HT.w Smart Temperature Sensor & Humidity Sensor - Thermometer & Hygrometer w/App Monitoring - Water Resistant Temperature and Humidity Monitor w/Heat Index for RV, Fridge & More

These work great! I keep one in each freezer at home connected to the WiFi gateway (sold separately) and I can monitor from anywhere. When going on trips or travelling, it is great to know that your food stays frozen and safe in the event of a power outage or equipment failure. Only drawback to this system is if the internet or wifi go out in the house, you will lose connectivity - but if you are nearby, you can connect via bluetooth. Additionally, we have an RV and keep it next to the house, so we have some in there (fridge and freezer) and it can also connect to the home gateway. When we travel with the camper, you can use them on bluetooth if you are nearby. I highly recommend them, a great idea that really works well.!! Easy to setup and includes an app that is easy to navigate and you can set your own alerts for hi and low temp and humidity. Great product.

Although, I have not compared it for accuracy, it seems to be pretty sensitive to various factors that affect humidity and temperature. The minute to minute graphs that come with the app are super awesome. The web api allows you to superimpose the different sensors, which I wish I could do in the app, but awesome that there is one place I can go to see it. The SensorPush app is available for the iPhone and MacBook, which is cool to have access to readouts on my computer and phone. Connectivity seems normal for Bluetooth. And, one thing I really want to tout is the tech support. I got the gateway, which I recommend, so you can monitor temps and humidity on vacation to see if everything is going ok (e.g. prevent freezing of water pipes, keep humidity low to avoid mold, etc.) And I had some initial problems with syncing, duplicate sensors, etc. Tech support solved all my issues that seemed not possible from my end and even gave me some more insights about how to work the devices from my end. Highly recommend!

I don't do many reviews. I really only review really bad stuff or really great stuff. This is one great ones. Preface: I only really use the temperature monitoring features. 6 sensors and 2 gateways. Tl:dr Pros: Setup is stupid simple. Accurate (Plus the ability to calibrate the temperature up or down.) With a Gateway you get Push notifications, email alerts, and app alerts when a temperature or other readings are outside your custom range. Can also check temperatures anywhere you have internet. (with gateway) Also has a web based interface if you don't want to use the app. (with gateway) App shows a wide array of metrics and data and isn't sluggish in doing so. Realtime data trends. Save and view historical data/metrics Smart home/Assistant integration (with gateway) Cons: Price can be a factor here but look at it as an investment in your food preservation! Sensor could be a bit bigger to allow for stronger bluetooth signal. Backstory: Two upright freezers blew from a power overvoltage at night and we didn't notice. Ended up losing thousands of dollars of food. Since then I looked for a well built and, most importantly, ACCURATE and FUNCTIONAL way to monitor multiple freezers and refrigerators with push notifications. After going through a bunch of other sensors I got one of these and tried it for a few months. I was totally blown away. These sensors are very accurate and very responsive to temperature change. The app shows you all the data you could want with near realtime (to the minute) readings, trends, averages, etc all in an easy to read and intuitive interface. The push notifications are where these things turn to gold for me. When paired with a G1 Gateway from SensorPush you can access the data wherever you have internet! But the REAL plus is that you get push notifications, app alerts, and email alerts when a sensor reaches a custom temperature threshold. If I had that before my freezers blew I could have woken up and seen the notifications and then scrambled to save my food. I can't say how pleased I am with these sensors. I can honestly say that I feel better knowing that, should another catastrophe happen to my freezers, these sensors will alert me and I can have time to save my frozen things before they thaw. I will update my review as time goes on. Some of the freezers I have get really cold (as seen in the pictures) so I shall see how resilient they are!

I'm not often given to writing reviews, but in this instance I had to make an exception. For occupational and safety reasons, it is important for me to know early morning outdoor temperatures especially through the winter months. Over the years I've had so many so called weather stations with an outside sensor and an indoor read out. Mostly these have been next to useless, hardly ever making the claimed wireless connection irrespective of where they were placed. Looking for yet another solution, I came across SensorPush, never heard of them, no idea what they were about, or indeed if this would be the answer to the eternal problem. So I emailed the guys at SensorPush outlining my problem and what I needed to achieve. Allowing for the time difference, I got a prompt reply which from a customer service point of view was very encouraging, a brief further exchange of emails and they were able to confirm the unit most suitable for my needs, which I duly purchased there and then. I cannot begin to tell how impressed I am with this product, it is absolutely brilliant, having downloaded the app and paired with my phone, all I needed to do was position the sensor in an outdoor protected location (as advised by the guys at SensorPush) and this has worked flawlessly. I now have accurate outdoor readings from anywhere in the house (bluetooth range seems fine so far) I'm sure I will add additional internal sensors mostly for controlling humidity later in the year

Rapport qualité prix beaucoup trop cher, j’ai un autre appareil qui m’a coûté 25 € et qui donne les mêmes mesures. En plus la qualité du plastique laisse à désirer c’est beaucoup trop cher pour ce que ça vaut.

This sensor has been hanging off the outside of my camera bag or EDC bag, with me every single day for the last five years. I've only had the replace the surprisingly thick coin battery once since getting it. Finding the right battery may not be trivial as it is not a common size. Seems accurate and love the functionality of the iPhone app, being able to track and graph inside and outside temperatures over time. The durability has been impressive!

On est très satisfait du produit. On met l'appli, on met le boîtier ou on veut et on retrouve sur l'appli une courbe de température et une d'humidité. Fonctionne en Bluetooth mais l'appareil peut garder une vingtaine de jour les données en mémoire pour les Rapatrier dans le téléphone si vous n'étiez pas à côté. Mesures très précises !

Extremely reliable, precisely calibrated device. The Application works easily and clearly, and is easy to use. For convenient operation, it is worth buying the G1 WiFi Gateway. I can highly recommend this excellent tool.
