Bests & Worsts Reviews from Amazon

This device is easy to use, accurate and convenient. It is however, not built with your security in mind. This is the reason for one star. First, it requires the use of their "Govee Home" app, and only their app. This would be fine if the app provided some semblance of being secure, but it does not. First, it wants to know your location, the app will not start without that "vital" connection. Why? Who knows for sure, but the second requirement is the kicker. Even though this device is a Bluetooth transmitter, THE APP WILL NOT RETRIEVE THE BLUETOOTH TEMPERATURE DATA UNLESS YOU ARE CONNECTED TO THE INTERNET via WiFi or cell data connection! That's right, a BlueTooth-only device - that only transmits temperature and humidity readings, that's it - needs to talk to the internet through your device for some odd reason. This is without signing up for an account on their system, which they want you to do to get the CSV data for a spreadsheet. If you have one of these little gems, you can test this requirement by using a tablet for the app and turning off your WiFi connection for an hour or so, then try refreshing the temperature data. It will give various errors including "Network not available...". Upon turning your WiFi connection back on, refreshing the graph in the app will *instantly* show all the data since you turned it off, up to the minute you turned it on. Yes, BT was on the entire time, and other devices could be seen over that BT while the WiFi was off. So what is it that is so important for the app to do that it needs to talk to the mothership before I can get a temperature reading from my attic, which is all I bought the device for? Thankfully I use this app on a cheap, old factory-wiped tablet with a dummy account, that has no other uses anymore. I suggest that if you, like me, decide to keep this device, and thus are forced to use their app, you should do something similar with an old (factory wiped) phone, etc.
