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

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.

It was described exactly as it was. Love the fact that I can put it anywhere and it is portable and easy to take anywhere.

best devices to give me peace of mind on monitoring my extensive doll collection,I highly recommend them.

I had something like this I bought many many years ago. of course sitting side by side the two of them didn't exactly match one another but I think they are all right. I think this unit has a better humidity measurement than my previous units they generally always agreed with one another but these two units will more closely match my Nest so I think I trust them more. two units is perfect for my 2 story house one is on the same floor as my dehumidifier and the other one I keep in the bedroom.

i like it all the way around...look forward to its use in my house

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.

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.

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.
