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

We travel during the winter and want to insure our home is above freezing. So far the sensors and program are working well

I use these for the deep freeze I put my breast milk in. It helps me keep track of the temp and notifies me when it gets too high.it does connect to Wi-Fi so if we lose power it wouldn’t work but luckily I have a backup plan. I recommend these they have been great for me so far for peace of mind.

I can leave my house and know in an instant whether or not my heating system is working properly after having had problems in the past. Great product. Excellent price.

Los estoy utilizando en mi heladería y tengo que decir que funcionan muy bien. Los sensores de movimiento, los 3 termómetros, los sensores de puertas el hub y el altavoz. Todo está trabajando muy bien. La aplicación es un poco complicada de configurar si necesitas que funcione específicamente en ciertos horarios y que tengan un alarma específico. Pero se puede lograr. El hub lo tengo conectado con cable ethernet y los varios sensores están en un local de 110 metros cuadrados con varias paredes. Recomendados.

We have a refrigerator out in our uninsulated garage. I wanted to monitor the temperature for 2 reasons. ONE, during the winter I want to ensure temperatures are maintained. TWO, this is an old fridge, so I want to be alerted if it stops working altogether. I love that these monitors collect a history so that I can easily keep an eye on things. I found the setup to be very easy and quick. I connected directly to wifi using my Eero system. I love that there will be alerts sent directly to my phone so that I can take action ASAP. I just installed this today and I will absolutely update my review if anything changes.

Excellent product. Excellent range. I have both motion sensors and temperature sensors and they work great! When I upgraded my Internet service provider, I had to make sure all of my devices were working and had trouble getting this to connect to the new service. After spending about two hours trying to reestablish communication between the hub and my Internet, I finally called customer service. But helpful person got to the bottom of the problem almost immediately. (I had the device plugged into the modem instead of the router!!!!) So… The only problem I’ve had with the products have been my own fault. I monitor motion in my garage and car that is parked on the street and temperature at my cabin while I am at home in a different city. Great peace of mind and fantastic products!

These sensors work amazingly well even inside your freezer. The supplied hub plugs into your router and receives a solid signal from each of the included sensors. Our freezers are in the garage. I have them packed with wild game and other expensive meats. Loss would be catastrophic. These sensors send a solid signal and alert me on my phone when the temps enter dangerous ranges. So far they have worked flawlessly. Cheap insurance.

I ordered the hub with 2 temperature sensors and ordered a third temperature monitor as we have 3 freezers wed like to manage. It took me a little bit to figure out how to set the settings to trigger an alert to my phone when the freezers hit a warmer temp but once I figured it out it was smooth sailing! We have 3 deep freezers and would be a bit devastated to not know a freezer failed before it was too late Our freezers are in a detached garage but we do have an ethernet cable in their so have the hub plugged in out there. So far these have been working great!!

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!

We purchased this to alert us to power loss or freezer failure. Our two sensors are located one in each of our freezers. The hub hooked up via ethernet. Easy to scan hub and both sensors into the app on phones and set up alerts. The few questions I had were answered quickly by customer support via email so we have been happy with this purchase and it is doing what we need it to. We had a power outage and received notification on our app and via SMS so we could monitor and respond.
