GoveeWiFi Hygrometer Thermometer Sensor 3 Pack, Indoor Wireless Smart Temperature Humidity Monitor with Remote App Notification Alert, 2 Years Data Storage Export, for Home, Greenhouse

I really like these thermometer/hygrometers. They are quite precise, displaying temperature and humidity to the tenth. The historical data is fantastic as well, as it's easy to look at trends over hours, days, weeks, months, or the entire year. Although I've only had them for a couple months, so no long-term experience yet.Initially, I tried one in the RV freezer, one in the RF refrigerator, and one in the RV living room. Yes, there is an "RV" trend there. We are camping out in the RV while the house is remodeled. Anyway, we wanted to monitor the temps in the freezer and fridge zone to ensure they were cooling to the right levels. And they were. And yes, the signal worked right through the refrigerator doors. The base unit was placed about 15 feet away under the dinette (cause that's where the outlet is). :)As the season progressed and it got much colder, we were more concerned with the temperatures around the freshwater tank and the underbelly area. And we were right to be concerned. The freshwater tank or the feed from the tank to the pump froze when we had the cold snap in early December (Oregon). How do I know it was the tank or tank line to the pump? Well, our RV has a feed hose with a cutoff valve right before the pump. So, I filled a bucket of water, put the feeder hose in the bucket, and ran the pump. Pressured right up and the sinks worked. So, frozen tank or feed line.Anyway, we skirted the RV with cellular foam board, put a small space heater underneath with a thermal switch, and placed the thermostats. One thermostat was hung under the frame in the now enclosed underside of the RV. One in the pump area with all the crazy water lines. And one just outside the RV hanging from an external panel. The lanyards came in handy for that.We were happy to see the underbelly temps come slowly back up above freezing. At this moment (22 Dec 22), it's 36.9 degrees in the underbelly, and 10.4 degrees just on the outside of the RV. And yes, the water unfroze, and everything works again. Yay! We carefully checked for any leaks and were happy to not find any.So, we really like the sensors. They are connected over our home network, so I can check them anywhere, anytime. The Govee app is nice and easy to use, and it's easy to add the devices. I did get one bum battery that died in the first week, but that inconsequential. The others are running strong. And they work fine with our Eneloop rechargeables.Small, precise, and wireless. Good stuff.

I first bought this kit of 3 sensors with WIFI hub about a year and a half ago, when I had our heat pump replaced. I liked it right away, and I ordered an additional 6 sensors within 2 weeks of the initial purchase.We have a large house, with one thermostat located in the Livivng Room. I placed 8 of the sensors in various rooms in the house, and 1 outside on the deck. It turns out the temp in the Living Room was not representative of the conditions in the other rooms in the house.Before I placed these sensors around the house, I set them all next to each and let them sit for an hour.They all reported temp and humidity readings very close to each other, with temps being usually 1 degree different. The difference between the highest and lowest was only about 1.5 degs different. Each unit can be adjusted up or down to make the temps match exactly.What I like about these:They are accurate.They are small and inconspicuous.They use 1 AAA battery which lasts a few months.They notify you, via the app when the batteries get low.They continuously log the temp and humidity readings.You can see a graph of the readings in the app, over a time span that you choose, over hours, over 1 day, over several days, over weeks and months.I did not want to go through the trouble of moving my heat pump thermostat to another location in the house. I use the Govee sensors to set the thermostat so that I get the temps that I want in the locations that we are in, i.e. the Family Room, Master Bedroom.I think these Govee sensors are very practical, and well worth the money.I just bought another set of sensors with WIFI Hub for our weekend home, with which I'll be able to keep tabs on the temps and humidity conditions when we aren't there. ( We're most concerned about the humidity getting too high while we are not there).

These thermometers were very easy and quick to set up and connect to the app on my phone. They are working great and track the temp and humidity data directly in the app through wifi. 10/10 would recommend.

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 have their water detector that has worked great for a couple of years and needed to know about temperature and dewpoint over time so I took a chance, bought this, and have been impressed with amount of information that is collected and presented. Easy to set up.
