ST10 Ultra Low Wireless Freezer Thermometer, -328°F to 392°F Temperature Alarm, Email & App Alert, Data Logging, No Subscription, for Lab Medical Vaccine Refrigerator (Hub Required)

**Title: Exceptional Wireless Thermometer and Freezer Alarm - A Must-Have!**I purchased the Marco MOCREO ST5 wireless thermometer and freezer alarm Hub in July 2024, along with its required hub, and I couldn't be happier with my decision! Setting it up was a breeze, and it seamlessly connected to our Wi-Fi, reaching an impressive distance of over 130 feet. In fact, we even tested one of the sensors in our car while parked, and it maintained a solid connection from the parking lot!As a pantry dedicated to helping feed the poor, ensuring the safety of our food is a top priority. These thermometers have been instrumental in keeping our supplies safe for our clients. I highly recommend them! The product is not only reliable but also user-friendly.We did encounter a minor issue where one of the sensors got unplugged, but the alarm system quickly alerted us with additional icons, allowing us to address the problem immediately. The ability to set temperature ranges and receive notifications if one of our freezers fails provides us with invaluable peace of mind.Customer support was quick and excellent, addressing our questions efficiently. The app is fantastic, giving us real-time access to the exact temperature of our freezers right on our phones. Overall, you can't go wrong with the Marco MOCREO ST5 and HUB. It's an outstanding product that offers peace of mind, making it essential for anyone needing to monitor temperature-sensitive items. Five stars all the way!

Works great for monitoring my freezers and keeping pace of mind that our food supply stays safe.

i purchased the hub and 2 sensors a while back and since added 2 more sensors. App is great! It logs all. It will TXT you if a freezer temp is out of programmed parameters!!!!! Excellent!!! I could not be more pleased with this company and system.

Great product. I no longer worry about a problem with a freezer or refrigerator failure without a warning that I have a problem. It has an audible alarm and it also sends me an email if the temperature goes above or below my preset temp range. I first bought the package set and then bought extra sending units for my other refrigerators and wine fridges.

Easy set up and tech support at the company went above and beyond expectations. Pleasure to get this product!

We have them on every deepfreeze in our basement. It's awesome to glance on the counter at the information center and see what everything is doing. Also has an alarm feature....

My Govee and Acurite sensors either fail to work or barely work through the thickness of a freezer or refrigerator. Mocreo separates the sensor from the transmitter/receiver, so you get a better signal.I don't love the requirement of a hub (none required for Govee), but at least Mocreo identifies their devices (MAC or S/N) so you know which sensor you're placing and which it is on your mobile app.The mobile app is OK.I had trouble keeping the hub connected, so i think it's an issue with the 2.4ghz WiFi line of sight - you aren't relieved of that hassle here.Still, a small improvement over the other IoT temp/humidity devices I have tried with > 4 sensors.

Have had this system (with the hub) in place for easily 2 years now, possibly 3? Been flawless (although - it would be nice to see a glass bead/glycol based probe that more accurately reflects temps versus the air temp based probe)Recently had an issue where a sensor went offline and found the battery to have bulged for some reason, splitting the case - Reached out to customer support on July4th and got a prompt response on the 5th by Stephanie, who was AMAZING. Today found out they are shipping a replacement at no cost.This is the customer service that keeps people and makes them want to chat up the product - (for which I've already been gabbing with coworkers about who need temp monitoring for their freezers).Amazing work Mocreo - Even MORE amazing customer service that is prompt, professional and courteous! Now if you come out with a glass bead or glycol based one, that would be AMAZING (Those would prevent alarms from going off with a rush of hot air coming inside, it'd take longer for it to raise the temp, which is what is used in vaccine storage systems)
