Review on Govee WiFi Hygrometer Thermometer 3 Pack H5151: Indoor/Outdoor Smart Sensor for Room Temperature & Humidity, Wireless with App Alert - Ideal for Home and Greenhouse (not support 5G WiFi) by Alonzo Weaver

I am very happy with this purchase. It works as I expected. I've bought other WI-FI temperature monitors in the past that I couldn't set up, had connectivity issues, or had other usability issues. Since your WI-FI router is configured for a low-frequency network (2.4 GHz), installation is quite easy. (If you don't see/know your 2.4GHz network, whoever set up your router should set it up first.) The temperatures appear to be accurate, being within 0.1 of each other. 2 minor complaints: 1) I would like a cleaner display for connected sensors, both in the widget and especially in the app, they take up too much screen space and scrolling. Being happy with it I ordered 6 more sensors but the app doesn't allow to see them all at once, you have to scroll to see more than 2 sensors at the same time. 2) The widget seems to only allow you to view 3 sensors, you can choose which 3. Otherwise, it's easy to view status and adjust settings. You can specify a temperature and humidity warning range for each sensor. Graphs by hour, day, week, month or year. Haven't tried exporting the data yet, but with a sensor it seems easy. TIPS: You may need to add the 2.4GHz network to your router settings if someone who installed your router didn't set it up or make it discoverable. Download the Govee Home App before switching to 2.4GHz. Please make sure your phone/tablet is connected to the 2.4GHz network before starting the setup in the app. Follow the included instructions to add the gateway part (plug-in) first and then add the sensors. To add sensors: Remove the battery tab from one sensor at a time to avoid confusing which sensor you are adding. Add the supplied number sticker or descriptive label to the sensor, add this sensor to the app and name it Enter the number/label. After adding, remove the battery tab on the next sensor. Switch your phone/tablet network back to a higher band after setup. You don't need to stay connected to the 2.4GHz network to view the status of the sensors in the app, this is only required during setup.
