Geevon Bluetooth Thermometer Hygrometer, Indoor Temperature Humidity Sensor with HD Display, App Notification Alert, Historical Data Storage and Export(3 Pack )

Overall, I am pretty satisfied with this temperature gauge. While I can't verify if the hygrometer's reading is correct, the thermometer seems very accurate when compared to my house's AC reading. As mentioned in the manual, it took exactly 30mins after powering it on for the temperature to update and become accurate. Connects to the WiFi easily, but you do have to use the SmartLife app and give it your WiFi password to update the clock. It was easy to swap from Celcius to Fahrenheit by clicking the button on the back of the device. I appreciate that the display is very easy to read, even when the backlight is not turned on. It's also nice that the device came with batteries installed.

I like that it has a little face on there to tell you the if the humidity range is good or not( it smiles or frowns) so you don't have to look up the ideal range constantly. The bluetooth range is about 33 feet for me(which is pretty normal I think)The accuracy is almost the exact same as the thermostat on my wall. I like that it came with a tool to open the back for the battery(battery is included )but it was kind of weird that the tool they give you is made from PCB(basically a computer motherboard). All in all these were pretty good and easy to set up.

Setting it up was pretty easy and I haven't had any issues with it yet. I like the button on top that turns on the backlight to the screen, you barley have to put any pressure on it (I think its called capacitive )It has 2.4 wifi so the range is pretty good and the app is pretty easy to understand and use. All in all I think this is a pretty decent device.

A nice little unit and a nice display. Would have been nice if it had an option to remotely power it to keep the display lit, instead you have to touch it to bring on the backlight. That’s the only reason I rated the display as 4/5. It’s nice that it included batteries and it was pretty easy to set up. The temperature reading I believe is right on, I suspect that the humidity might be off by just 2-3% based on my standard. The manual refers to being able to put in an offset to correct any error, but the description on how to do it in the manual is insufficient. Being able to add an offset is great as far as keeping it accurate for years to come. I’ve reached out to their tech support for an explanation on how to do it and I’m waiting for a response. Over all, I like the unit. It’s WIFI via SmartLife which I already had the network. The app is included if you need it and the data, including trends, are displayed on your phone. SmartLife also allows you to run scenes (programs) to other WiFi modules, but don’t let that scare you if you don’t have any. Take note that the unit won’t be accurate for roughly 30 minutes when you first power it up per the manual.

Measuring instruments are special tools used to find out the quantity of something, such as its time, humidity , or temperature. They are very important because they help us be accurate and fair in our daily activities. Geevon meets or exceeds all above requirements with the clock, Hygrometer, Thermometer with Large LCD Display.

This worked exactly as described with one minor glitch it's easy to read you only have to basically wave your hand over the top surface for the light to come on the numbers are large and very distinct and they're pretty accurate I'd say within 1° C and that's the minor glitch it won't display Fahrenheit on the display although it will read Fahrenheit in the app. I have experience with this type unit before andInvariably they all reset within 24 hours.This one did notI attempted to reinstall hit reinitialize itIt didn't make any difference. If you're comfortable working with Celsius then I would say grab thone; they're they're tremendous bargain.

The Indoor WiFi Hygrometer Thermometer works fine. To see the temperature, you need to install a special app on your phone, which I think is a downside. It has a backlight and a power-saving mode, which makes sense because it runs on batteries. The batteries were already included. It shows the time, but it’s not very prominent, and there’s no date. Overall, it’s okay, but I think you could find a similar device with more features.

These don't connect to your home network. Only to your phone's bluetooth, and worse than any other bluetooth device I've ever used. You have to be in the room with the device to get it to connect, then it takes longer to open the app and get it connected than it would to just go look at it.

Not impressed with this at all. I can’t get it to read the temperature correctly. And Ci can’t get it to connect to the WiFi. And it’s unsecure network. It’s been reading 75.5 the whole time it’s been on. And I had it on the AC to see if it brings the temperature measurement down. And it did not.

This is close to being a scam. If you wish to receive notifications from device as described, they what you to sign up for a service plan starting for $49 per month to $120.
