Easy Setup, Lots of Data
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.

Setup was easy, batteries last a long time (unless put into a fridge/freezer), and accurate!
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.

All features are easy to use and easy to read – Excellent support. Recommend
Product works well. All features are easy to use and easy to read. My wife and I use these sensors to monitor temperature and humidity at several locations in our new house. Having recently returned from the south, we are nervous about the upcoming winter in the north. So these units give us peace of mind, knowing that the insulation is adequately protecting our pipes and that the crawlspace is not overly humid.We developed an issue with the first gateway. I opened a job with support. The technician guided me through troubleshooting. Once the problem was identified and verified, he mailed us a replacement unit, and we were back on the air in under 2 days! Impressive.The charting feature is very helpful in spotting trends or aberrationsWe recommend these as an easy-to-use, durable, and reliable method of watching trends and tracking trends.

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.
