Review: Works well - revised review 8/10/22 - 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.
Review: Great room temp/humidity monitor - 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.

### ⭐⭐⭐⭐ Works well and have good range but need to register lower temps.
*by S***N on January 2, 2025*

I bought two of these for my chicken coop and greenhouse. They are accurate and easy to connect and use. These have been invaluable for monitoring temperature. However they do not register below 32° which is thier only downfall. Being wifi has a huge advantage over the Bluetooth ones I tried using before.
