YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range (-22 to 158 Degree) for Freezer, Fridge, Green House, Pet Cage, Smartphone Alerts - Hub Required

I started out using YoLink water sensors September 2020 (4 sensors w/ hub). Installed them in my finished basement and laundry and didnt really give them much thought until I received my first notification/alert, I was doubtful but immediately went to check and low and behold, I had a slow leak in a slop sink. These sensors saved me from a HUGE headache. I went and bought another 4 pack and have these sensors EVERYWHERE. Now that I have the water issues under control, I have started to work on humidity & temperature in my home with their sensors. Temp & humidity sensors are just as easy and accurate! These are great products and I look forward to what new products will be released next.

The device seems to work well in its app and is pretty accurate compared to other thermometers. I am having problems with Alexa integration and plan to call tech support later today. It shows up on the Alexa app and Alexa can tell me the temp if I ask. The problem Im having is that its not showing up under Smart home in the Alexa app so I cant setup a routine.

Perfect so far. Already has save a freezer with 1/2 a side of beef. Door was left slightly open. Alerts on my phone went off late in the night. Saved!

I already have a hub and 3 sensors. Adding 2 more was as easy as scanning the QR and pressing the button. I added one to my shop and the other to my greenhouse. Setting the temperature alarms was just as easy! I tried other temperature sensors and they just didnt have the transmission range. Battery life is fantastic! If you need to monitor temperatures, Yolink is the way to go!

Used for bearded dragon tank

Nice to be able to check it and get alerts in case power goes out so we don’t lose our frozen meat investment.

Easy to instal - includes downloadable manuals and videos.

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.

Love having an App on my phone to check my stand up freezer temperature wherever I am at. Took a bit over 10 minutes to set up. Well worth the sense of security knowing that my food is safe

I have two of these sensors, purchased mostly to monitor the fridge sensor. The first one had a faulty antenna, it fell out, so the range is quite poor. The other goes through batteries very quickly, its faulty in some way. Other than those two flaws they seem to work quite well.
