Govee WiFi Temperature Humidity Monitor, Wireless Digital Indoor Hygrometer Thermometer with App Alerts, Temperature Sensor Humidity Gauge for Home Pet Garage Cropper Greenhouse(Don't Support 5G WiFi)

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 to monitor temperature in travel trailer stored and used in Wi-Fi areas. Easy to change Wi-Fi, but phone must be within bluetooth reach of device when changing. Just connect your phone to Wi-Fi and open the app and change the Wi-Fi. Do not have to reset the device. Has low battery alert, but battery has been good so far. Remote monitoring of temp and humidity is great. App even has charts and alerts. No subscriptions needed. Thinking of purchasing additional devices for other locations.

It was very easy to set up and the app is pretty easy to use. I did need to calibrate it because it was initially reading about 20 degrees cooler; the calibration is pretty easy to do through the app, but it's limited. I could never get it closer than about 10 degrees cooler than the real temp, but it was reading consistently precise allowing me to just add 10 to the reading for the real temperature. I was able to get the humidity to be almost exact. I would recommend this product if you have reptiles. I bought it for my frilled dragon when she became very ill and I wanted to check her temperature and humidity throughout the day; I could be at work and look at the graph the app generates to see how good things were throughout the day and have the real-time reading. But, like I said, have a secondary temperature reader for your reptiles since you may need to calibrate this product. I always recommend a temperature gun if you keep herps. Unfortunately, after about 2 months, the product stopped working. I did purchase a 3-year warranty, but they still have a good guarantee on the product. So, they have a rapid-replacement feature on the app. I was able submit my problem and send pictures; then, they got back to me in in less than 24 hours telling me that they would immediately send me a replacement. Their email also outlined when it should ship and when it should arrive, which is about 4 days after shipment. So, overall. I would say that I have so far had a good experience with this product and the company.

Item was non functional from opening the box

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.
