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

This could not have been any easier to set up. Took ten minutes from opening box to sensor in freezer sending readings. Signal from freezer sensor in garage to hub in living room is full strength. Highly recommend

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.

I must be honest and say I was a bit skeptical about this product at first (placing a wifi device inside a sealed metal box), but let me tell you, it really works! Once you get the thresholds set it will send you a notification directly to your phone (via email) when the temperature or humidity has exceeded your setting. Be mindful of your defrost cycle. It will send false readings if you have your threshold set to low. Once I got that figured out, it has worked flawlessly. You can monitor it in real-time via a graph in the app. Super impressed with this little device. It definitely gives peace of mind that my freezer packed with venison will be safe and sound on my next hunting trip.

After 6 weeks of use in our RV basement we are very pleased with the performance. We want to monitor the temp and humidity down there due to being in freezing temps. Love the phone app with the ability to set alarms.

We are currently using in a k-12 school system to monitor all our coolers and Freezers. Easy installment. App is easy to use. 24 hour monitoring with text, app alerts and email alerts. Economical! Highly recommend! Have not needed text support yet.

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 use these in my garage fridge/freezer. We have a stand-alone garage, in SoCal. So it gets HOT in the summer. It is also on a separate circuit from our home, so if/when the circuit randomly blows, we have no way of knowing unless we go in the garage and try to turn on the lights. That makes this thing super useful. Of course, when we go out of town, now well also know if theres a broader power outage and our food is all gone bad. It was a cinch to set up, and the app is very functional. I love that I can set a temperature range. It helped me a) make sure we had the fridge and freezer set to good settings for the temperature we wanted and b) establishes an alarm so we know if something has gone wrong and the power is out in the garage.

Purchased this for our garage refrigerator / freezer after reading some horror stories about food spoiling because of not knowing the refrigerator or freezer stopped working. This took only a few minutes to set up and install. Integrated with the phone app after only a couple of tries. Adding the Alexa skill was easy as well. Now if there are any temperature excursions I get push notifications on the app and an email. I can also ask Alexa what the temperature is at any given time. Also, the 2 sensors (1 in the fridge and 1 in the freezer) have great wireless communication with the base unit which is inside the home in another room. Would recommend.

Moving into a new house and want it setup the way you want and with affordable and reliable products. This is the best way to go as far as I know. Many optional monitors and devices available and does not require allot of hubs. Very easy to add devices as you progress

I had two devices side by side and they showed two different temperatures. Now I have one in a freezer that alarms raising the temperature to 5-10 degrees, the freezer has a digital thermometer display and it doesnt reflect an increase in temperature.
