MOCREO 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 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!

Works great! Easy setup. Very accurate on both sensors. I thought my deep freezer in the basement had gone bad and would need to be replaced. I decided to try this in case it wasn’t the compressor. It clearly showed that the freezer would get cold enough, but then would not cycle back on until it got much too hot. So I ordered a $13 thermostat off of Amazon and replace that. Problem solved and freezer works as good as new. And the best part is if this ever happens again, I won’t have to throw away all that food. I will get an alarm on my phone and have time to do something about it instead of finding out too late.

This thing is the best. I use it to make sure my deep freezer full of hard-earned breastmilk on my balcony does not thaw- it protects my stash in the event my freezer fails or it gets left open a crack or whatever. I keep the display in the central part of my house. I programmed it to alarm if the freezer goes out of range, which it has briefly a few times, but luckily the app lets you pause the alarm. I love that I can look back on the graph and see what the temperature in the freezer actually runs. It protects my liquid gold so well! I had another wireless app-based monitor but it was huge, the battery only lasted a few days, and it kept disconnecting. The MOCREO has worked flawlessly with no charging or batteries required. The only minor annoyance is the wire that somewhat messes with the freezers seal, but any device with this design will have that issue. Totally worth it. I use the second monitor to make sure my baby’s nursery is an acceptable temperature for safe sleep. 9/10 would absolutely buy again. Gives me peace of mind and an ability to intervene should the freezer temp dip before my entire stash (hundreds of hours of labor and love) is ruined.

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.

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.

This product works. Bought a 2 pack unit to monitor my freezers while out of town. Not only could the person house sitting see the freezers were ok, so could I from the remote monitoring app. With the cost of meat today knowing my freezers were working was a significant piece of mind. Frequent power outages are a thing here but knowing the temperature was within limits and being able to graph the changes and fluctuations is well worth it. Had an issue ( my fault) with a sensor before I left and had a replacement delivered several days before my trip. Fast and curtious serve. Can’t be beat! Just buy it. You will be glad you did.

Excellent. Easy to install. Small & compact. Easy to understand instructions. Hooked up to our Internet immediately. We have a large investment in several freezers, now we can check out the temps while out of town. Great feeling to know everything is okay. This reduces stress Incase of power outage or flipped breaker. Just ordered 2 more for the other fridge/freezer units in outside storage building. Small price for piece of mind!

easy to set up and extremely useful. Better quality than I expected

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

This product works very well. I’m glad I bought it! I’d buy it again in a heartbeat

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.

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

Facile à configurer et installer dans le congélateur donne la température à distance avec des alerte sur l’application et par email . Léger givre a causé du fil après une semaine d’utilisation
