SwitchBotIP65 Indoor Outdoor Hygrometer Thermometer Wireless 3Packs, 394ft Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, 2-Year Battery Life, Free Data Storage

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!

I love these little sensors. I have a couple of them inside my house in closets/storage areas where I want to monitor temperature and humidity.I also have one that I keep outside to monitor outdoor temps, especially important to monitor my plants for freezing and our brutal summers here.I monitor these with the switchbot app, Google home app, and in home assistant via bluetooth. I get nice graphs and can take actions based on temps, etc.Also, the price is right!

***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.

Super happy with these. I use them for monitoring a server closet, rooms in the house and even outside. They work really well with the SwitchBot hub. They have a very good range considering how lower power they are and they can go through walls. The company puts out firmware updates and seems to really support the product. On top of all of that, it works really well with HomeKit through the hub. (You need a hub for HomeKit support!)
