Temperature Humidity Sensor with Backit Screen

This is a must if you want to control temp and humidity in a room, I have servers and routers in my house and this is great to monitor remotely, perfect and love it.

This temperature sensor seems to be accurate, easy to set up and able to monitor remotely on your phone. I have an issue where if you set high or low alarms, the SMS texting feature is additional cost. It's not cheep, like $49.00 a year. This sucks because I know there are other sensors out there with free SMS. I will be replacing it as soon as I purchase another. Other than that, all else is good.

Have had no problems using this. On the plus side, it’s accurate, consistent and reliable.But, because it uses WiFi it needs to be plugged in. (Did not come with a wall wart)Big advantage is it can be used in automations you program in Smart Life.There are other devices just as good that use Bluetooth and batteries. They can’t be used with Smart Life. Decide what your application is.

This device is just not accurate. It has never provided a temperature of less than 79.9 degrees. I would not purchase this again. If I could get a refund on this, I would get one, especially since I was relying on this device to manage tempurature control in my home.

NEW EDIT - 9-19-2022 Back to 5 stars *****I installed a large basement dehumidifier with built in humidistat a few weeks ago. The RH sensed by this device is almost always the same as the large dehumidifier’s humidistat. It is within 1 degree of the humidistat. The non-smart sensors were the ones recording inaccurate readings and have been removed. I am completely happy with this device. It allows me to remotely check the humidity level, and works with Alexa as well.EDIT: After 2 months of use, this device’s humidity readings seem to be inaccurate. My 2 other “non-smart” sensors record higher readings than this product. Prior humidity readings from this device were always 1-2 degrees higher, which was fine. I could adjust the alerts based on my experience with this product’s reading. For the last 2 weeks, this sensor’s humidity readings were 2-3 degrees lower than my other readings. As a result, no alerts were issued to me. I need to actually go into the basement and check all three devices. I realized at that point that this device now was reporting humidity levels lower than it previously recorded.I now need to manually check the other device readings, and if they exceed my limits, I need to alert Alexa to turn on my dehumidifiers, thus negating the use of this device.On a positive note, I was able to create a routine in the Alexa app, which would 1) turn on my dehumidifiers (actually the smart plugs to which they are connected), 2) have Alexa tell me “Dehumidifiers on”, then 3) wait 1 hr and 30 minutes, next 4) turn the dehumidifiers off, and finally 5) have Alexa tell me “Dehumidifiers off.”However there is no IFTTT applet which will automate this process so don’t don’t have to tell Alexa to turn on dehumidifiers. Once I get an alert, I still need to have Alexa turn on the dehumidifiers. This is NOT the sensor’s fault. This brand just doesn’t have an applet using IFTTT.I will continue to monitor differences for another month and report back.ORIGINAL REVIEW: Just purchased and installed the device. Temperature and humidity readings are pretty much accurate with other “non-smart” devices in my unfinished basement. Notifications work correctly, as I’m alerted when the humidity level exceeds my target. I like the backlit screen and that I don’t need to worry about batteries dying.I’m currently trying to work with the Smart Life app and IFTTT app to trigger my smart plugs to turn on/off (for 2 dehumidifiers) based on humidity levels in basement. At this point I have not figured out how to create those scenarios. Hoping to be able soon.Currently, once I receive an alert, I open appropriate app and turn on/off the plugs. Once I succeed, the process will be automated.

Hmm it’s not accurate. I have it in the kitchen with Alexa feedback- it’s off a couple of degrees compared to my visual hand held thermometer-but it’s o.k for what I use it for.

I use the Tuya ecosystem almost exclusively. Tuya has some issues with Google Home, but works great with Home Assistant. Tuya local allows local automation tasks and does not depend on the internet. Faster and more responsive.This was compared against a calibrated Fluke meter, and is about a degree off, sometimes two. This is great for home automation.Cons:1-the time the backlight stays on cannot be adjusted.2-the viewing angle is narrow.3-the built in stand is flimsy and broke when my dog accidentally pulled it off the nightstand when she got tangled in the cord under the bed. A few drops of 5 minute epoxy fixed this.Recommended for a good room monitor, but not so much for beginners.

Bought this temperature/humidity sensor in Jan 2025. It worked well initially and connected to my wifi and integrated into HomeAssistant great. However, the temperature/humidity sensor is now stuck at 88.2 F/66% humidity after 5 months. It doesn't change to anything else even when I put it into a refrigerator to see if the temperature would drop...it didn't. So now a got a temperature/humidity sensor that just display a static value after only 5 months!!! For the price, I expected it to last a little longer. Not recommended.
