About This

• 24/7 Remote Fridge & Freezer Monitoring: Check real-time temperatures anytime, anywhere through the MOCREO Smart App with this WiFi freezer thermometer — whether you're at home, at work, or away on vacation. Perfect for monitoring your fridge, freezer, or garage fridge without ever being home.
• App, Email & Local Buzzer Alerts — Three Ways to Never Miss an Alert: Three independent channels notify you at once: an App push notification, an email, and a loud 90dB Hub alarm, so at least one alert will always reach you when your fridge or freezer needs attention. A reliable freezer temperature monitor built for everyday peace of mind.
• 168-Hour Outage Data Recall — See What Happened While Power or WiFi Was Down: When power or WiFi goes out, MS3 keeps recording up to 168 hours of temperature history locally, so you can review the missing hours after everything comes back online. Instead of guessing whether your fridge or freezer stayed cold enough, open the app, check the outage period, and decide with confidence whether to keep or toss your food.
• Power Outage Alert Within 25 Minutes: When a power outage is detected, the MOCREO system sends an app and email notification within 25 minutes — and alerts you again when power comes back on — so you always know what happened and can quickly decide whether your meat, food, or milk is still safe.
• 0.9mm Ultra-Flat Probe — Designed for Cold Storage: The 0.9mm ultra-flat cable slides easily through your fridge or freezer door seal, helping prevent cold air leakage and frost buildup. Industrial-grade accuracy (±0.9°F) over a wide range of -40°F to 158°F ensures reliable long-term monitoring — making this wireless refrigerator thermometer easy to set up and trust.
• SMART Alert System — Built for Real Fridge & Freezer Monitoring: Set a delay time (e.g., 5 minutes) to filter out false alarms from door openings or defrost cycles. iOS Critical Alerts notify you even in Silent or Do Not Disturb mode, while Remote Mute lets you silence the Hub buzzer from the App without running to the freezer. Low Battery alerts keep your monitoring running without interruption — everything you'd expect from a capable freezer alarm kit.
• 2-Year Battery, 2-Year Free Cloud History & Alexa Compatible: Runs up to 2 years on 3 AAA batteries, with Low Battery alerts sent in advance so monitoring is not interrupted. Under normal connected use, temperature history is stored and exportable for free for up to 2 years. Alexa support lets you check the current temperature hands-free, and one Hub can manage up to 30 sensors for expanded home monitoring.
