TP357 Bluetooth Hygrometer, Mini Room Thermometer with Alerts | Humidity Meter&Temperature Monitor with Smart App and Data Recording, Humidity Sensor for Room Office(Previously ThermoPro)

⭐️⭐️⭐️⭐️⭐️ 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 👍

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.

Working fine, and Bluetooth is great, display readability and tendency monitoring great too, only cons the battery doesn’t last for a lot of time, probably 1 month, so don’t install it really hide. I could change the battery size for an AA battery instead of an AAA.

For the first couple of days I would have given these units a 5 star rating - see the update below, it’s now 5 stars -They are neat, compact, accurate and work well. I’ve put one in the loft and one in the study that we don’t use much at the moment to check on the temp and humidity. Both work very well. The app is good and easy to use but the pairing keeps failing. Once you switch off the phone/ipad the pairing is lost. It’s easy to set up again but a but annoying to do it every day. Update - after seeing the above review the seller contacted me (via Amazon) and asked for the details of the problem. The next day they sent me a message to say the app had been updated and if I deleted the app and reloaded it the problem should be sorted, and it was! The units are neat, compact, well made and accurate. The app is very user friendly and actually looks good too. I’ve switched off both the phone and iPad several times, including overnight, and the app pairs with the units straight away when switched back on, very pleased and I will now be buying another three units. This is what customer service should be, if I could give six starts I would.

I'm tube fed so keeping my feeds at a cool room temp has always been a very stressful time in the english summer, these little thermometers are great at logging the temps and easily reading them on my phone so i dont have to keep opening the cupboard door to check the temp which then makes it hotter inside! wish i had searched for these years ago. amazing little things

I needed a simple - temp and humidity data logger after my others failed. These are small, compact easy to read. Download the software from the app store and in minutes you are reading data on your phone. Can connect multiple devices and download data. Im really impressed. Use data loggers a lot and these are a cost effective alternative for low risk environments.

I bought the set of three. I have checked the data on the app a handful of times and liked the way it displayed it. I recently got a dehumidifier so I thought I’d check the before and after setup. When I checked on the app last night, they all had a full battery logo. This morning one showed no data annd when I went upstairs to the device I saw that it wasn’t working due to the battery being flat. The two others still show a full battery logo but now I know that isn’t a reliable indicator. The battery lasted 19 days. I will replace it with a rechargeable one and see how that holds up. Nifty device but if I’m having to change the batteries every 20 days then it’s not at all going to be handy to monitor and keep up with or fit for purpose for monitoring room temperatures throughout the house in the heat. This happened the day after the Amazon return window closed. I will edit the update with more info in a few months time.

Excellent little thermometer/hygrometer! So impressed with the first one, I bought a second. Ideal to monitor home temperature. I've also checked refrigerator temperature too. No problem with Bluetooth range/reception, even in the fridge. Graphs provide good graphical information, with time period easily selectable. I've not had any issues with battery life like some have reported - still using the original battery supplied 4 months later and battery indicator still showing good charge.

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.

non potrei essere più felice della mia scelta. Questo strumento è stato davvero un acquisto vantaggioso e ha reso il monitoraggio della temperatura degli ambienti un'esperienza estremamente semplice e precisa. Una delle caratteristiche che mi ha impressionato di più è la sua connessione al cellulare. Questa funzione rende tutto incredibilmente comodo poiché posso controllare e visualizzare le letture direttamente sul mio smartphone tramite un'app dedicata. La facilità con cui ho potuto sincronizzare il termometro al telefono è stata sorprendente, e ora posso tenere traccia delle variazioni di temperatura ovunque mi trovi, senza dover essere fisicamente vicino al dispositivo (nel raggio di 50 metri). Inoltre, devo sottolineare l'elevata precisione delle misurazioni. Ho confrontato le letture del termometro con altre fonti e sono rimasto piacevolmente sorpreso dal fatto che fossero sempre coerenti e accurate. L'applicazione collegata al termometro è davvero ben fatta. L'interfaccia è intuitiva, facile da navigare e offre una panoramica chiara delle letture passate. Ho apprezzato particolarmente la possibilità di impostare notifiche personalizzate o allarmi, così posso essere avvisato quando la temperatura supera o scende al di sotto di determinati valori.

Klein en praktisch. Batterijen er in, app installeren en je kan direct aan de slag.

Update am 03.07.2026: Die mitgelieferten Batterien reichte bei uns für genau 3 Monate, dann waren die 3 Geräte aus. So hat man ein ungefähres Bild des Energieverbrauches. Je nach Batterie kann das natürlich variieren. __________ Rezension: Wir haben das 3er-Set mit Display für verschiedene Räume in unserem Haus gekauft. Durch die Bluetooth-Funktion lassen sich die Messwerte inklusive Verlaufsgrafik bequem über die ThermoPro-App auslesen. Hauptsächlich haben wir die Geräte über Bluetooth in unser Smarthome-System (Home Assistant) integriert. Dafür gibt es dort sogar eine eigene Integration. Wir nutzen die Geräte hauptsächlich zur Schimmelprävention in unserem Neubau. 👍 Was uns gefällt: --> Gutes Preis-Leistungs-Verhältnis --> Legt man die Geräte nebeneinander, stimmen die Messwerte sehr gut überein --> Praktische Bluetooth-Kopplungsfunktion --> Die Geräte speichern die Daten und übertragen sie später an die App – dadurch entsteht ein lückenloser Verlauf --> Ausklappbarer Aufsteller auf der Rückseite --> Magnet zur einfachen Befestigung auf der Rückseite --> Das Display lässt sich gut ablesen --> Batterien sind bereits im Lieferumfang enthalten --> Sie sind sehr dezent und stören nicht die Optik im Raum ⚖ Neutral: --> Wer die App nutzt, sollte sich datenschutztechnisch informieren. Die App benötigt unter anderem den Standortzugriff, damit die Bluetooth-Funktion genutzt werden kann --> Wer hauptsächlich ein Gerät zum direkten Ablesen sucht, sollte sich eventuell eine größere Version anschauen --> Die Aktualisierung der Daten in der App ist etwas träge, im Alltag für uns aber noch absolut akzeptabel 👎 Was uns negativ aufgefallen ist: --> Ein kleines Manko ist, dass der Bluetooth-Empfang zwischen verschiedenen Etagen nicht besonders stark ist. Dadurch muss man teilweise näher an die Geräte herangehen, damit die Daten zuverlässig synchronisiert werden. Im Smarthome-System fällt das allerdings kaum auf, wenn man mehrere Empfänger nutzt. 💡 Tipp: Wer bereits ein Smarthome-System zu Hause nutzt, sollte prüfen, ob sich die Geräte dort integrieren lassen. Gerade in Verbindung mit Home Assistant ist das im Alltag wirklich praktisch und erweitert die Einsatzmöglichkeiten deutlich. 🏁 Zusammenfassung: Insgesamt ein praktisches und zuverlässiges Thermo-/Hygrometer-Set mit gutem Preis-Leistungs-Verhältnis. Besonders überzeugt haben uns die zuverlässigen Messwerte, die Speicherfunktion sowie die Möglichkeit der Integration ins Smarthome. Auch zur Schimmelprävention im Neubau sind die Geräte für uns sehr hilfreich. Kleine Schwächen gibt es beim Bluetooth-Empfang über mehrere Etagen hinweg sowie bei der etwas trägen Aktualisierung in der App. Für den normalen Einsatz im Haus sind die Geräte aus unserer Sicht aber absolut empfehlenswert.
