GoveeWiFi Thermometer Hygrometer H5051, Bluetooth Indoor Temperature Humidity Monitor with App Notification Alert, Smart Humidity Sensor for Greenhouse Wine Cellar, 2 Years Free Data Storage Export

This product has been a fantastic addition to my home! I have a "She Shed" that houses a very expensive industrial laser engraver, as well as other expensive pieces of equipment. Constant temperature monitoring is vital, as dropping below freezing will cause the laser tube to crack, which is an $1800 mistake. After having that situation happen last year, while using a bluetooth temperature monitor from a different company, I started looking for something different. I love Govee products, so naturally, they were my first choice. The WiFi and Bluetooth connectivity make it easy to check readings remotely through the app, and the alerts are super helpful for keeping conditions stable.It works exactly as I need it to, and it is incredibly accurate. Highly recommend!!

We use this to monitor the temp inside our RV while we are gone and leave our dogo behind. Works well, set up is a breeze push notifications warn us if it is getting too warm or cold inside the coach so we know the little guy is comfy and safe. We travel full time so this gets a lot of use. High recommend

We bought 5 ($75 each) of these in December, 2018 to monitor our summer house during the winter, and make sure we did not loose heat from our old boiler. After some work, I got all 5 to work. Left town, and headed for warmer weather. At first they all worked, and I was glad to see the data. Over the course of 3 months, they all disconnected one by one. By the time the last one failed, it was March, 2019 and we were past the high risk winter temperatures. When we returned to the summer house, I saw that the displays were still working but no connection. I simply put them all in a drawer. In late October, 2019 it was time to get the house ready for winter again, and I decided to check them out before finding another brand. All the displays were dead. I tested each of the original batteries, and found readings from 0.01v all the way to 1.00v. Like a bunch of random numbers. Good batteries do not run down like that. These were clearly really cheap batteries. I replaced all 15 batteries with new Kirkland AAA batteries that I already owned. Those all started at about 1.59v. All 5 units instantly jumped back to life, automatically reconnected, and started reporting data again. They were all as good as new, and and fully wifi connected. No need to re-program.Moral of the story is to throw away the included batteries as step one. Put in 3 high quality batteries. I suspect the batteries are the source of many many problems people are reporting. Not sure how much time to expect, but 5 or 6 months is all that I really need to have. I will buy one or two more, depending on whether or not wifi can reach the garage. That allows me the ability to see temps in every cold corner of this large house with radiant water heat in wooden floors. With more than a mile of copper / water pipes in wooden floors, I can not allow the house to ever ever freeze.These work great, with great reports. They just need a good power source.

Purchased three of these to monitor the temperature at our church. They were deployed a month and a half ago, have a strong connection to wifi and are set to refresh every 30 minutes. Battery life is excellent - they are only down one bar. They have been reliable and are reasonably in line with our hvac sensors. I purchased these so we could better see the trend lines in temperature change and get alerts for temps outside center parameters. They have worked well. I have two minor complaints (thus taking away one star). I would like to be able to adjust the settings remotely. That does not appear possible unless you are in Bluetooth range. The second issue is when first set up, they worked on wifi for a short time then needed to be reconnected. (They have worked fine since then). It is an odd glitch. However, these are excellent devices and I’d recommend them to anyone. We will probably add a few more and look at other Govee products. These are dead simple to setup and have worked well.

I have ordered multiple Govee temperature-humidity sensors. I have three each of models H5075 (Bluetooth only with data display), H5051 (WiFi and Bluetooth with data display), and H5053 (older WiFi version with hub, no data display, but weather resistant). I also have one model H5179 (WiFi and Bluetooth with no data display).First, I would like to say that I was surprised and pleased by the accuracy (or, more precisely, the repeatability) of the data with these units. Before deploying them to their final locations, I lined them up next to each other to see how well they agreed on the temperature and humidity. They did so to within the specified accuracy, so I trust the specifications. (By contrast, when I have looked at racks of thermometers in stores, all in the same place, I have been struck by the wide range of readings, including some wild outliers.)I wanted to use one sensor outside. Models H5051 and H5075 clearly would not stand up to rain; I hoped that perhaps model H5179, which looked pretty well sealed, would. It did not; it died after the first heavy rain and never recovered. Govee does not claim that it can be exposed to rain, so I do not blame them. I report the fact here in order to save others from wasting their money on an unsuccessful experiment.Eventually I found on Amazon the older (obsolete?) model H5053 set. It is advertised as weather-resistant. I asked Govee about it, and they advised not exposing it directly to rain. I mounted it under a porch, near the outside but not directly exposed to rain. It has been running nicely for more than a month. In the end, I also ordered an Ambient weather station, whose temperature-humidity sensor does work with direct exposure to the elements.If you do not need to access the data when far from the sensors, the model H5075 units are to be preferred. They are much cheaper than the H5051 units with WiFi support. The Bluetooth-only units work very nicely in my home and on my phone when I am at home.I do wish that one had the option to display dewpoint temperature instead of or in addition to relative humidity. The firmware in the units probably cannot be updated, but the phone app could be improved to offer this option.I cannot comment on battery life, as I have not had the units long enough. Also, I do not use Alexa.One final comment. As others have reported, getting the units set up and configured is sometimes not as straightforward as one would like. I recommend patience and persistence. Sometimes initial attempts failed, but in the end all the units got connected.
