Govee New WiFi Digital Hygrometer Thermometer 3 Pack H5151, Indoor Outdoor Smart Gateway Room Temperature Humidity Sensor, Wireless Temp Gauge with App Alert, for Home, Greenhouse(not support 5G WiFi)

Anyone that lives in a multi-story townhouse knows the struggle of the upstairs being super hot or super cold. I wanted to know for sure how the temperatures were in the individual rooms, and the setup was incredibly easy. The app is simple and clean, no million ads. The history is clear and easy to understand, and very accurate when read with a room thermometer. Now I know at all times how hot or cold it is upstairs, and can adjust the temp on the fly. I highly recommend it.

I originally purchased these to keep track of temperatures in the RV, but found that I could put one out in the heated room, in the house screen room, for my wife's plants (during the winter), and under the water-well cover to make sure that the heater kept the water-well head warm but not hot. And I can monitor these all from my phone. These things are great, very useful and have helped put my mind at ease concerning maintaining proper temperatures where needed. And the RV never got to hot or cold, thereby preventing humidity problems that might result in mildew or mold later.

Works great! Not thrilled that it's something probably made in china. But it works for what I need, and that is to remotely monitor temps. Easy setup. Easy to use app. Has 3 sensors so you can monitor different areas of a building or outside. One battery in each. Seems to last fairly long, even on the one outside when its freezing cold all winter. Probably change the battery once or twice a year. As long as you have wifi for it to connect to, you'll be able to remotely monitor temp and humidity levels from anywhere using the app. And its nice to see historical data too, and the weather trends over various periods of time. It'll show the min and the max temps, as well as the overall average of the temp swings too.

I use these sensors when incubating quail eggs. They are much more accurate than the Thermometer and Hygrometer on any of the incubators I have, even the $500 incubator. The individual sensors connect with Bluetooth to my phone just like several other Govee sensors I own. With the WiFi hub in this package, I can monitor the new sensors even when I'm not home. It'd be great if the hub could support the older units I have, but overall this is a great product and a must if you're incubating eggs. Edit to add: I recently purchased another 3 sensors and added them to the gateway. While doing that, I upgraded the firmware on the gateway as well. After the upgrade, I discovered that the gateway was able to communicate with the older sensors I had. All was good with them until 9/5/24 when the gateway became unreachable via WiFi. I've tried every troubleshooting procedure I could think of and done everything that Govee Customer support has suggested, but the gateway no longer talks Bluetooth and won't connect to WiFi. Of course, it's out of warranty and they don't sell the gateway separately. The individual sensors still work so it's not a complete loss, but I'm deducting two stars from my original review and can no longer recommend the gateway. Update 9/12/24: After a bit of back and forth with Govee Customer support, they decided to send a new gateway to me at no cost. It arrived today, along with 3 more sensors, and works flawlessly. I restored the previous star rating to this review and can now recommend the product again.

I picked up a set of Govee humidity and temp sensors to help me keep my house safer in Jan of 24. I love them, they're great little sensors, they were easy to set up and use. Unfortunately the gateway just up and stopped working a little over a week ago. I contacted Govee support hoping to be able to buy JUST a replacement gateway. Well, they don't sell just the gateway, but... I was a little surprised when they offered to just send me a replacement. Ok, Great. Problem solved. Now imagine how surprised, and very pleasantly so I might add, when they sent me a whole new SET, the gateway and 3 sensors. I will Definitely be looking at Govee to fulfill more of my smart home sensing and lighting needs in the future.
