Govee WiFi Hygrometer Thermometer Sensor 3 Pack, Indoor Wireless Smart Temperature Humidity Meter with Remote App Notification Alert, 2 Years Data Storage, Export, for Home, Greenhouse

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.

Anyone that lives in a multi-story townhouse knows the struggle of the upstairs being super hot or super cold. I wanted to know for sure how the temperatures were in the individual rooms, and the setup was incredibly easy. The app is simple and clean, no million ads. The history is clear and easy to understand, and very accurate when read with a room thermometer. Now I know at all times how hot or cold it is upstairs, and can adjust the temp on the fly. I highly recommend it.

muy bueno, hace lo que necesito

wow, i have a lot of different weather and temp related products and i have to say this one was an easy to setup (not super easy but definitely doable with no experience) but the impressive thing is that it works beautifully and the app is excellent. hopefully the leak alarm notifications work at a distance but i did test them at close range and they worked fine. also, the AI and some info on the product page eluded to it not working with alexa but i tried it and it works well including with echo's and other alexa/amazon products.

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.
