Govee WiFi Thermometer Hygrometer H5179, Smart Humidity Temperature Sensor with App Notification Alert, 2 Years Data Storage Export, Remote Monitor for Room Greenhouse （Only Support 2.4G Wi-Fi）

I didn't realize how hard it was to find a wireless thermometer for my deep freezer (wifi or ZigBee). This sensor is wifi based and has had no connection issue in my freezer in the garage. It was rated to -4degrees which is perfect for my freezer. I did have to add about a 2 degree shift to the calibration, just turn it on, leave it in a place that you know the actual temp for about an hour or two and use the app to change the calibration. The app is very easy to use. I highly recommend this one over the others.For home assistant users: I found a forum that explained how to use rest commands to bring the wifi data into home assistant. This worked great and was very easy to get integrated!

Works perfectly, very easy to set up. The temperature readings seem to be very accurate. Battery life has been fantastic in the month I've been using it, still shows full. I love that the thermometer includes humidity readings as well. Overall a great product for peace of mind when I'm not at home

This has been a perfect solution to my issue. I have a server closet that has a mini-split ac unit that will occasionally have a issue and if I don't check the room often I don't know and it can get too hot with those servers running. This was a perfect solution where I can check the temp but also set an alarm so as soon as it exceeds a temp I get notified. The setup was easy however my device did not work. I contacted their support team and they sent me a replacement right away which worked perfectly so support was fantastic.

I bought two sensors to monitor the inside temperature at our off grid cabin in the winter when we are not usually up there. They were easy to set up and I tested them at our house for a week to make sure they worked before installing them at the cabin. It’s about a 1.5 hour drive to get there so I was hoping not to have to make several trips to get it right. It was pretty easy to get them connected to the Wi-Fi at the cabin and they worked well for about a month. Then one day I noticed that one of the sensors had lost its Wi-Fi connection. There is no way to reset it remotely so I was planning to drive up there on the upcoming weekend and check it out. But magically, the next day both sensors were again working. That held for a week then it lost the connection again for two days. For the last two months, either sensor will randomly lose then regain its connection in a day or two. Fortunately, so far at least one of them has always been connected. I did send a report to Govee but their reply was not real helpful. Mainly they advised that I go there and reset them. But since they seem to reconnect on their own I don’t see the need for that.Right now I can work with this random connection issue, since the majority of the time they are working as expected. If it gets worse I’ll contact Govee again.But overall I do like these sensors and the Govee app. For the price it’s doing a good job providing the information we need.

Easy wi-fi setup, excellent app, and build quality appears good. I bought it to monitor the humidity in a crawlspace. Govee advertises hygrometer accuracy of +/- 3% RH, which I checked to my satisfaction using the salt test. It's too soon to tell how well the Govee lasts in a crawlspace, but I'm guardedly optimistic based on what I've seen thus far. I'd buy it again.

F---I purchased a package of 2 and one works great. I love it. But the second one started randomly disconnecting from the wifi and no temperature data was sent to the app. This happened just about 45 days after my purchase. So I took the batteries out, removed the device from the Govee app, and reinstalled everything again. Just like the troubleshooting video explained. The bad unit started working again.Then, less than 3 months after my purchase, the unit stopped working again, no wifi data again, and no warning that the app lost connection. When this happens, there is no warning, so I have no idea that my freezer is not being monitored.The unit is truly defective because I have tried their "fix" that their support process instructs you to do. The unit is dead in less than 3 months and there is no option to return it.The short story is that I have two devices to monitor my 2 freezers, but only one works, so your chances are 50/50 that you will get what you pay for.Now I need to look for a different product.
