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.

The house is in the country and on a different electricity provider than our house is. Also, there is a poorly insulated (by me) pump house made of metal in which I put one of these. It's difficult to get the signal to it from the house through the metal and double sided foil lines flexible insulation, but I stuck an empty plastic bottle under the edge of the doorway to this janky structure and moved the sensor closer to the place where the bottle is and the connection has since remained stable. The pump house is maybe about 80 feet away from the router inside the house, so there is a lot of stuff for the signal to get through.I needed to be able to monitor when the temperatures dropped to near or below freezing inside the house and inside the pump house. These sensors have done the truck for me through a relatively long hard freeze here in Texas.So far, I've had to replace the batteries in 2 of the 6 sensors in 2 months and it looks like I'll be needing to change the rest of them soon. They seem to go from showing 2 bars of battery remaining to none as far as I can tell. The one I have in the garage (which was the first to need changing) is already looking like it will need changing again soonish. They're easy to change, but I really would like to get them on rechargeables once I've used up all of the batteries I currently have on hand.They seem relatively accurate compared to others weather stations inside and outside the house and compared to the officially reported temps. I calibrated them all in the same room before placing them in their final positions.Getting them connected to WiFi wasn't all that straightforward, and it took me a bit of time. Once I got one done the others were all easy though. Another reviewer here detailed something they did that made it work and I followed their lead. I can't remember what it was. I did not find the installation guidance of the app all that clear nor the app itself all that intuitive. There's a lot going on in that app that seems confusing and unnecessary to me, but that may be because they have so many devices available to buy and use on a hub - I'm not sure.At any rate, in spite of my hiccups with it, I'd recommend it. Just know you might hit snags with installation and search the reviews here for some tips. Also know you'll be going through batteries and put them in places easy to reach for ease of changing them out.For the price, being able to monitor the temps remotely in 6 different areas of my property and one at a relatively long distance away from the router, this set of sensors and hub is worth it to me. It provides me needed peace of mind regarding the temps and safety of pipes and expensive pump equipment by warning me via phone notification when things are outside of expected parameters.

These work great! Have alerted us to when we accidentally leave the fridge open. Can make it alert us for certain temperatures. Battery life is good and app tells you when you need to change them. Easy to use and set up in the app.

We’ve had these for about 18 months now and still love them. So easy to use and have had no problems since we set them up. We bought them to put in each fridge and freezer after losing an entire freezer of meat after not realizing it had lost power. They don’t run through batteries and always give us the info we need. We get alerts when the temp rises to a preset amount - we can even tell when the kids have been in and out of the fridge constantly! We bought a few extras now to put in miscellaneous rooms, garage and chicken coop to keep an eye on temps and humidity.

The Govee WiFi Hygrometer Thermometer Sensor 3 Pack offers remote monitoring of temperature and humidity for your home or greenhouse. Let's see how it stacks up:Pros:Remote Monitoring: The Govee app allows you to check temperature and humidity readings from anywhere with an internet connection. This is a great feature for monitoring your greenhouse or ensuring your home maintains comfortable conditions.Multiple Sensors: With 3 sensors included, you can track climate data in various locations within your home or greenhouse.Smart Alerts: Set custom alerts for temperature and humidity levels outside your preferred range. This can be helpful for preventing your plants from experiencing extreme conditions or for maintaining a comfortable home environment.Long-Term Data Storage: Govee offers free data storage for 2 years, allowing you to track trends and monitor changes over time.Easy to Use: Users report that the Govee app is user-friendly and set up is relatively straightforward.Cons:Wi-Fi Connectivity Required: These sensors require a Wi-Fi connection to function, which might be a limitation if you don't have Wi-Fi in your desired monitoring location.Limited Range: The sensors don't support 5 GHz Wi-Fi networks, and the range might be limited depending on your home layout or the distance from the Wi-Fi router.Accuracy Concerns: Some users report minor discrepancies in temperature and humidity readings compared to other hygrometers.App Reviews: While generally positive, some app reviews mention occasional connectivity issues.Overall:The Govee WiFi Hygrometer Thermometer Sensor 3 Pack is a convenient option for remotely monitoring temperature and humidity. The multiple sensors, smart alerts, and long-term data storage are valuable features, particularly for those concerned about maintaining stable environmental conditions. However, the dependence on Wi-Fi connectivity and some user reports of minor accuracy variations are factors to consider.If you're looking for a user-friendly and affordable option for remote climate monitoring, and Wi-Fi connectivity isn't a major concern, the Govee WiFi Hygrometer Thermometer Sensor 3 Pack might be a good choice. However, if you need a solution that doesn't rely on Wi-Fi or require high-precision readings, you might want to explore alternative hygrometers.
