WiFi Freezer Thermometer Alarm with Digital Monitor Hub, App and Email Alerts, 2-Year Data Export, No Subscription Fee, 2 Remote Temperature Sensors for Home Refrigerator, Fridge, Freezer

I don’t usually write reviews, but this one earned it. Setup (5–10 minutes, no friction): Plug in the hub, download the app, connect to WiFi, and pair the sensors. Everything worked on the first try—no troubleshooting, no confusing steps. The app walks you through the process clearly, which I really appreciated. Performance & Reliability: I’ve been using this to monitor both my fridge and freezer, and the readings have been stable and consistent. Updates come in quickly enough to feel “real-time” for practical purposes, and I haven’t seen any dropouts between the sensors and the hub. Alerts = Peace of Mind: This is the real value. You can set custom high/low thresholds, and notifications come through immediately. I actually caught a temperature spike early, which likely saved me from losing a full freezer of food. That alone paid for the device. Build Quality: Sensors feel solid, not cheap or flimsy. Everything looks and functions like a well-thought-out product rather than a rushed gadget. Who this is for: Anyone with a garage fridge/freezer Meal preppers / bulk shoppers People who travel and want remote monitoring Anyone who just wants to avoid spoiled food surprises Bottom line: Simple to set up, reliable in daily use, and the alerting actually works when it matters. It’s one of those devices you don’t think about—until it quietly saves you money. Highly recommend.

I don’t write reviews very often. I have found the remote temperature products sold by MOCREO to be outstanding! On April 1, 2025 I bought the LCD Display Hub called an H5-Lite and two ST5 Temperature Sensors with external temperature probes. The ST5 only measures temperature. I was concerned that the Bluetooth communications would not reach one of the sensors placed a 100 feet away through an outside house wall and vegetation to monitor pool water temperature…range was not a problem. The second sensor was placed to monitor a refrigerator in the garage several internal house walls away. Range again was not a problem. I made sure not to put the sensor module in a location that was surrounded by metal that would attenuate the Bluetooth signal to the H5-Lite. All sensors come with a Velcro attachment and it works to place the sensors and probes. The smart app was easy to use and it easily was configured to my home WiFi. I followed the initial order by buying a temperature probe for the H5-Lite and ST6 which measures humidity and temperature. I followed that order with an additional order for a ST5 and ST6. All sensors measure temperature within a tenth of a degree with each other and are accurate with other high accuracy temperature sensors I have. The humidity sensors also are very accurate. The batteries have been exposed to temperatures up to 115 degrees Fahrenheit over the summer and have not required a recharge in 6 months. Battery life is excellent. The H5-Lite software has been automatically updated and is reliable. I’ve had no problem accessing the data via the Internet. The pricing for the MOCREO is very reasonable for what it does. The only problem I encountered was when I put the ST5 sensor in an outside plastic waterproof box. With the heat of the summer, the enclosure eventually crushed the temperature probe cable. I contacted MOCREO and told them what I had done. I fully expected to pay for a new probe. They sent me a replacement cable free of charge and I modified the outside box not to crush the cable. They provided excellent customer support and if I can think of other applications, I’ll be ordering a MOCREO!

Very easy to set up, great features, and works flawlessly!!! I really like the notifications sent to me if the temperature drops. With our other alarms you had to be in the garage to know it was going off

This is a great product. Does a very good job, easy to set up and simple to set. Only issue I have is the temp fluctuates too quickly. It would be better if the probe wires were longer to get away from the door.

Excellent temp sensor for my freezers. Easy setup and works great

A couple of years ago, the freezer in the garage was left open after kids got into it. about 100 pounds of meat spoiled. A few months ago the same thing happened - this time when the door was left slightly open. Another 50-ish pounds lost. That's not happening again. Installation is easy. The sensor has a built in battery - just pull a tab. There's a little mount with double sided sticky tape for the temp probe, so mounting it is straightforward, too. You don't need to install an app, but you probably should so an alarm will go off on your phone if the temp gets outside of what you say is OK while you are away from home. The display, which is bright, easy to use beeps when alarming, and is loud enough that most of the first floor hears it but for some reason nobody upstairs could. I don't know exactly how long it was from the time I warmed up the sensor until the alarm started beeping, but I'd guess it was around 5 minutes. The probe has a thin wire that you shut the door on and connects to the sensor. The sensor and the display connect to wifi and can connect to the internet for you to get information on your phone like alerts and even a graph of how temperatures have changed. I know this thing says that it's good for a huge range of temperatures, but all I've used it for so far is in the freezer which runs about 7 degrees F. It does come with 2 probes/sensors. Maybe I'll put the other in the kitchen fridge.

The MOCREO WiFi freezer thermometer alarm is a good solution for monitoring your walk in coolers and freezers. We do food service for 15 apartments and always have a large amount of food in our freezer and cooler. This item is affordable and meets our basic need to watch the temperatures in our refrigeration.

The LED screen with two sensors works great! We have a freezer and refrigerator in it garage. Occasionally, the door doesn’t completely shut and it gets warm. Since we rarely go in the garage, these sensors track it for us. The LED screen starts blinking red if the temperature is it if range, and sends emails too. You can also set a delay for how long a sensor can be out of range before sending notifications. This is good because we have the sensors close to the front, and they warm up when the door is briefly opened. The whole system works great.

I bought this item in August 2025 after having lost everything in my freezer 3 times in the last 2 years. The first time, someone put the groceries away poorly, and the door didn't close all the way. Boom... there goes $500. Then (probably because of the first incident), the compressor went, and I lost everything again. So, I bought a new freezer... and 3 months later the freezies are melting (I'm still not sure why on this one). Enter the MOCREO WiFi Thermometer Alarm with Digital Monitor Hub. This thing is amazing, because it just WORKS. Put the batteries in the remotes, put the sensor in the freezer and the remote on the side or top, download the app, and connect. Set alarm temperatures in the app (one for each remote), and walk away. Or drive away. You'll get an alert on your phone whenever the temperature goes above the alarm value. And the hub will beep at you in a very annoying manner (so your kids can't just ignore it!). I also love the little graph of freezer temperatures. I can even see when my freezer goes into Defrost mode, as the temperature rises from -19 degC to -10 degC before going back down. So, massive kudos to MOCREO for being the ONLY device that advertised exactly what I wanted: an internal freezer temperature monitor, with external battery (so battery life is super long; mine are still showing as full), connected to a central hub and to an app on my phone, and DELIVERED on every aspect. Even the firmware updates on the Hub are super easy. Give the team that designed this system a bonus!

Esta alarma de termómetro me ha sido muy útil para monitorear refrigeradores y congeladores. Fácil de instalar y usar. Lo recomiendo ampliamente.

I purchased this freezer alarm after loosing $$$ of food. (Door open). Easy installation and works great, I tested the alarm and notification. Both came through right on que, it was set for a 10 minute delay. Would definitely recommend this product.

This little gadget works great...Connection is quick...can check on my freezers from anywhere. If the hub is within 25 ft or so... it connects to the sensors instantly ..I actually bought a second one so I now have two hubs...one I pass by on my way to sleep and a second at my main home exit. The screen is really bright and easy to read.

Excellent product. Very happy with it and so are my clients. Easy installation. Installed in 8 commercial freezers and fridges for temperature monitoring.
