IP65 Indoor Outdoor Hygrometer Thermometer Wireless 3Packs, 100m Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, 2-Year Battery Life, Free Data Storage

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.

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.

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.

What I was looking for was a wireless temperature data logger to capture the temperature in my house in the Hall and also the corresponding temperature outside with a reasonably high sample rate 24x7. This was so that I could see the rate of heat loss from the house when the space heating is off and also the effectiveness of the space heating when on. I bought 2 of these sensors and placed one indoors adjacent to the Hall thermostat and another outside on the roof fascia board. They come with batteries fitted that are said the last for up to 2 yr and are waterproof for use internally or externally. The devices use bluetooth to transmit data from the sensor to a Switchbot phone app. The phone app is easy to download from Google Play or Apple Store and shows instantaneous temperature and relative humidity, and dew point as well as continuous time history plots of temperature versus time with a sample rate of about 15 minutes. The sensors come with clear instructions and are every easy to pair with the app via bluetooth and initially the use may find that the temperature and humidity readings appear high but the device has a self calibration mode on start-up and soon moderates to an accurate reading. In my case, the temperature took less than half an hour to coincide with the reading on my Hall thermostat. From there on the readings have been very reliable and the temperature time histories show the rise when the space heating comes on according to the time clock and Hall thermostat controls and the rate of decline when it goes off. The app also gives max and min temperature over the selected time period of day/week/month/year and the average. Recordings continue until you choose to reset the sensor in the app effectively to start afresh. You can also download the data for your own records. Correspondingly, the sensor/app records and displays relative humidity as a time series etc all exactly as for temperature. In summary, this is an excellent wireless sensor that does exactly what I was looking for. Anyone who wishes to data capture temperature and/or relative humidity 24x7 and view the time histories of these parameters graphically on a phone or tablet with the data transmitted from the sensor to the phone/tablet wirelessly over bluetooth should look at this device. They are good value for money.

I am using this outside in my greenhouse and it has flawlessly kept track of the temperature and humidity for the last few months. It was very easy to setup within the Switchbot app and the app then allows you to track the stats over time. I have no complaints about the app at all however I have incorporated it and monitor the temp/humidity instead within Home Assistant which also works just fine. The sensor connects via wifi to my router and as above the sensor is outside the house in my greenhouse. My router is upstairs on the same side as my garden where the greenhouse is and I've not had any problems at all with connectivity. I do have temperature/humidity sensors in each room within my home and before placing it outside, I did compare it with my other sensors and the readings see accurate on this device. I don't know how accurate the battery level is but it's still showing 100% after a few months of use - it does claim in the advertisement to have 2 years battery life. The device is well made and appears to be fully waterproof so I think it would indeed work without problem outside (not within a greenhouse etc.). For the price, this is a great item and I certainly would recommend.

The set up was really simple and the monitor is a very handy size. I bought it to take on holiday, as I was curious to know how warm it was while away. It’s been easy to use, reliable and, of course, super portable. The info I get on the app is interesting and it’s great that I don’t need a constant internet connection for it to work. I’ll also use it when I hibernate my tortoise over winter. Highly recommended.

Great looking little unit, well packaged and relatively easy to set up. I haven’t got a hub but for this it isn’t always required but you won’t be able to access the results remotely without it. Anyway, after a few hours, it stopped recording historic data. Got in touch with SwitchBot support, they were swift and helpful, batteries out (which are 100% still!), reset and started again. Did that a few times but it kept stopping recording and reporting the current temperature after a few hours although the app was still seeing the sensor, weird. Got back in touch with SwitchBot who are now sending me a replacement. The two stars are for the tech support guy ‘Jeffrey’ who was polite and helpful but let down by a poor product from the start, hopefully the replacement will work longer this time! Update one week later: Replacement arrived and worked as expected just a pity my original sensor didn’t! Great customer service. Rating increased to 4 stars!

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.

Returned. Bluetooth range not working for greenhouse location.

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.

Voici quelques semaines que je l'ai installée sans problème. Il fait parfaitement son job, facile à utiliser.

He comprado el termómetro básico SwitchBot Meter y estoy muy satisfecho con el producto. El embalaje está bien cuidado y el dispositivo llegó en perfectas condiciones. La puesta en marcha es muy sencilla: poner las pilas no tiene misterio (¡lo más difícil es abrir el paquete!) y, si se desea, se puede pasar el lazo del pequeño soporte para colgarlo fácilmente. Lo que puede resultar más complicado, especialmente si tienes varios dispositivos iguales, es saber cuál está detectando tu móvil durante el proceso de configuración. Si los códigos de identificación están impresos en algún lugar de cada aparato, no se distinguen de forma clara, lo que puede dificultar la identificación correcta en la app. En mi caso, actualmente tengo nueve SwitchBot Meter repartidos para monitorizar el calor y la humedad en una casa antigua, lo que me permite seguir con precisión cómo evolucionan las condiciones ambientales en diferentes estancias. El tamaño compacto permite colocarlo prácticamente en cualquier sitio y el diseño es discreto y moderno. El hecho de poder consultar todos los datos históricos en la app me parece muy útil. Además, el SwitchBot Meter se puede integrar fácilmente en un sistema domótico si se dispone de un Hub SwitchBot, almacenando los datos en la nube, recibiendo alertas y automatizando otros dispositivos. Para un producto tan sencillo, ofrece muchas posibilidades y funciona de manera fiable. Por último, me gustaría que el dispositivo ofreciera la opción de enviar las lecturas a la aplicación con mayor frecuencia, ya que el intervalo predeterminado es de diez minutos o más. Para ciertos usos, especialmente cuando hay cambios rápidos de temperatura o humedad, sería muy útil poder recibir actualizaciones en tiempo real o al menos cada pocos minutos. Por lo demás, cumple perfectamente con lo que promete y lo recomendaría sin dudar a quien busque un termómetro e higrómetro digital de calidad.
