INKBIRD WiFi Hygrometer IBS-TH3-PLUS Temp Humidity Sensor with Display

I've only bought one and had it for only two months. So far, it works great. No issues with wifi reception. I have not checked RH and T accuracy, but if its off, its not by much. One comment for people who wish to calibrate these to a known accurate value - You'll want to calibrate temperature first and then RH.

This is by far the worst product I've ever bought on Amazon. I've had two of them. The good news is the setup is easy and only takes a few minutes. The rest isn't so good. The first one I had connected to my wifi exactly once and then never worked again. The second one worked for about a week. In that time, it connected every hour (as I set it up) for the first few days, then became sporadic. It also wasn't very accurate - sometimes it was only off by a couple of degrees, but one time it recorded a temp of over 2400 degrees F in my living room (I expected to come home and find my house in flames, but it wasn't), and another time it recorded a 20 degree shift in the middle of the night when my heat wasn't on. After a week or so, it refused to connect to the wifi, just like the previous one. I'm pretty tech savvy, and wasted waaaaaaay too much time trying to trouble shoot this thing because I really wanted it to work. Be smart, don't buy this thing. You've read the reviews I should have, now move along!!

Great product for monitoring temperature anywhere in the world. The first one worked so well I bought a second. Now I know if I need to worry about pipes freezing in the winter. Easy setup and great value. Maintains connectivity.

This product absolutely helped keep an eye on my humidity in my plant room! Best part was I could see metrics (temp/humidity) from the office/grocery store/or just sitting on the porch. This device tells you a history of the day for your temperature and humidity via the INKBIRD app. Although I haven’t had many problems. Only “issue” I had was the app sometimes read the humidity at over 600%! It most definitely wasn’t under water. I’m guessing the app will get an update soon to alleviate the minor bug I’ve found. The battery is the star of the show! I received this device w a charge of 76%. I did not charge to 100% and the hygrometer worked for almost 1.5 months! AMAZING!

I bought this item to remotely monitor the temperature of our unheated vacation home during colder temperatures so we would know when it was time to drain the pipes to prevent freezing & cracking. I liked the item because of it's WiFi function and the rechargeable battery which many (or all) of similar devices didn't have. I gave it a 3-Star rating because of some problems I ran into while calibrating the temperature & humidity value to a known temperature & humidity display on our digital thermostat. I placed the device right on top of the thermostat to compare the temp & humidity readings. I found that this device needed some calibration to make the readings correlate. While trying to use the Calibrate procedure, I got erratic & confusing operation...I've attached 2 short videos showing my Temperature & Humidity Calibration operation. As you can see in the attached Temperature Calibration video, entering my desired -2 temperature calibration value results in a value of -3.6 after confirming the -2 value. I have found that I need to enter a value of -1.1 to give me my desired Temperature calibration of -2. I triedalso including a Humidity Calibration video but it only allows me to attach a single video. That video shows that while the entered value for Humidity Calibration is retained after confirming (unlike the Temperature value!), entering of the Humidity Calibration value changes the Temperature Calibration value each time a new entry for the Humidity value is made! VERY strange operation! While this operation is very strange, proper calibration can be performed by entering the desired Humidity value FIRST and then entering a -1.1 Temperature value to get my desired -2 degree Temperature calibration. I'm presently working with the Product Support people to determine if the device is defective or whether they all work like that.

I use two of these in my garage to monitor temps and humidity. They are connected to wifi and I have them set to update every hour. I have freezing alerts set in the app. Battery life is great - I have to recharge them every 6-8 months. Very happy with the quality and performance of these.

I have bought several of these and other Inkbird WIFI thermometers. The all eventually lose their wifi settings and I can not get them to reconnect. I eventually purchased another brand that I never have had trouble with.

Easy to set up. I monitor my grow room temperature in the winter to make sure it’s not freezing. In summer to monitor humidity and temperature. Connects easy with the app that is free.
