Smart Wireless Temperature / Humidity Sensor Wide Range (-22 to 158 degrees) for Freezer Fridge Monitoring Pet Cage/Tank Monitoring Smartphone Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included

After losing an entire freezer of meat, I wish I bought it before. I can see Temps any time and get an alert if it gets warm.

We have a lot of meat in our freezer and this is a great tool to monitor and be alerted if the temp gets too high.Sometimes those kids forget to close it all the way or if the power goes out in the garage and we dont know it. Plus if you are out of town, someone could come by and save all your frozen stuff for you. Set up was easy as long as you plug it straight into the router. Did not try the wifi method.

I read the reviews for this and some of them were unfavorable. What I really wanted this for was just to keep a track of the temperature for my freezer chest and garage fridge. Humidity isn’t really my concern. It is great for the purpose I bought it for. Instructions were super easy, navigation of the app is easy and it alerts me if my freezers go above a certain temperature. I would recommend it.

Bought to monitor the temperature of our pump house. A small cinder block building separate from the house. The sensor has no trouble staying connected to the hub inside the house. Battery lasts a little over a year, even in the remote building through multiple walls. I am very impressed.

Using LoRa (long range wifi) this works very well. I have one sensor in my fridge and the signal easily gets through the fridge walls and to the hub 3 rooms away. The alerts are sent to email and/or phone by way of the hub. Set up was easy. The app assigns a widget to each sensor but oddly doesnt label each widget with the name that you assign to each sensor in the set up routine. But thats minor and you can see which sensor name is assigned by choosing a label in the app. Very cool. Now I can see when the fridge door is kept open too long by the wife, ha ha!

This product a bit confusing to install. But the extra time it took my husband to install is worth confidence in our 2 freezers accurate operation. We freeze fresh garden veggies and our summer salmon catch and a new beef. A product we are very happy to have and satisfied with absolutely.

My immediate need was an alarm for a garage freezer, which is an older freezer and I had become aware that if we have a breakdown issue, could lose several dollars of food products. Simple audio alarms were not an option because of the distance of the de-attached garage from the house. Plus there are days when I do not even go out to the garage to hear an audio alarm. And I was concerned about relying on wi-fi shown on other systems. I was suspect about the quality from my router wi-fi signal to the garage and a sensor inside the freezer and then back to smartphone. The YoSmart and the Lora tech works extremely well, as advertised. I have a sensing unit in my garage freezer and get alerts on my email (text and Alexa are also options ) when the temp goes in/out of the range that I have set. As a new user I needed the YoSmart Hub as well and the package I ordered came with the Hub and two temp/humidity sensors. The second sensor is used in our inhouse frig. Since these worked so well, I have purchased a motion sensor and attached inside mailbox to alert to when postman opens and closes door, to alert me with an email when I have mail. And I purchased a third temp/humidity sensor and I am using it in the attic to monitor temperature and humidity. We have an automatic attic fan that comes on & off with a mechanical setting of temp and humidity. With the YoSmart sensor in the attic, I will be able to see the range of conditions in the attic as the weather changes. And with those changes I will then make setting adjustments on the automatic attic fan. In our area of the world, weather is full extremes in all Seasons and I believe the additional information provided by the sensor will help me make better adjustments on the fan and in turn keep the attic temp & humidity under control. Set up on the Hub and the sensors is a snap and instructions are very clear. Since the Hub is connected to the Internet, sensors can be monitored outside the home, via smartphone. Very pleased with this product - looking for other applications in and around our home.

Smart Wireless Temperature / Humidity Sensor Wide Range: $59.99 at the time of review We have had a freezer in our garage for a number of years. Unfortunately there have been a couple of different times over those years where the door was left cracked open or the circuit breaker blew and lost some or even all of our frozen food. So I finally decided to get a wireless sensor to alert me to high temperatures. *What I liked*: This is a complete kit using a proprietary wireless connection between the hub and sensors. It makes setup really easy. The sensors track temperature and humidity. The latter isn’t exactly important to me, but there are a lot of cases where you’d like to track how humid an area is so I like it’s an option. The hub syncs up via your home’s WiFi to an app on any smartphone. For me this is the bread and butter of this system. It allows me to set alerts on my phone for when the sensor is outside of the temperature range that I chose. You can also choose to be emailed alerts. We’ve already had the door left open by a guest and thanks to the alert I was able to close it before any spoilage occurred. So they’ve paid for themselves. The sensors use just one AAA battery. That makes powering them super easy as well. *What I didnt like*: Nothing, really. *The Bottom Line:* This is a fantastic system for tracking temperature. The sensors have a crazy long range (even considering that they’re inside of a fridge that almost certainly reduces signal). The temperature readings are accurate. And best of all, they connect to an app that lets me build custom alerts. Five stars out five. I love these and would definitely buy them again.

I have 4 of these devices in my house. I’ve had a few issues setting these up. Customer Service has been exceptional in guiding me through the process of completing the setup. I highly recommend this product and company.

I bought these to monitor the temperature in my pump house and in the freezer in my office. This device works perfectly, and exactly as I hoped it would. I had to call customer service for some assistance in setting it up, and they were very helpful.
