Great for Power Outages

We bought this to track temperature when the power is out. We had an 8 hour power outage recently while we were out of town. Even though our WiFi was also out it was storing temperatures. I was able to see the history once power was restored and knew we hadn't lost anything in the freezer and probably just some of the dairy in the fridge. It was very helpful determining what needed to be thrown away. It also gave me peace of mind to be able to see the data on the app when it would be several more days before we were home.

Yolink sensors are the best. I use them to keep track of everything from inside and outside temps to reptile enclosures and hotspots, even my koi pond temps. Pair them with some yolink plugs to automate everything. Then add some door sensors to know everything is locked up.

as described

fairly easy to set up. it appears to be accurate, and easy to monitor on my Android. The one issue is the hub is not super friendly to hook up wirelessly. I ended up plugging it directly into my router.
