WiFi Freezer Thermometer Alarm with Digital Monitor, App & Email Alerts, 2 Year Data Export, Remote Temperature Sensor for Refrigerator, Refrigerator,

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 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!

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