Super easy setup, great app, really does work from inside a metal fridge. Alerts work well.
By JP on Reviewed in the United States on December 29, 2024
Setup: Setup could not be easier. 1. Install app, 2. setup hub 3. add sensor(s). 4. Update Firmware. To make the hub setup quick and easy it's best to connect the hub to your router with an ethernet cable. The instructions have you scan a barcode on the hub using the app to register it, then power it up. It came online within a few seconds. WiFi can then be setup while it is connected via ethernet cable. If you wish to use WiFi power off and relocate the hub. It takes about 30 seconds to join WiFi after being powered up. Adding the sensor(s) is similar. Scan the barcode on the device with the app, then turn it on using a switch on the back of the unit. It will connect to the hub quickly. It is best to configure all the alerts and other settings while you have the sensor on a desk, then when the configuration is complete place the sensor where it is needed. Both the hub and sensor had the latest firmware as delivered which is awesome. Use: The LCD's still work even at freezer temperatures of -5f. The batteries in the LCD sensors will not last very long in a freezer. maybe 9 months, I have ordered some sensors that do not have an LCD and come with Lithium batteries good for 5 years. I'm really impressed how well the sensors work inside a freezer clear the other side of the house from the hub. It lives up to the hype. Sensors contact the hub about once per minute. App: The app is very good, there are some really detailed statistics you can view and there is an option to download data. I have included a screen shot of one of the charts showing a 24 hour view, Alerts: After setting thresholds, alerts can be sent via the app on your phone, an email, or SMS. SMS is limited to 15 SMS's per month but email works just fine and has no limit. Yolink Eco system: The number and variety of devices you can add to the hub is impressive. Given how easily the system and app works I'll be adding devices in the future. Highly recommended.

SMART HOME STRETCH: PARTIAL CONNECTION CONFUSION 🌡️📱🤔 [⭐⭐⭐☠️☠️]
By Jay Fray on Reviewed in the United States on April 14, 2025
Jay Fray delivering the nuanced truth about this YoLink temperature sensor that promises more than it delivers on the integration front. 🧐 Picked this up primarily for its advertised Amazon compatibility, expecting seamless integration with my existing smart home ecosystem. The device itself isn't terrible—setup was relatively straightforward through the YoLink app, and the sensor provides consistent temperature and humidity readings that appear accurate when compared to other gauges. 🌡️✅ The physical construction is decent enough—compact design that blends unobtrusively into most spaces, with a clean display that's easily readable from a reasonable distance. Battery life seems solid so far, with no significant drain after several weeks of continuous use. 🔋👍 Where this product seriously underwhelms is the misleading "Amazon compatible" claim plastered all over the listing. Yes, it technically connects to Alexa, but the implementation is so limited it's practically useless. You can ask for the current temperature reading... and that's basically it. No meaningful automation, no conditional triggers based on readings, no integration with routines—none of the functionality that makes smart home devices actually "smart." 🤖👎 The YoLink app itself is functional but uninspiring, with a dated interface and occasionally laggy performance. Historical data tracking works but lacks the analytical tools or visual representations that would make the information truly useful. 📊😐 Jay Fray verdict: A serviceable temperature sensor that falls short on its primary selling point of smart home integration. If you're simply looking for remote temperature monitoring through a dedicated app, this works adequately. If you're expecting meaningful Amazon/Alexa integration to create a cohesive smart home experience, prepare for disappointment. Sometimes average is just average. 🏠🤷‍♂️​​​​​​​​​​​​​​​​
