Review on 🌊 Smart Life WiFi Water Leak Sensor and Alarm: App Notifications, No Hub Required! by Matthew Maxwell

So this cell is powered by a 3V lithium battery, has a main unit with sensors and an additional wired sensor connected to a bracket that provides a secondary flood sensor. This seems to be just what I needed after a small leak under the dishwasher. Anyway connected quickly, but immediately shows low battery level, went out, took a new lithium battery. Should check with a multimeter first, the existing battery was a good 3.0 volts, the new battery was 3.0 volts, so I then try to check the WiFi connection and repeatedly couldn't find it, was 10 meters from the router, delete, reset, etc. after about an hour, decision to return, maybe I just received a faulty item, the instructions are quite easy, thanks
