TempPro TP357 Bluetooth Hygrometer, Mini Room Thermometer with Alerts

⭐️⭐️⭐️⭐️⭐️ 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 👍

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.

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.

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

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.

Quite small (just over a couple of inches across), but still quite readable. Will stand up on a desk, or magnetically stick to a fridge/filing cabinet etc, or even wall hang. I bought 2 in the heatwave, and they agree with each other (which is better than others!). I didn't hold out much hope for the app, but actually it seems to work really well; bluetooth connects to both and lets me swap between the data from each of them easily.

We started with one of these a while ago as we have a greenhouse and wanted to see how cold it got at night (when we are asleep) and this seemed perfect as it can display records for the last 24hrs, week or year. We started using it around the house out of curiosity and found it so useful we have 3 of them around the house so we can see what is happening in different areas and also how certain factors affect the temperature in the house such as how much does having the dryer on heat up the rest of the house. Does the house stay cooler in the summer if we keep certain windows/doors closed or open. How accurate is our heating thermostat etc. We did have various items with a temperature readout on them which we had tried previously, with wildly varing results and they obviously only tell you what the temperature is when you look at them and using these are just so much easier and effective as well as accurate. You soon realise that something with a temperature guage is usually bad for getting anywhere near an accurate temperature. One digital temperature device for example would only move form 20C if the temperature changed by 3-4C which we had suspected as it only change from 20C if it seems really cold or really hot and we weren't sure if it was just a perception thing. We used it for example to test how effective our portable air con unit is and how large a space it can cool effectively. It can cool a room effectively and quickly and if we leave it on for around 4-5 hours it will additionally cool a whole floor by around 0.5C. After some experimenting we discovered that using a secondary fan to cycle the air from the room being cooled to the rest of the floor it can effectively cool the room it is in and also cool the whole floor by around 1C in about 30 minutes. Using these we also showed ourselves how the human body adapts to longer term temperature change and also why things like heat pumps won't work in real life applications. We often used to wonder if our boiler thermostat was faulty as we usualy have it set at 20C yet in the colder winter days it always felt cold and we would have to turn it up. The thermostat is fine, it always keeps the house at the set temperature, it is just in the winter the human body feels colder and the temperature needs to feel warmer for us to feel comfortable.

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.

Echt fijn ik heb er een stuk of 10 in huis alle kamers, schuur, auto. Geeft goed inzicht in temperatuur en luchtvochtigheid.

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.

Très satisfait à 1° près efficace on peut les contrôle par Bluetooth de son fauteuil j'en ai acheté pour toute mes pièces 👍

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.
