SensorPush HT1 Smart Temperature Sensor & Humidity Sensor - Thermometer & Hygrometer w/App Monitoring - Indoor/Outdoor Temperature and Humidity Monitor w/Heat Index for RV, Fridge & More

(April 2019, 2 YEAR update! - Both sensors are still going strong, with a battery voltage of around 2.8 volts (I thought the battery lasted only 1 year? double that, and no sign of low battery). One's in the work office, and one's in my bedroom, over 600,000 readings for each. The app works fine with this much data on the Android system, and the CSV files export fine into Excel. NO crashes, NO needing to remove/insert the battery, not once, The Android app's never crashed. These ARE expensive, but I got what I paid for, and they do that very very well.) The device is simple to get started with - you download the App for Android, or iPhone, run it, and drop the thermometer block on your screen for a few seconds. That's it. Whenever you open the program, it reads all the temperatures and humidities that were collected since the last sync up. There's a new "Sync station" that picks up all your devices temperatures, and sends them to the gadgets website - where you can see them. It uses your existing WiFi network to send the data to the website, and the Low Energy Bluetooth connection between the WiFi and gadget. Info (pros): The battery lasts 1 YEAR, and can be replaced easily (no screws, just a plastic card like a credit card). The device can store AT LEAST 20 days of temperature and humidity - MORE if the temp doesn't change often, as it only stores temp changes and their date/time. You can CALIBRATE the device (instructions on the website). You can EXPORT all the readings your phone has picked up as an Excel compatible CSV file. You can give each sensor a name. The syncing distance is as good as claimed - it syncs across my house. (Cons): Temperatures are lost when it's re-calibrated. £50 at time of this review... Oww! . (But if you want "It just works!" - this is the device for you) The device IS NOT waterproof. But you can put it in a baggie. No direct-to-PC syncing.(For devices scattered around the house for example)

I bought this sensor nearly 2 years ago for indoor use, because I wanted to see the trends in temperature and humidity in a specific room. It has served me well ever since - no battery change required yet. It's very simple to set up and use, and I'll certainly be buying more if/when my data logging needs expand. I didn't have to perform any calibration, as occasional tests against high accuracy equipment showed me it was quite good at its job without it. One downside is that the phone won't connect to the sensor automatically unless you open the app (presumably to save battery life), so I do have a gap over the summer when I forgot about it for a few months - the backlog of something more than 20 days helped bridge that, but wasn't quite enough. Still, that's my own fault for forgetting, not the product's! They made the WiFi Gateway partly to avoid data loss, but I've decided my need for that is not great enough at this point. Pros: - easy to set up - easy to use - accurate - long life - good app interface, allows for viewing of all the data (I know a cheaper similar product only shows up to the last 100 days, for example, which is just... strange?) - 20 day internal backlog is pretty good (again, the cheaper similar product I've seen needs to connect daily) - can export data to CSV files (and view with your favourite spreadsheet tool) Cons: - can lose data if you forget about it for too long (unless you also have the WiFi Gateway) - not waterproof (so you probably want something more robust for outdoor use) - not the cheapest

Great product. I ordered one and I'm going to order a second. Works right out of the box (as soon as you download the app). I love being able to see the data on a graph. I have two suggestions for improvement with the app though, which are: 1) Able to scan the data left and right. For example, if I'm looking at the data from the last hour, but want to see the data from the previous hour, it seems intuitive to simply swipe horizontally across to see it. Currently though, if I want to view this data, I either have to select the 24 hour viewing mode (which now greatly compresses that information) or import it onto my computer. 2) Provide the option to see the Absolute Humidity (in addition to the Relative Humidity). For example, when the heat comes on, the relative humidity goes down, since the air can now hold more water, but the amount of water in the air hasn't changed. Perhaps you could double tap the Relative Humidity Graph, which could flip the graph around to present the absolute humidity instead, and vice versa. Anyway, as I said, fantastic product. I highly recommend one. I've shown a few friends and they were impressed too.

Bought this to monitor humidity and temperature for my mandolin in its hard case. It's ideal. Setup was a breeze ( both on my iPad and my android phone); readings very accurate (compared to a recently fully calibrated Kestrel weather device). The Bluetooth range is impressive. Compact size is great for an instrument case. The battery supposedly should last about a year, so no recharging hassles, no sockets to get damaged or cables to lose, and battery replacement looks easy. The app is clear and elegant. There is a facility to email yourself a Csv file of all data for use in a spreadsheet. There are cheaper options for this type of monitoring, but this is top notch. Apparently there are plans for a wifi bridge, which might be useful for some users who need to monitor when away from the sensor location (the device itself retains about 2 weeks worth of data). When Amazon was out of stock of this item, I contacted SensorPush and they got back to me immediately with accurate information about the restock date: so all the signs of excellent customer service. I will update in a few months time on long term performance, but for now I am completely satisfied.

The easiest sensor I have ever linked to my phone's Bluetooth and used. Simply tap the add device and find the model type and add; an image of the adding sensor pops up onscreen upon which you set the sensor to pair- done. Super easy! Chose these over the competition since these didn't require a cord to pass out the door to the sensor, it is all wireless for about the same price as the others. In the first month of use it saved our household an entire refrigerator of spoiled food. The fridge stopped cooling one night and the notifications from the app alerted us to the problem just as the temperature got above 44 degrees inside. We were able to quickly move everything into another fridge before it all went bad. Easily paid for itself that night! We now have 5 separate SensorPush sensors- 1 HT1, 4 HTP.wx's, and one Base Station. The app is super easy and intuitive too, with easy-to-read charts or tables that track the temps and humidity of every connected sensor all at once. Great products will definitely buy again and have recommended to all my friends!

good

Configurazione semplicissima, connessione senza problemi, misurazioni attendibili, insomma un ottimo prodotto. L'app potrebbe essere migliorabile, in particolare per la possibilità di zoomare di cui anche altri hanno lamentato la mancanza, e il refresh dei dati che non è sempre immediato, ma il customer care (tempestivo e disponibile) mi ha confermato che ci saranno evoluzioni. In ogni caso, volendo informazioni dettagliate, c'è una comodissima funzionalità di export dei dati che permette di leggere tutte le singole rilevazioni in formato tabellare (e, volendo, quindi, costruire grafici personalizzati con un qualsiasi foglio elettronico tipo Excel) Il costo non è irrisorio, ma ciò che mi ha convinto è che si tratta di un sistema espandibile all'infinito e gradualmente: la maggior parte delle stazioni meteo non professionali supportano al massimo 3 sensori ed hanno comunque un costo significativo per fornire i dati su uno schermo nella maggior parte dei casi LCD o in qualche caso a colori ma comunque piccolo e primitivo, mentre questo sistema consente di partire con un solo sensore e già beneficiare dello schermo di uno smartphone (o di un laptop esportando i dati), e poi via via aggiungerne altri secondo necessità, eventualmente corredati dal modulo web per poter accedere direttamente da laptop anche da remoto. Se si mettono insieme queste considerazioni con il fatto che il sensore è preciso, affidabile e compatto, dal mio punto di vista è difficile pensare a una soluzione migliore

Capteur acheté pour contrôler la température et l'hygrométrie dans ma cave à vins électrique. Matériel très compact donc facile à glisser dans ma cave. Pour garantir la précision des données, il est nécessaire d'etalonner le capteur ; opération effectuée à l'aide du kit "HYGROMETER Calibration" de la marque Boveda 75% RH. Extrêmement efficace et facile d'utilisation, ce capteur fonctionne seul en liaison Bluetooth (obligé d'être à proximité du capteur pour relever les informations) ou via un module Sensorpush WiFi G1 (100,00 € en sus) pour contrôler les valeurs de n'importe où. Ces dernières sont enregistrer dans l'application Sensorpush et peuvent être extraites au format CSV pour les intégrer à Excel par exemple. En résumé, le produit coûte un certain prix mais à l'usage, ça en vaut la peine. Je suis très satisfait de mon achat, je viens d'investir dans un second capteur pour ma deuxième cave ainsi que le module WiFi pour être alerté d'éventuels défauts sur mon portable, il serait dommage d'altérer plusieurs bonnes bouteilles pour un problème de température ou pire, d'hygrometrie.

I use these data logging thermo-hygrometers to monitor and record jobsite conditions for the installation of temperature and humidity sensitive building materials. The accuracy and functionality of these units in the hands of somebody who understands them is fantastic for the price-point. Previous similar tools that I have used cost upwards of $300 and don't have replaceable batteries. The alerts and reporting have saved us from several failures and our customers love them. I use the reports for warranty-claim validation as well. Others have commented on a lack of accuracy and insufficient calibration range. It should be noted that temp/rH sensing elements are sensitive electronics and could arrive damaged and that they do not last forever. When I receive them and set them up, I check their calibration against my $700 thermo-hygrometer and they are almost always within 1% rH and 2 degree F when I get them out of the box. The last jobsite I setup, I had to adjust the rH about 4% to calibrate the SensorPush, but that was easily done. Nothing is perfect and sensitive electronics can fail, but I highly recommend these units!
