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 use several YoLink sensors to monitor for leaks and these for monitoring our refrigerators while we are traveling. I can check the condition of things around the house from anywhere on my phone. Gives me piece of mind along with my security cameras.

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.

Im usually skeptical with low cost devices, but I was in a situation to see if I needed to buy a new fridge, but wanted to know what was going on with it since it was starting to give me issues. So I purchased the temp/humidity sensor. Let me tell you, this system is awesome! The set-up was amazingly easy, and it was true to its word that it has a long distance connection. I have the fridge on opposite ends of my 2k sq ft home. It goes through walls and sends a signal to the (dedicated, sold separately wifi base) and provides me with notifications on my cell phone as I pre-set the qualifying conditions in which to notify me. Ive been talking to my friends about this unit. Highly recommend it.

Easy to instal - includes downloadable manuals and videos.

These temp/humidity sensors took the place of my old Acurite hydrometers/thermometers. They were more accurate and now I have alerting through Yolink. Absolutely no issues with connection or distance. Have one in my gun safe too and the signal is very strong.

I like this little home automation device. I works stand alone (you can easily read it). It has a nice app with possible automations and it integrates easily with other systems

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.

It seems like some of the complaints on these is that theyre not accurate so just to make sure I purchased several analog and digital temperature sensors to check them against their readings. I must say the temperature readings are spot on or at least within 1 degree of spot on which is pretty friggen accurate for such a small sensor. Overall these were probably the easiest things Ive setup in years and literally just scanned QR codes to get it to work; not a single problem the entire way! For something this affordable, adjustable, reliable, and accurate its one of the best investments Ive made in a long time! Hopefully this company does well because I cant wait to see what other sensors they can add to make my life easier! Ultimately you cant go wrong with these, there literally was zero downsides and I cant say enough good things about them!
