Review on 🌡️ meross Wireless Temperature and Humidity Monitor Sensor: Hub Required, Alerts Thermometer & Hygrometer, IFTTT Support - Ideal for House, Wine Cellar, Living Room, Baby Room, and Pet Monitoring by Darnell Murphy

I ordered a hub and 1 temperature sensor for my fountain, it worked as expected. So I ordered another temperature sensor for outdoor use in a sheltered area (no rain or snow). It worked fine until the temperature dropped to 3 degrees. At that moment he lost contact with the hub. I brought it in and let it run for a few hours and then tried plugging it back into the hub. It won't reconnect now. Just constantly flashing green, I tried resetting everything with the same results. The first temperature sensor still works fine, but the second is useless. Wouldn't buy again, very disappointed, 3 degrees shouldn't bother the sensor all the time.
