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.

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.

I originally purchased these to keep track of temperatures in the RV, but found that I could put one out in the heated room, in the house screen room, for my wife's plants (during the winter), and under the water-well cover to make sure that the heater kept the water-well head warm but not hot. And I can monitor these all from my phone. These things are great, very useful and have helped put my mind at ease concerning maintaining proper temperatures where needed. And the RV never got to hot or cold, thereby preventing humidity problems that might result in mildew or mold later.

Govee products tend to be very good quality for the price point. The app is very easy to use. These small thermometers are great to put in fridges, freezers, rooms, attics, outside (protected), and more. Pros - Setup was a very fast through the app - Thermometers connect to phone via both Bluetooth and WiFi so you can always get a reading. - Plug in gateway works with several other devices (all thermometers) we already had. Surprise! - Easy to swap AAA batteries - Comes with numbering stickers - Temp history is very important. Many devices now have a thermometer built in but do not show history. You need to know if temps got to unsafe levels at any point regardless of current readings. Especially with food. Uses - Fridge and Freezer - Set alerts if temp gets too high. Know if door is left open, power goes out or device stops working. Move to different areas to find cold and warm spots. - Power Out - Monitor temps throughout power outage to know if your food and things are safe. - Swamp Cooler - We keep near swamp cooler to get exact temp and humidity to ensure it’s working as expected. - Automation - Use these readings to trigger automations with other Govee devices. - Cigar and Wine Storage - Keep the humidity and temps right where they need to be.
