Govee WiFi Hygrometer Thermometer 6 Pack H5100, Indoor Wireless Temperature Humidity Sensor Monitor with Remote App Notification Alert, 2 Years Data Storage Export, for Home, Greenhouse

Easy setup, can trend data over time. Just got ever thing setup for wi - fi. Sensors are small about a tenth the size of other brand sensors. Tested remote access outside of home a mile away. Everything works! Nice feature is that you can calibrate each sensor for maximum accuracy to a known source. Cannot do this with common temp/humidity sensors. So you can get all the sensors reading the same. Using this as a remote system when I am away from home. Live at 7,000 ft and it can get cold in a hurry. I have a couple of weather systems and this was easiest to setup for remote monitoring. Data trending is great over a day, week, and month. Gave it 5 stars for easy setup, will see about reliability. Only gripe is you need a magnifying glass to read the manual. UPDATE 1 - Well it has been a week now. Spent a few days in Phoenix away from Flagstaff. Readings are reliable. Still 5 stars. UPDATE 2 - Well I added a second set of sensors and gateway. Now controlling 6 temp/humidity sensors. Called customer service which is a miracle as there a phone number; to see if a second gateway can be added. No problem it can.

These use a single AAA battery, and depending on the location of the hub and the AAA battery used, they last a long time! The setup was easy using the app, and I do have it connected to Govee's cloud so I can access the Hygrometer Thermometer information when out of the house. The hub found the devices without issue, and I was able to add them. I like the Bluetooth feature, as these can be used without a hub, though using a hub is better for the longevity of batteries and WiFi access. I wish the hub included with this pack could have more than 10 devices connected to it, as I'd like to place more Hygrometer Themometers than just 10 of them. Another downside to the hub is that it will ONLY work with HS100s. I have one HS100 outside, then others inside the house in the Kitchen, living room, dining room, Bedroom, and Server Room (aka Spare Bedroom). I have alerts set for temperature and humidity for the server room, as my servers and network gear care a bit more about both! And I occasionally get alerts for both. As for accuracy, the Dining Room HS100 temperature matches very closely to the Thermostat that is in the same room, even though the Thermostat only does full F degrees and not partial. As for battery life, I am using Panasonic Eneloop and EBL AAA batteries. I have noticed that the EBL AAAs drain faster than Eneloop AAAs, so they need to be replaced more often and recharged. I placed one of the HS100s in my fridge, and the battery did not last long, maybe a month if I was lucky. So get the Govee Hygrometer Thermometer that requires three batteries if you want these in a fridge or Freezer. These were my first Govee devices, but I have now bought some light bulbs. I have found that Govee devices I purchased are very good quality, and I will buy more Govee devices, including more HS100s.

This was the perfect solution for monitoring temperature and humidity in my terrarium. I highly recommend getting a mounting bracket. Genepi on Etsy custom designed a hexagon bracket for me so the sensor blends seamlessly with the natural elements in my terrarium. Check out the shop "GenepiGarage" on Etsy. The design they created for me is available for purchase off the shelf. Price was reasonable and shipping was fast. You can even customize the color. I also use these sensors to monitor the humidity near my indoor plants, and the hex design looks great there too. I'm not affiliated with the shop, just super impressed with the work. I really enjoy the functionality of these sensors. You can set up alarms for when conditions go outside of a set threshold, which is super useful. With the gateway you can even check remotely. This was such a game changer for my jumping spider terrarium, and I'll definitely be using these hygrometer/thermometers on future builds.

I bought four of these in order to better monitor the interior temperatures of my multi story home. The interface with my iPhone was pretty easy and with the exception of having to change batteries every so many months the system works flawlessly. It provides room temp at any time plus various reports on humidity, temp fluctuation history etc. It's not going to predict the weather for you but its a decent product and I'm finding them very helpful. FYI I use these since I installed, in addition to my boiler, mini splits for air conditioning and heat. They allow me to keep an eye on all aspects of my homes temperature.

Bought the Govee 5100's with the gateway (x2) in addition to extra 5100's to monitor snake enclosures. Obviously a bit of an esoteric use but regardless, well within the indications of these sensors and functionality. Set-up is incredibly easy. The Govee app feels like you are about to play a video game rather than set up a system of sensors and other connected devices. Not quite the streamlined professional appearance but it's fine for what it is. The sensors connect to the app seamlessly (initially) and then connect to the gateway and wifi easily. No complaints at all. Unfortunately, I don't believe anyone buys these devices so that they can connect them to an app and then walk away. These are monitoring devices for a specific use. While these devices are not lab certified equipment (I trained in biochemistry and molecular biology), they are advertised to measure within reasonable accuracy. And here is ONE aspect where this product utterly fails. When I set these up, I noticed that I was getting readings that varied by 1-2 degrees F between sensors that were nearly side by side. I then bought a thermometer with an NIST certificate to measure against these devices. This more or less confirmed that they are accurate within typically +/- 1 degree F. For what I need it for, I decided that this was acceptable so I continued using the sensors. BUT......after about 2-3 months of using these sensors and gateways I started to notice that monitoring the snake enclosures remotely was becoming less reliable despite no changes in my home wifi network. Since I travel a lot for work, remote monitoring is considered essential for me and a large reason I bought this set-up. More and more frequently, when I tried to update the sensors remotely the wifi would not update through the gateway. THEN, I started to notice some of the sensors would not update despite the wifi gateway updating the other sensors (I'm using around 12-14 sensors). The battery would indicate full yet the sensors were not updating. Changing the battery would only fix the problem about half of the time. Deleting the device from the app and reinstalling it would fix it about half of the time. The problem though is that some of these sensors would just completely stop being found by bluetooth when you try to reinstall them. Govee support has been responsive and has agreed to replace the sensors (I have still to actually receive replacements) but honestly I have no trust or confidence in these sensors and am going to probably eat the money and find something else that is reliable. I don't need laboratory accuracy but I do need to trust that when I am away the sensors I am using are actually working, are going to work and are going to last longer than a couple months. Overall, definitely would NOT recommend this unless Govee makes some real changes.
