The SensorPush HT.w Water-Resistant Indoor/Outdoor Humidity / Temperature Smart Sensor with Alerts




Your favorite Humidity and Temperature Smart Sensor just got even better! The HT.w uses the same outstanding mobile applications as the HT1 but now features:
Even better accuracy: Uses an updated digital humidity/temperature sensor, with a typical accuracy of ±2%RH, ±0.2°C / 0.36°F
Water resistance: Sensor membrane and o-ring seals provide a durable, splash and rain proof design
Easy battery changes: Easy-change battery cap, making the infrequent battery changes a breeze
Even longer battery life: Battery life now estimated at over 2 years in normal conditions
Made in USA: Perhaps best of all, they’re designed, supported, and now manufactured right here in America
And of course, like all SensorPush sensors, the HT.w can measure, record, and alert on dewpoint and VPD (vapor pressure deficit), and works seamlessly with the G1 WiFi Gateway for remote access.
You’re busy. You know that proper temperature and humidity are important. But who has time for constant monitoring of conditions in the places they matter most, like refrigerators, guitar cases, humidors, attics, basements and crawlspaces?
SensorPush is the answer. Our Smart Sensors are compact and easy to use. They work with painstakingly designed mobile apps that not only make you love using them, but also require as little use as possible. It takes just a few moments to install our free app and pair your first sensor. After that, it’s up to you.
If you love data, SensorPush has it, beautifully graphed in-app or easily exported to CSV for use in software like MS Excel. Either way, you’ll be amazed by what you can learn from a complete history of minute-by-minute updates.
Or, sit back and relax. SensorPush is constantly monitoring conditions, even while you’re sleeping or away. Upon your return, you’ll be promptly alerted of any issues once data is downloaded via Bluetooth. If you’re going to be away for awhile, the sensor always maintains the most recent 45 days of data on board. For maximum peace of mind, add the SensorPush G1 WiFi Gateway for constant access and alerts from anywhere, via the Internet.

Review after 2 years – Still very happy!!! and 1 for an upright freezer) and a SensorPush wi-fi gateway so I could monitor status when we are travelling.These devices have already paid for themselves when my 3 year old refrigerator was acting up. I had no idea there was a problem with the fridge until I got a warning from Sensor Push that the temp had risen above above the alarm threshold I had configured in the App. I was able to monitor the temps in the fridge, confirm I did have a problem, and move the contents to another fridge before any food was lost or spoiled and this likely saved me several hundred dollars in lost food.Fast forward to May 2023, one of the sensors stopped working. After replacing the battery and trying to reset the sensor I reached out to the Sensor Push service for help. They quickly determined that the sensor had failed and the next day they sent me a replacement.I am very happy with the sensors, Wi-Fi Gateway, and the overall functionality of the App.Super happy with the recent response from their support team. Thank you again Jonathan C. at SensorPush. ðð½ðð½I have frequently recommended this product to my friends and family and will definitely continue to do so in the future.
I first purchased this product in July 2021 to put in a small fridge used solely for temperature sensitive medications. I was so happy with the product that I subsequently purchased 4 more sensors (3 for my kitchen fridge
After setup, it is so useful and quick to access!
Easy to setup, just follow the instructions. We use it to monitor for aquarium leaks, just placed it under the tank. Instant alarm.
Not for Mushroom Growing
This is a great sensor. However, it will not work in a mushroom grow tent where spores may circulate. The spores will eventually clog the sensor and cause it to misread after 1-2 months.Attached are the pictures of setup, accurate reading, and misreading.
Hard to improve
Syncs fast to phGreat Blue tooth rangeGood appMaybe they could include some 2 sided 3m tape but itâs an excellent product that does exactly what is says it will do
Product seems to work
The product was extremely easy to set up and seems to work really good. I’m using it in my drying tent and it saves me from going I’m there and opening my tent just to check the temps so it’s a life saver and worth the money.
Best so far
This has been the best sensor I have had. Very accurate and with great application functionality. Is also very portable
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:drPros: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/metricsSmart 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!
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 !
I use this product to monitor temperature & humidity in parked campervan, shed, etc. Product is accurate & works well, with good bluetooth connectivity with remote smartphone app. Latest version has much improved battery access for annual battery change. This product is rather expensive, but it is well built, very accurate, and very small – so easy to place
measuring the temperature outside and in the refrigerator
I can’t express how relieved I am to have discovered the SensorPush Wireless Thermometer. This device has proven to be an absolute game-changer for my business, and here’s why:𥶠Peace of Mind in a Crisis: Recently, we had a walk-in freezer breakdown, and it was nothing short of a nightmare. However, since incorporating the SensorPush into our freezer monitoring system, I no longer lose sleep over such incidents. The ability to monitor temperature from my phone has been a game-changer.ð¨ Immediate Temperature Alerts: With the SensorPush, I can effortlessly monitor temperature levels and receive instant notifications should they stray beyond the safe range. This is invaluable in our maintenance routines. For instance, I’ve set an alert at the highest temperature reached during the defrost cycle, which occurs every 6 hours. This not only ensures that our goods remain safe but also serves as a reliable indicator of the proper functioning of our defrost timer.ð Valuable Historical Data: Having access to historical temperature and humidity data is invaluable. It is helping us track trends, identify issues, and maintain optimal conditions for our products.ð Indispensable Addition: I can’t help but wonder how I managed without the SensorPush before. It has become an indispensable tool for my business, and I can’t imagine running my operation without it.ð¡ No Monthly Fees: One of the most significant advantages of the SensorPush is that it doesn’t come with any pesky monthly fees. You simply purchase the sensor unit, set up the Wi-Fi gateway, and install the app on your phone â it’s incredibly user-friendly.I’m so impressed with the SensorPush Thermometer that I plan to install it in all of my freezers. The peace of mind it brings, coupled with its ease of use and affordability (no monthly fees!), make it a must-have for anyone who needs reliable temperature monitoring. Whether you’re a business owner or just someone who wants to keep an eye on temperature and humidity, this device is a true game-changer. I wholeheartedly recommend it!
