SwitchBot WiFi Thermometer, 3 Pack

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!

Reliable, accurate, long battery life. I started with one of these and now own 7. Along the way I bought a min-hub so I can monitor home temperatures remotely, like while travelling. Great price, great performance, recommended.

***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.

Love these for the simplicity of set-up and the peace of mind when I’m traveling! I have them in each freezer, as well as both refrigerator compartments. It’s simple to set up a temperature alert. No more returning home to a weird smell that precedes the “my refrigerator died last week” scenario!

I grow photoperiod plants and can't go into garden at night to check readings of thermometer and hygrometer during dark hours. This little device allows me to accurately adjust the space heater to save some watts and still avoid dewpoint with confidence. The electricity I save will pay for this probe in no time. Not having to reference a dewpoint or VPD chart is a bonus. I like that I can export the data. I'll link that file to a spreadsheet and automate the generation of graphs, min/max data, etc... The app is okay. It works well enough. You can adjust scope of displayed line graphs for daily and larger, but not for hourly. The text is really small and hard to read in spots. It has a ton of advertising and marketing that you can avoid, but i'm not a fan of it having a "shop" feature. It's intrusive and unecessary. thankfully it isn't prevalent in the 'home' screen and you can avoid see it, but it's still there wasting space and resources turning my device into a gd billboard for commercials... that's ridiculous. Outside of the intrusive marketing nonsense, I'm glad I bought this product. Purposefully hamstringing wifi connectivity so that you have to buy their hub is contrived and lame, though. Some business practices are a bit sketchy it seems. Update: They just erased my last update.. They have designed this product to be annoying by design. It cannot even do a simpe file export to my desktop nor write the exported file to the phone's memory. Instead you have to log into 3rd party site in order to get a ling to MY file? Why am i even connecting to any location on the internet when i do not need to? This is ridiculous. They blamed this on the android phone, as if they don't write their app and have no control over how THEIR app works. If i wasn'at technologically inclined, i may have believed their poor excuse. Also, this junk needs the hub for certain functions, which again is totally unecessary. you can see other products work directly from the app on the phone. This is a choice by the manufacturer. A choice to make you more likely to log into some nonsense 3rd party site to collect info and allow access to my file.. it's not 'their' file. There is no reason for them to write an app that functions this way unless by design or simply incompetent. Overall, a lot of shady behaviour here.. unnecessary hoops that probably benefit them or their partners in some way or simply not good at writing a companion app. Flip a coin.

I hang an "Outdoor Meter" from the basement ceiling. Meter comes with a loop for easy hanging. I didn't get a hub, I just use Bluetooth to see what's happening. It might be interesting to hang another outside by the north side of the building, where the sun never shines. But there are enough personal weather stations in my neighborhood on the Internet, so generating my own data would be redundant. If I had to find a complaint, it would be that I have to make my Android tablet attempt to connect to the meter a few times before there's a successful connection, before the data starts rolling in. Tapping the tablet a few times before getting a connection isn't a big deal, except that it wastes a minute each time before you realize the request failed. The SwitchBot app is real nice. I like moving graphs, and it moves swiftly as a day's readings come in. The meter will save a huge amount of data if you don't connect for a long time. When you finally connect, the graph will slide along as the meter downloads its saved data up into the app. Practically, you can check out a lot of history whenever you finally get the chance to look it over. You can zoom in to an hour's graph, or more compressed to display a day's, week's, month's, year's. You can adjust ("calibrate") the SwitchBot app so its readings match the local thermometer/hygrometer. Good enough for government work. My dehumidifier can be adjusted in digital increments of 5% each. When I changed the adjustment from 45% to 40%, the humidity in the basement dropped from an almost constant 46% to an almost constant 43%. Just goes to show you. Well, it's only been a day, maybe it'll drop a couple more points over the next couple of days. A month or two later... Replaced antique cellphone with modern, compact, Google Pixel 8 cellphone with Android 14. When I go looking for SwitchBot data on Bluetooth, the connection hooks up fast, without me having to keep trying over and over. Surprisingly, the performance is much better than the tablet with Android 12, even though I'd expect the tablet to have a bigger antenna, etc. I don't think it's a matter of Android 14 being better than 12; I think simply the radio in the phone is better. But I don't know. Anyway, it proves that the SwitchBot can react quickly, given some good hardware talking to it. 4 months old... SwitchBot reports its battery is at 98%. My math is wanting, but... If 4 months used 2%, 100% will take 200 months, about 17 years. I'll let you know. On the very nice Android 12 tablet, 1 hour of data rolls in every 2 seconds. On the Pixel 8 phone with Android 14, the data rolls in so fast, it's hard to be accurate, but it looks like the data rolls in at 2 or 3 hours of data every second, about 4 or 5 times faster than the tablet. 11 months old... SwitchBot reports battery is at 89%. I got my SwitchBot for about $8. Ever since, the price has been $15. I'd have bought another two more, but I can't bring myself to do it. Wish they would run some intermittent $8 sales... I guess it's the Supply vs. Demand curve. Micro Economics 101. They discovered their product is more popular than they expected. Well, it works good.

Works well and now I can set my RV fridge and freezer setting and know what the cooling temperatures are.

So I just set up a Hub2, 4 Indoor Hydrometer Plus sensors, and a single outdoor Hydrometer sensor. Everything seems to be working. The temp sensors need 30 minutes to do some sort of self calibration when turned on for the very first time, so I waited for that and all the sensors seem to be pretty close to what my Thermostat says in the living room. I was then able to calibrate all the sensors to read the same. I have cloud service turned on for all the units, which I'm assuming means they are now connected to the Hub2 and visible in the app even when I'm not home, but I haven't tested that yet. I would know if I had proper instructions but more on that in a minute. So far, everything seems pretty great. Why the 3-star rating, you ask? 3 reasons. 1) The almost utter lack of instructions. The instructions say almost nothing about how to set anything up, nor do they give much (if any) info on what any of the buttons or settings are for. I mostly just had to download their app and wing it. Luckily, I'm tech-savvy, so I was able to stumble my way through it. Fortunately, once you're in the app, it does give you a few hints here and there that helped me get it set up a little more quickly. I've seen some pretty abysmal directions in my time, but this takes the cake. 2) There's no way to modify how the information on the home screen of the app is displayed. Including the Hub2, I have a total of 6 sensors running. The only info these sensors display is Temp and Humidity, but for some reason this is displayed in a format that takes up a huge amount of room on your phone screen, meaning you have to scroll to see anything past the first 3 sensors. (See attached pic). This is ridiculous given that the name of the sensor, the temp, and the humidity could all be displayed on a single line, thus allowing a person to see like 10–15 sensors all at the same time. Initially I thought there would be some way to change the display, kind of like you can for something like a weather app on your phone. You know how you can select how many tiles it takes up on your screen? That kind of thing, but there is not. They do have an "edit home screen" option, but they only thing it seems to let you do on that screen is move the tiles around, BUT they won't stay where you put them. You can't even change positions in the list on this screen. You'd think you would be able to, but there's a whole different menu and screen to change the display order, so I can't for the life of me figure out what the "edit home screen" option is even for. 3) When I was looking around for an indoor/outdoor thermometer set that I could access from anywhere via the web, this set struck me right away as something that might fit the bill. That being said, NOWHERE in the product description (or even when I asked on Amazon under both the indoor and outdoor thermometers) did I get an answer to "Are the outdoor sensors compatible with the Hub2 or the Hub-mini?". The title and the listing itself would seem to imply they are Bluetooth only. THEY ARE COMPATIBLE WITH THE HUBS FOR ANYONE IN THE FUTURE WONDERING!!! (It's compatible with, at least, the Hub2, for sure. I'm assuming with the older hubs and the mini also) I had to just buy all of this stuff in order to try for myself and see. Needless to say, I shouldn't have to do that. In fact, I only made the purchase because I was fairly confident they would be compatible, since all the other Switchbot products I saw on Amazon were compatible. If I wasn't pretty dang confident it would work, I'd have never ordered it just to try and see if it works and Switchbot would have missed a $135 sale, not to mention whatever I might spend on their other compatible products. If they all perform exceptionally, and I don't have any issues with any of them in a couple/few years I may come back and give it another star, but right now it gets 3 and one to grow on...

Great for monitoring refrigerator/freezer temperature. It is registering temperatures down to -9 F, not sure if it can go lower. Have to put the mini-hub fairly close to the refrigerators/freezers. We noticed that our new Frigidaire freezer is popping up in temperature for 45 minutes a day using this.

The 5-STAR review is for the product description. Here is what I wanted to accomplish: capture temperature at least every 10 minutes and upload to an app on my iPhone. That is all. The Product Description said that was what the Thermo-Hygrometer would do. For over 60 days and within over 300 feet from the phone. HA! I wasted time just trying to get the device to connect with my phone. The AI assistant is dumber than a rock. There are NO instructions that actually match the App: "look for '+' in upper right . . ." Not there. Looks like the App has been updated into useless. WHAT? Then there is the "We want your data so we can sell you some other stuff. DO NOT BUY THIS PRODUCT
