Review on 🌡️ Govee WiFi Hygrometer Thermometer: Wireless Sensor with App Alerts for Greenhouse, Basement, Pets, and More! by Lakeisha White

I have used two of these in my freezers so we know if the power has gone out for an extended period while we have been away or if someone has forgotten to close the freezer fully. They work great in the freezer, are easy to set up and measure temperature accurately. The only two downsides are (1) I was hoping to put them both on the same WiFi hub (I can connect additional Govee water sensors to the same hub) and (2) I thought the range to send an alert was at least -20 . Although the readings can be so low, the range setting only gets to -4, so they're always outside the low range on our freezers at -10. Please update the lower range or just let the user set 1 upper or lower limit!
