24/7 Remote Freezer & Fridge 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.
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 80dB Hub alarm, so at least one alert will always reach you when your fridge or freezer needs attention. Designed as a reliable freezer temperature monitor for everyday peace of mind.
Power Outage Alert — Know the Moment Power Goes Out: When a power outage occurs, the MOCREO system instantly sends an App notification and email alert with the exact time power went out and came back on, so you can decide right away whether your food is still safe to keep.
Pass-Through Outlet Hub & Up to 30 Sensors Management : Unlike most monitoring hubs that block your wall outlet completely, the H3 Hub features a built-in pass-through outlet so you can still plug in other appliances after installation. Its compact design also avoids blocking neighboring outlets — ideal for kitchens, garages, and basements. One Hub can manage up to 30 sensors.
0.9mm Ultra-Thin 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 temperature range of -40°F to 221°F ensures reliable, long-term cold storage 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 ensure you’re notified 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 also keep your monitoring running without interruption — everything you’d expect from a capable freezer alarm kit.
2-Year Battery, 2-Year Free Data Storage & Alexa Compatible: Runs up to 2 years on 3 AAA batteries, with Low Battery alerts sent in advance so monitoring is never interrupted. Temperature history is stored and exportable for free for up to 2 years, and Alexa support lets you check the current temperature with just your voice — a wifi fridge thermometer built for long-term, hands-free monitoring.
