    I had a need to monitor 2 refrigerators and 1 new upright freezer. These fit the bill perfectly and at a great price as I purchased 3 of them. My first foray into LoRa technology, Im happy I chose these as I can view temp/humidity levels in all 3 units on my phone, and get alerts if they are out of a range I set for each device. As far as accuracy, I cannot report as I do not have a NIST-traceable standard in which to compare. As far as precision, the fact they are in close agreement speaks to that (see photo). Primary down side to these devices is that you need another app on your smart phone to view. Bottom line: Very good value and I would/will continue to buy as the need arises. Update: May, 2023 After a year using 3 of these, I can say with complete confidence that they are BULLETPROOF. They have been reliably monitoring 3 appliances with perfect continuity, reporting and alerting. I think the hub and LoRa technology makes all the difference as the handful of cheap WiFi smart thermometers keep dropping off the network and overall, just frustrating to use. The YoLink devices never drop out and I have confidence that I can monitor my appliances (and soon a room) while Im traveling. Im buying another today and perhaps more later. You cannot go wrong with the YoLink system.

    I confused two products that I bought. Check my Govee review for this YoLink item. I blame Amazon for not having the product brand name on the items to review page … and the icon photos are extremely small! Amazon gets a 2 star on that “service”

    This worked great for 9 months. Stopped working. Contacted customer service (I use that term loosely) they gave me the run-around. Did nothing to solve my problem gthey finally sent, and this is true, a message that said, Have a great day. If you get a usnit that wokrs, youre good, but if you dont, sorry.

    Bought this to monitor the because it had a better range than other options. I needed to monitor the temperature/humidity in a coldfrrame in my garden. It’s down the hill from my house so I wasn’t sure if it would have the range I needed. Just pugged it in and set it in the cold frame. It works great! I think I will buy another for my small greenhouse in the same location!

    I have had several temperature sensors and leak sensors set up in each of three different homes. I have monitored up to 32 sensors at one time. I have leak sensors at all of my plumbing fixtures. I placed temperature sensors in a couple of locations in the house, in my fridge, and in my freezer. This is the best system I have found. It’s easy to update when moving to a new home. I can check status at a glance and can sit notifications on temperature and humidity parameters. I change the batteries about once a year.

    Wow that was Easy press that button on the back to turn on sensor and setup in app. Of course setup the Hub first. Create and account after connecting Hub.. I connected my hub directly with network cable. Hub does support wifi connection to your network. Once Hub is powered up in app just click the Add icon upper right, enable app to use camera and scan QR. Next click the Add icon again to add your sensor scan QR on sensor and well did I say it was easy. Next go to your Alexa app and go to Skills and add Yolink and Enable and link your account. No need to scan for new devices in Alexa. Just say Alexa what is the temperature on the Themperarure and Humidity sensor you can change the name of the device but ha that was so easy. Did I say it was easy...

    I ordered the hub with 2 temperature sensors and ordered a third temperature monitor as we have 3 freezers wed like to manage. It took me a little bit to figure out how to set the settings to trigger an alert to my phone when the freezers hit a warmer temp but once I figured it out it was smooth sailing! We have 3 deep freezers and would be a bit devastated to not know a freezer failed before it was too late Our freezers are in a detached garage but we do have an ethernet cable in their so have the hub plugged in out there. So far these have been working great!!

    I put one of these in each of my freezers. Even the one out in the garage gets a good signal! It is peace of mind to know I will be notified if there is an issue with the temperature before it is too late.

    Although YoLink does not support the major home automation protocols like Z-Wave, Zigbee, Matter or Thread, these devices have a major plus, they work, they work the first time and very easy to set up which cannot be said for the above protocols. Adjustment provided if you need to make an adjustment to temperature readings, mine were close enough that I did not bother. History display is excellent and alarms seem to work as intended. Note that it requires its own hub but the hub is inexpensive and only one is needed. I have not tried to get system to work with Google so can not speak to that. Excellent for use in freezers, work well through the steel box.
