Excellent Bluetooth thermostats
⭐️⭐️⭐️⭐️⭐️ Excellent indoor thermometers – smart, accurate, and super easy to use I bought the ThermoPro TP357 (pack of 3) to monitor temperature and humidity in different rooms, and I’m genuinely impressed. The Bluetooth connection to my phone is seamless — the app pairs quickly and stays connected without any hassle. Being able to check readings straight from my phone is incredibly convenient, especially when the sensors are in different rooms. What really stands out is how much useful information they provide. You get clear temperature and humidity readings, history tracking, and min/max records, all laid out in a clean, easy-to-understand app. The displays on the units themselves are also bright and easy to read at a glance. They’re very easy to set up and use, even if you’re not particularly tech-savvy. Just pop in the batteries, pair them once, and that’s it — they just work. Overall, these feel accurate, reliable, and well-built, and having three in the pack makes them great value for money. Perfect for monitoring living spaces, bedrooms, grow areas, or anywhere you want to keep an eye on indoor conditions. Highly recommended 👍

Great thermometer. Exceptional quality. Superb phone app.
Bought a pack of 3. They work great, quality is excellent and are super simple to setup. Download the refreshingly good dedicate app to your phone, which provides clear readings and customisable history of temp and humidity. Each thermometer can be individually named in the app. The data can be conveniently exported from the app.

Great for the price.
Lightweight, easy to use and link with app. Battery dies quickly (3 months) especially with supplied batteries. Invest in good quality/long life batteries and this really helps extend time between changes. App has some bugs which cause an occasional restart to be required but proves tracking data reliably.

Works exactly as it says it will.
Bought to keep track of temp in my camper during the summer, in the event that I have to leave my boys alone while, i.e. I have to nip into a shop that won't allow dogs. It connected straight to my phone via the free app and works really well. You can set an alarm to go off on the phone if the temp or humidity rises above the level that you set. I don't envisage using it much tbh, but, being a belt and braces person, it'll put my mind at ease, along with the 3 fans, bowls of water, and cooling mats we already have in the van.

Spot-on readings and stylish design—a must-have indoor thermometer
This ThermoPro TP357 room thermometer has been an absolute delight to use. Setup was a breeze—simply insert the batteries, place it on your shelf or stick it to the wall with the built-in stand or magnet, and you’re ready to go. The crisp LCD display updates in real time, showing temperature and humidity with pinpoint accuracy, so I always know exactly how comfortable my space is. Functionally, it’s superb: the clear numerical readout is easy to read at a glance, and the humidity indicator helps me adjust my dehumidifier or humidifier precisely. The compact, minimalist design looks sleek on any desk or countertop, and the sturdy plastic housing feels durable enough to survive daily knocks without the slightest wobble. In terms of value for money, it’s hard to beat—affordable yet delivers professional-grade performance. I’ve been using it every single day without fail, and it’s never missed a beat. I’d buy this again without hesitation and wholeheartedly recommend it to anyone looking for an easy-to-install, reliable, and aesthetically pleasing way to keep track of indoor climate.

OK product but BEWARE very poor battery life!!
These work fine and do what they say on the tin. However I have two minor gripes - firstly, it's a shame that they don't feed into Apple's Home ecosystem and you can only view the data in the dedicated app for them. Secondly, and more importantly, these devices EAT through batteries. I'm not really sure what's going on with them but 1 AAA battery barely lasts a month. Quite often I found myself looking at a blank display in disbelief that the battery had died so quickly! In the end, I have stopped using them simply down to the cost of constantly having to buy new packs of batteries. Shame really....

Good bluetooth temp meter. iPhone app works very easily. Battery lasted 5-6 weeks (only...)
I like the bluetooth function where my iPhone app can just pull the data. I use for my cabin hut indoor and outdoor. So I can monitor the overall temperature during the day/week. It helps to understand how the heating indoor is working, especially knowing how much it is affected by the outdoor temp. Battery: it just ran out. I started 7 jan and ran out 25 feb (for both units with the supplied AAA battery). So it seems like 5-6 weeks with every couple of days syncing with my app. It's a bit short, I plan to try to use 'better' AAA battery and see whether that makes a change or not. The downside is that it doesn't shows very well when the battery actually runs out. The temps seems to be good enough, it is similar to my other digital temperature meters that is part of my digital clock. The humidity and heat index seems unnecessary for my use case.

Bayılıyorum bu ürüne. Mükemmel. Köpeğimin uyuduğu yerin ısısını kontrol edebiliyorum. Wifi bağlantısı olmasını isterdim, iş yerindeyken sıcaklığı ölçmek harika olurdu. Geriye dönük ısı ortalaması vermesi çok güzel bir özellik. Isının düştüğü veya arttığı saatleri, günleri, haftaları görebiliyorsunuz.

He comprado el pack de dos (que vienen en blanco como en la foto) y también el que viene uno sólo (que es blanco y plateado satinado). Viene con pilas AAA en todo caso. El "cacharrito" funciona increíblemente bien y preciso (comprobado con varias soluciones distintas, la precisión en los míos es buena). Los tres marcan lo mismo, aunque la sensibilidad del sensor no es la misma en todos los aparatos, dependerá de cada unidad ya que depende de la electrónica que le haya tocado a cada uno (se nota en la gráfica, arroja más inestabilidad el higrómetro por ejemplo, o responde con más rapidez a los cambios de temperatura). La app se sencilla y perfecta. Los sensores conectan perfectamente rápido y se sincronizan en un momento. Te guarda los datos que haya registrado hasta entonces, con lo que puedes conectarlo una vez al mes y "estudiar" los cambios de temperatura porque te lo descarga todo a la app en un momento y ya tu visualizas lo que quieras, por día, semana, etc. Las ultimas 24h las registra practicamente cada minuto. El alcance dudo que sea los 80 metros que anuncian pero no es malo. Cuanto más lejos te pongas, mas lento conecta y descarga datos, como es lógico. El inconveniente que existe, que no es de la app sino de las maravillosas políticas de Google Play, es que OBLIGA a tener el GPS activado junto al bluetooth, cosa que cada vez todas las app van implementando. Es lo único negativo que le veo. FakeGPS.......ejem Por lo demás, practicidad, precisión, fiabilidad de la app, facilidad de lectura de datos, y calidad/precio, un auténtico 10/10. REVIEW NO COMPRADA, por cierto.
