SwitchBot IP65 Indoor Outdoor Hygrometer Thermometer Wireless, 100m Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, Free Data Storage Export, 2 Years Battery Life

I have been using my switchbot mini hub and thermometer hydrometers for about 3 weeks and I have to say I am impressed. I have found the system very easy to set-up and link to my wifi and the app and the meters and hub work seamlessly with my Alexa. The system has been amazing for keeping an eye on temperatures and humidity levels around my property. This is by far the best system I have used so far for ease of use, connectivity and reliabilty. The app seems to work well with no glitches and is easy to install, link to devices and use on the go. On the whole I would highly recommend this product and switchbot, and I would definately consider using other products made by this company for their quality and reliabilty. I would also like to mention Switchbot's excellent customer service and after sales communication.

I’ve been extremely impressed with these SwitchBot temperature and humidity sensors. I use several around a large caravan to monitor internal and external conditions, particularly during colder weather. The sensors are compact, easy to install and have proved extremely reliable. The real advantage, however, comes from connecting them to my SwitchBot Hub Mini 3e. I can monitor temperature and humidity remotely from my iPhone, examine historical graphs and compare readings from different locations. This has been invaluable for understanding how the caravan retains heat and managing its heating efficiently whilst protecting against frost. The app is intuitive, the information is clearly presented, and the ability to access historical data is particularly impressive. An excellent, well-designed system that offers far more functionality than you might initially expect. Highly recommended!

As a newcomer to Home Assistant, these SwitchBot sensors completely exceeded my expectations. Pairing and integrating all three into my setup was effortless—they were detected almost instantly and easily paired to shelly switches via passive BLE and have provided rock-solid, reliable data now for over a month. Having accurate, continuous climate monitoring across multiple rooms indoors and outdoors, linked to automatic provides fantastic potential. The 3-pack is good value, and the experience has convinced me to expand the ecosystem further—smart TRVs and more sensors are definitely next on my list. Highly recommended!

The first pack of three I ordered seemed OK BUT one of them was over reading the temperature by 20 degrees! A bit too much to calibrate out! Obviously they have been returned for a refund and I decided to take a punt on another set which arrived today. These are very good and having let them settle for 20 minutes or so on my window sill all three are matched within 0.1 degree C and 1% RH. They are very easy to setup, the case is compact and looks well made, from decent plastic, and they can be used free standing, attached via the supplied 3M adhesive pad or hung up using the supplied lanyard. Early days yet, I have not checked how far away from your phone you can get reliable readings, possibly not that far as they use Bluetooth Low Energy (BLE) profile but I will try that out shortly as I hope to use one of the sensors in the greenhouse. Overall very impressive as I was particularly interested in a device which shows the calculated dew point which these do along with loads of other information which can be in graph format apparently for the last 68 days chosen from a calendar - might have to wait for it to download from the sensor for a while? The only cons are that I did get a faulty product first time around and you have to load the "SwitchBot" app on your phone, from the Playstore, to actually use them although the app is very well implemented. This now means I have four different apps to cover these and various other devices although the majority of my devices use the TP-Link Tapo app (I was trying to standardise). It would be nice if the manufacturers got together and produced a common app for these things similar to Google Home, but hopefully much better as I find that to be very poor! Of course these devices CAN "talk" to Google BUT only if you purchase their Hub at considerable extra cost. The listing specifies that the Hub uses WiFi but I assume that is only for the Hub - Router connection whilst the Hub talks to the sensors via BLE? Depends how much value you place on being able to ask the question "Hey Google, what's the temperature in the greenhouse?" For me just tapping a couple of icons on my phone screen is easier (and silent) especially if Mr Google is in one of his obtuse modes today! The icing on the cake - when I got around to re-ordering this set the price had dropped by about £7! p.s. As I am typing this temperature variation between the sensors is now 0.3 degrees but they are still within very reasonable limits and in agreement with various other devices I have here.

I purchased another pack of switchBot IP65 Indoor Outdoor Hygrometer Thermometer Wireless, and I couldn't be more pleased with their performance. I initially bought it when it was 1st released and it's still working great. Here's my feedback based on my experience: Design and Build Quality The switchBot hygrometer thermometers are excellently designed with a compact and sleek profile. The IP65 rating ensures they are suitable for both indoor and outdoor use, providing peace of mind against dust and water ingress. The build quality feels sturdy and durable, perfect for various environments. Installation and Setup: Setting up these devices was a breeze. They come with a strong adhesive backing, allowing for easy attachment to any surface without the need for drilling or complicated tools. The wireless design means no messy cables, making them versatile for placement in different areas of my home and garden. Performance and Accuracy: One of the standout features is the accuracy of the temperature and humidity readings. I found them to be consistently precise, even in fluctuating weather conditions. This reliability is crucial for monitoring indoor climate control and ensuring optimal conditions for plants, pets, and household comfort. Connectivity and App Integration: The switchBot hygrometers connect seamlessly to the switchBot app via Bluetooth. The app provides real-time updates on temperature and humidity levels, historical data tracking, and customizable alerts. It's user-friendly and intuitive, enhancing the overall utility of these devices. Battery Life: Battery life has been impressive so far. Each unit operates on a single CR2032 coin cell battery, which lasts for several months before needing replacement. This efficiency is convenient and cost-effective. Overall Impressions: I am thoroughly impressed with the switchBot IP65 Indoor Outdoor Hygrometer Thermometer Wireless 3Packs. They offer exceptional value for money with their accurate readings, durable build, easy installation, and reliable connectivity. Whether you're monitoring your home environment, greenhouse, or outdoor spaces, these hygrometers are a fantastic choice. I highly recommend them for anyone looking to maintain precise control over temperature and humidity levels. If you're in the market for reliable hygrometer thermometers that perform exceptionally well indoors and outdoors, look no further than the switchBot IP65. They exceeded my expectations in every aspect and have become an indispensable part of my home monitoring setup. I wholeheartedly endorse these devices and would not hesitate to purchase them again for myself or recommend them to friends and family. Pros: - Accurate temperature and humidity readings - Durable and weather-resistant design (IP65) - Easy installation with adhesive backing - Long battery life - Seamless app integration Cons: - None observed so far - Maybe the bluetooth signal could be a little stronger to increase the range but overall it's all good enough Final Verdict: 5 stars without hesitation. These hygrometer thermometers deliver on their promises and more, making them a worthwhile investment for anyone prioritizing precise environmental monitoring.

Maybe I'm just lucky but the one I've received is working perfectly. Once I've got it, I compared the temp/humidity values it provided with 2 different Govee sensors and another no name one. They were all within 0.4–0.8°C each other at outside temp. around 17°C and 26°C. Humidity was a bit more different but that is Ok. This is good enough for me. I was not expecting (and need) 0.1–0.2°C resolution and accuracy. For that kind of accuracy you'll need to invest into something more substantial. I'm also not using it the "normal" way. I've built a small R-Pi weather station with the Enviro+ board and I'm using the Switchbot as a reference data source connected via Bluetooth and also correlating it with Open Weather Map's API. It has been working perfectly outdoors for a month and a half now and the battery has yet to drop from 100%. Note, The Bluetooth connection is only use once in every 15 minutes. I can imagine that if you are constantly monitoring it, that will keep the Bluetooth connection alive, in turn it will drain the battery much faster. Wireless communication, including Bluetooth requires a fair amount of power. I also use my phone occasionally which connects from about 4 meters from behind a brick wall without issues. So, all in all I'm very happy with it and will order another one for a different project soon.

Compact unit which we bought for our greenhouse. It works on Bluetooth. Customer service was very helpful and we got the Bot connected up to the App with little difficulty. The App allows us to read greenhouse temperature easily and accurately. Thanks

I have tried a few Bluetooth weather devices, and this Switchbot is the cheapest and best. Physically, its advantages over similar devices are that it uses standard batteries (2xAAA, supplied) rather than a semi-randomly chosen button battery, and that it is visibly waterproof - it is a smooth white plastic box and the battery compartment lid has a seal round it. Also, the nylon hanging loop is as new after two years outside and is far better than a hole in the back meant to go over a hook or a nail. I was surprised, for such a cheap device, to find that it supports firmware updates, as there was a notification in the app on the first Bluetooth LE connection. It updated in a couple of minutes from 0.4 to 0.5 - an odd version number for a released product - and, as is almost always the case now, there was nothing stating what the update fixed or improved. But the facility is important. In fact, there were four firmware updates in the first three months and the current version is 0.9, although there has not been a further update for over a year. The app is also updated every few weeks, and there is the option to try out beta versions. The Bluetooth signal is good - I can transfer data into the app from a room about 60 feet away with no issues. Caching is well implemented and only new readings are transferred unless you explicitly clear the cache from within the app; this greatly speeds up everything as the device quickly accumulates thousands of readings. When I got a new phone it took 20 minutes to transfer all the readings. Its accuracy is better than that of my old Bresser weather station, which cost several times as much but badly underestimated temperatures. The quoted accuracy (+ or -0.2C) is, in itself, accurate in my experience. Another Switchbot advantage, although it gets low ratings in Google Play (presumably through a combination of covering all Switchbot hardware, not necessarily as well as here, and user error when trying to work devices), is the app. It looks good unlike many similar apps, is simple to set up and use, and data export is easy - select a date range and readings are exported to a comma separated values file in a defined time step. Exporting a reading every minute gives a huge 1.7MB/month file, but exporting a reading every half hour amounts to 50KB/month. I can produce graphs very easily from the exported file - the big graph follows an import into Excel 2024 LTSC with no further changes to one of the standard charting types other than to colours and the other two graphs show what the app can display itself. The battery level remained at 100% for a long time and only fell to 48% after two years, so is longer than advertised (two years). I decided to replace standard alkaline batteries with lithium batteries, so may well get far over two years in the future. The Switchbot is an excellent data gatherer. If it could record barometric pressure as well as temperature and humidity, it would replace everything weather-related here. I use a second (ancient) Android phone to provide a semi-permanent display. A minor issue is that the instructions state that the temperature sensor is good to -20C, but the device is recommended only to be used at 5C or greater. It has been down to -6C, with whole days below 5C, and I have noted two missed readings in over a year, which were both when the temperature was well above 0C. Most impressive was that I discovered a bug when exporting. I raised a ticket in the app; there was a comment back about three days later that it was being "escalated to senior technical staff", then after six days there was a fix available in Google Play! That speed of response is otherwise unheard of in my experience, where technical comments are often not even acknowledged. As I had two other weather stations fail during the unpredictable weather (huge temperature and humidity fluctuations) in January 2026, I extended my "Switchbot estate" as the good build quality mentioned in the second paragraph matters ... a lot. This device was the only survivor. £15 (£11 with a coupon) is an absolute steal for something which would have cost many times that a few years ago for the same functionality and would certainly have been less robust and less easy to use.

Używam czujników od dwóch lat i mogę jasno stwierdzić, że to świetne gadżety, działają bezproblemowo i do tej pory nie wymieniłem baterii ani razu. Leżą na zewnątrz i wewnątrz lodówki, zapewniając mi stały, wyraźny obraz temperatury i poziomu wilgotności. Pomiar jest precyzyjny i niezawodny. Polecam te produkty.

Ho acquistato questo sensore per monitorare costantemente temperatura e umidità nel terrario delle mie dendrobates e fin dai primi utilizzi si è dimostrato un accessorio davvero indispensabile per ogni allevatore. L’installazione è semplice e le batterie sono già incluse, dettaglio sempre apprezzato perché permette di utilizzarlo subito senza acquisti aggiuntivi. Nel mio caso ho acquistato solo il sensore senza centralina/hub, quindi il funzionamento avviene tramite Bluetooth. È una cosa importante da sapere prima dell’acquisto: senza hub non si hanno le funzioni remote via Wi-Fi, ma per un controllo diretto e locale tramite app svolge comunque molto bene il suo lavoro. Uno degli aspetti che mi ha convinto di più è la precisione delle rilevazioni. Per chi gestisce terrari tropicali e specie sensibili come le dendrobates, avere dati affidabili su umidità e temperatura è fondamentale, e questo sensore mi ha dato riscontri coerenti e stabili nel tempo. App utile e lettura dei dati chiara, con un prodotto nel complesso compatto e poco invasivo all’interno del setup. In sintesi: sensore preciso, pratico e consigliato per il monitoraggio del terrario, tenendo presente che senza centralina funziona esclusivamente via Bluetooth.

Returned. Bluetooth range not working for greenhouse location.

Very easy to connect. Be aware that walls and other obstacles shortens the 120 m considerably. I have placed the one I bought in an underground potatoe cellar and can make readings above ground just outside of the cellar, which is fine for me, but should be considered, depending on your needs. However, I doubt that any other Blutooth product could do any better by far!

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.
