  1.0 out of 5 stars Inaccurate and poor display

  I'm very disappointed in this device - the display is mostly unreadable (no backlight and very poor contrast even with new/full battery) though I'm not too concerned about that as I was going to use this outdoors for remote reading. The main problem is that the device is inaccurate. it is off by 0.3C (the device reads 0.3C higher than the actual temperature) which is a lot of error for such an expensive temperature/humidity sensor. I contacted the manufacturer and they said this is acceptable and within spec, and that there is no way to calibrate the device, or compensate in the app/etc for the error. This is a big issue when trying to detect when it reaches freezing outside. I have several other far cheaper temperature sensors that are all far more accurate than this one. The humidity value reads correctly though.
  
  I would definitely not recommend this device (my return window has unfortunately closed), it is not very accurate (esp for the price) and the display is essentially unusable, even in bright sunlight.
