Smart Wireless Temperature / Humidity Sensor Wide Range (-22 to 158 degrees) for Freezer Fridge Monitoring Pet Cage/Tank Monitoring Smartphone Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included

I bought these to monitor the temperature in my pump house and in the freezer in my office. This device works perfectly, and exactly as I hoped it would. I had to call customer service for some assistance in setting it up, and they were very helpful.

Out of the box this had batteries installed on the remote sensors which was nice. I plugged in the hub via ethernet into the home router. I have one unit in a fridge and there are no signal issues reaching the sensor as well as the freezer in the garage. Range appears good....signal strength in fridge which is upstairs is still -77dBm). The signal strength for the other sensor directly upstairs from router is -52 dBm). No issues or concerns having these dispursed either in something or further away from the house router. Functionality is also easy to set up alerts or see charts with the data. knocked one star off for lack of ability to enable a push for an updated temp from the sensor. The booklet has the requirements for for a refresh based on one of 6 conditions...otherwise its 1 time per hour. I would prefer a SW update that enables a manual refresh.

Using LoRa (long range wifi) this works very well. I have one sensor in my fridge and the signal easily gets through the fridge walls and to the hub 3 rooms away. The alerts are sent to email and/or phone by way of the hub. Set up was easy. The app assigns a widget to each sensor but oddly doesnt label each widget with the name that you assign to each sensor in the set up routine. But thats minor and you can see which sensor name is assigned by choosing a label in the app. Very cool. Now I can see when the fridge door is kept open too long by the wife, ha ha!

My fridge/freezer starting showing signs of failure so I bought this Yolink device to monitor them and get notified of issues. IT JUST WORKS! Simple to configure, works reliably, and does exactly what it’s designed to do. I especially like the flexibility in alarm settings and also alert settings. I would absolutely recommend this product to anyone. It’s worth every penny!

Good Quality, and accurate

Bought to monitor the temperature of our pump house. A small cinder block building separate from the house. The sensor has no trouble staying connected to the hub inside the house. Battery lasts a little over a year, even in the remote building through multiple walls. I am very impressed.
