HT.w Smart Temperature Sensor & Humidity Sensor - Bluetooth Thermometer and Hygrometer with App Monitoring - Water Resistant Temperature and Humidity Monitor for RV, Basement, 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.

this product is excellent, very accurate and delivers a lot of data and the capabilities of notification and the reliability are amazing. I have now had these for over a year and I can tell you that they work, no issues with communication or anything else.

Nifty little tool. Using primarily for hatching chicken eggs as I questioned the accuracy on my nutureright 360 and ovabator incubator. I like the data plotting for average temp which is important. The app works great and is very easy to set up and use. I checked accuracy of the unit with a heavy ice bath and it read 31.7F after stabilizing around 15 minutes in. This is within the manufacturers specs of 0.36F. Its not an instant or quick read if thats was youre looking for it takes a few minutes to stabilize at its surrounding temps. Humidity seems to correlate with another hygrometer nearly exactly. Made in USA, would buy again if I find another simultaneous need.

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:🥶 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.🚨 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.📈 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.🙌 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.💡 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 – 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!

I don’t do many Amazon reviews but these sensors are great.My professional background is in the clinical lab and I’ve used many different monitoring sensors.I compared the sensors to calibrated reference instruments and these sensors were right on. The range is also great…much better than others I’ve used. Setup was also super easy.
