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.

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!

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

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.
