These little monitors are amazing!
I bought these for my home and vacation home. I have them plugged into a timer of just a few minutes a week and the battery has stayed at 100%. So far they have lasted over 1 year (with no maintenance) and I HAVE PEACE OF MIND knowing that my refrigerators and freezers have not failed. Serious damage could happen while I'm away and these things work wonderfully!! Who knew?? They let you know when the temp is too high and when it lowers back to a normal range. Easy to set up with the app, monitor and forget worrying that your home is being destroyed with water damage!

Great addition for aquariums. Would recommend to any fish keeper.
I am an avid fish keeper and I breed L400 plecos. I purchased the MOCREO system to monitor our 4 aquariums. I purchased 4 units plus the LCD screen three months ago.The SensorsI find the sensors to be pretty accurate. I checked them against a certified food grade thermometer. The app allows you to offset the temperature and adjust this for accuracy. I adjusted one of them by 1 degree.I had one DOA sensor (it was actually the thermometer cable, not the sensor itself) and they replaced it next day. The thermometer cable plugs into the sensor and can be replaced. Otherwise, they were pretty easy to set up. Within the app you add a new sensor, and then hold down a button on the unit. Similar for the LCD display.The sensor units come with velcro and sticky backs so they were easy to hide somewhere behind the tank or inside the cabinet. I have had no issues with range despite hiding them within the cabinet and having some tanks in the basement. I haven't had to change a battery yet either.The DisplayI love the LCD display. I like talking about it and showing people as well. I'm a dork like that. The alarm is loud and very effective. So effective that if I am changing fish tanks, I'll just unplug it until I'm done. It connects to the wifi just like the sensors so it doesn't rely on your phone to work.The AppThe app is easy to use and integrates well with both the sensors and the LCD unit. It has live monitoring and history for each sensor. You can check temps and adjust settings from anywhere on your phone. You can receive push notifications and email alerts as well. Managing sensors is pretty easy. You can set up different rooms in the app but I didn't see a need to go through all of that. The service is free and I didn't have to pay anything.Real use scenarioThe weather turned cold this weekend, and the basement is about 65 to 68F. The 300w heater I had was struggling to keep up so I received alarms from the app and LCD display. I added a more robust heater and I can see in the app that it brought the tank up to temperature over 12 hours. It also shows that I need to adjust the heater by 1 degree. An event like this is exactly why I purchased this system. It also reminded me that I never left a review.ClosingI really have nothing negative to say about this system. It has added great value to my aquariums. I would recommend it to any hobbyist. I fully intend to buy another sensor for the deep freezer in our garage too. U just keep forgetting.I added a picture of pleco babies for your viewing enjoyment.

One of the best values of recent purchases.
I have implemented the two sensors with one in the greenhouse and another on the back porch. Love it! Alerting and reporting can be setup to be sent to phone with daily temperatures hourly reporting in CSV format sent to email. The hub displays current sensor temps and can show graphics of temperature ranges per sensor. Hub display is small, brilliant, and easy to setup and view. The hub has become our official clock and temp source for viewing before going outside. This product has provided one of the greatest values in recent purchases.

Excellent system. Highly reliable even outdoors exposed to heat and salt air. Easy to setup. This is my second hub.

Works great!
We keep a spare side by side refrigerator/freezer and an upright freezer in the garage. When my daughters family moved in with us we needed a little more space for drinks, left overs, etc. I picked up a used refrigerator ( freezer on top) from Facebook marketplace. In the first month I found the breaker tripped but everything was still frozen. That got me thinking with so many people in the household there’s a greater chance of someone leaving the door open. So I searched and found this Mocreo device. The setup was easy and it works great. It helped me diagnose a defrost problem with the new refrigerator. I love that I can get alerts when the temperature is out of range or when the power goes out.

Great inexpensive peace of mind for your fridge and freezer foods!
Put one in my new garage ready fridge and put one in my deep freeze. They works great! Good instructions made it easy for me to set up. Really nice to pull up the temps on their app and see temps in real time and review the min/max history chart. Big piece of mind knowing I'll receive alerts by text and email if the temps I set in the app go above or below the set points I chose. The wifi hub also gives an audible alarm if set points go out of range or power goes out. Love these!

Product Works!
We just set this up on Saturday, 2 days ago. This morning the alarm went off to let us know that one of our freezers temperature was over the range of degree we set up. This freezer stopped working 2 weeks ago and we caught it before our food thawed out. My spouse replaced a part, and it started working again, but we didn't know if this was the problem.
