyone from the company. I want a refund!

Really easy to setup and use. Tested it in a dish by drizzling some water in the bottom of the dish and it notified me immediately.

Product is shipped without any installation information. Support stated the instructions would be found by scrolling thru the Amazon Listing. Even these instructions are sparse.Notifications are not adequate. There is no mention of the need for a SMS subscription even though in the Amazon description, says no subscription. There is a direct to phone (that's running the app) notification that posts at the first alarm but doesn't continue to post if the sensor continues to detect water. Easy to miss notification. The sensor audio alarm is said to be75 dB/1m, but I found it inadequate especially if the sensor is located in a sink cabinet. 1m is about 3 feet so you would need to have your ear next to the cabinet door. It's not even as loud as my clothes dryer 'clothes dried' signal.Overall view is that the hardware is poorly designed plus misleading SMS notification subscription marketing information.
