Tidy little unit. Properly rated for use in humid environments like a humidor. All 3 I purchased are very close on the temperature readings. The %RH only resolves to 1% and they seem to be +/-1% which could actually be closer due to the limit of resolution. Works great for my needs. I can also retrieve the readings a floor away even though they are inside a humidor.

This is a great little device at a bargain price. It uses 2 AAA batteries which come pre-installed and are estimated to last 2 years. The app is easy to use and shows current temperature and humidity (as well as some other measurements) plus is able to store thousands of readings which are displayed graphically. I was also able to successfully upgrade the device's firmware using the app.Connectivity is via Bluetooth and in my case I am using the device outdoors and needed to have it placed quite close to the house in order to establish a connection but then I live in an old house with very solid stone walls.I can't comment on the humidity readings but the temperature readings certainly appear to be accurate.All in all, I'm very pleased with the device and recommend it.

Initially, I was hesitant to get these, as I really needed a bunch that would really work in different environments. After a year of use and adding about a dozen to my Hub 2s and working with Matter on Apple Home, I have to come back and just gush about how incredible these are!First: when paired with the SwitchBot App and cloud services, these things are incredibly. They store loads of data that can be viewed in the app on navigable graphs. Even better: you can just mass export the data to spreadsheets to view elsewhere.Second: the Bluetooth range is insanely good. I have some in my refrigerator and I can connect to them in my bedroom. Yes, it’s still Bluetooth so, the connection is hampered by the fridge door & bedroom door, but that it is even possible is a testament to how good these things are. I wouldn’t rely on the Bluetooth for my scenario, however, and I don’t have to: I can use the cloud services to more reliably connect.Third: Matter is excellent for these when paired with Hub 2 and my Apple Home Hub. The SwitchBot App treats both the temperature AND humidity readings of these as 1 device for Matter. Still, Apple has been able to treat the temperature and humidity sensors as distinct “devices” connected to the Hub 2…which is exactly the best case scenario (I save one of the 8 Matter Device slots that you are limited to per Hub 2, but still get 2 devices in Apple Home).Fourth: These really do work in harsher conditions. I have them in a bathroom that has regularly surpassed 70-percent relative humidity, in my freezer, and in my refrigerator.i haven’t had any issue. You can hang them via the lanyard, drop them on a shelf, stick them to a wall with the included 3M tape…I’ve eveb used command strips with them!They really are a value: especially when you get multiples. The sensors are just as good as the Meter Plus (which I also use), but without the screen, a longer Bluetooth range, smaller form factor, and higher whether resistance ratings.both are excellent for seeing trends and checking in on the climate at any point in time.The more you have, the better: I’ve been able to track micro changes in my apartment to fine-tune a dehumidifier. I went from a swampy house to one that is actually comfortable in part because of these.Highly recommend these! Hope this helps!

3 devices with iPhone appI found initial setup to be very easy with QR code to download the app and simple instructions both written then continued on the app.Bluetooth found each of the 3 devices quicklyInitial reading is questionable1 placed outside2 placed side by side in front roomAfter updating the firmware on all devices, As screenshot indicates, the 2 hanging side by side have a difference 1.8 degrees (71.4 and 69.6)After refreshing the app over 10 minutes, the temperature reading stabilized to less the 1 degree difference. For the price, I consider that acceptable.Humidity difference of 1% seems acceptable as well. As for accuracy, I have nothing to compare to except the weather app on my phone which probably says nothing.Overall quality seems good. Functions as expected at this point and app appears to meet my needs if not exceed.UPDATE 2 days later:Seems to be stable and accurate enough for me but I found where to calibrate so if it’s a problem, the app provides a solution.Overall very pleased. I even learned about the VPD reading and that lowering humidity in the camper may be great for the camper but not so great for me (sinus headache a clue) - as with everything- BALANCE. Ideally VPD should be lower but because I’m not comfortable at cooler temps, I have to find a happy medium.If I don’t update this review further, it means all is well.At this point I will and do recommend.

De thermometers zijn mooi afgewerkt en niet groot. Het batterijdeksel is afgewerkt met een rubber dichting. Werkt op 1 AAA batterij (meegeleverd).De app is handig en een mooi overzicht van meerdere weken. Verbinding is via bluetooth rechtstreeks in de app of via een Relais (apart aan te kopen) via wifi.Ik kocht een 3 pack zonder display en ben er heel tevreden over.

***1 month update: basement freezer sensor is no longer connected. I didn't get a notice that it disconnected, I just happened to notice that it was no longer reading. I even set it up to notify me for low battery sensors. I got no notifications at all but after replacing the batteries, it seems to be functioning correctly again. ***Item was packaged well and included simple instructions for setup. I noticed right off that the cords that the minihub uses are the old style USB connections and the package did not include a power adapter, which to me is absurd. If I paid for a working item but the item I received lacks the ability to even plug into a power grid, obviously I did not get a working item for the price I paid. I knocked a star for these reasons. Other than that, the item works well. It was just a bad first impression and I was lucky to have an extra adapter handy or I would have had to order and wait on that item as well before being able to use the remote thermometer I desperately needed to more accurately monitor our large tortoises' house in particularly bad weather. The items create a temp graph as they go, allowing me to see trends in the heating elements during the day and night. These are way more accurate than the brand I was using before. I threw the other two sensors into my deep freezers and now will hopefully get alarms before I get spoiled food in the event of a freezer failure. I like that I was able to integrate it easily into Google Home and can now ask the hub or my phone, "What temp is the basement freezer" or "What temp is the garage freezer" and it will instantly tell me. This was our first automated purchase and for the most part, we are very pleased with it.
