Review on 🚰 HBN Smart WiFi Water Sensor: 2 Pack Leak Alarm for Bathroom, Kitchen, Basement etc. with 75 dB Aloud and APP Alert (Battery Included) by Adolfo Goins

No need for a hub or subscription, but are they trying to trick users into buying a subscription for text and/or phone notifications? I don't like the looks at all. Even if it's a few euros a year at most. At least the app still notifies you why you need it! If you are not at home you will be warned that you have a leak! I give one star for that. Weak signal from the router upstairs to the sensors in the basement. Less than 25 feet measured through the wall and floor. I take one star for that. These are water sensors and most users will need them for potential water leaks. For example, a kettle and a place for a washing machine. My house is only 1125 square feet upstairs and the same size downstairs. A normal size family home, nothing spectacular like Home Alone's home. With such an important device, there should be no weak signals. I take one star for that. Waterproof for water detector. Good idea but almost impossible to open and close properly? It needs to be renewed so that you can open it easily enough and close it securely enough. The drive's smooth, rounded shape was very difficult to open to remove the plastic that prevents the battery from being used during transport and to press the pairing button inside. I take one star for that. This is an important device that people are looking at, not a novelty toy. It's important to be critical of the details surrounding this and I don't see it. It may be a five star product but not as it is now!
