Notes

Device is not reporting with decimal points precision

It's been reported by several people that this device does not report with decimal precisionopen in new window.
Even though the device has the option to set the number of digits after the decimal for both temperature and humidity, it does not report with decimals. So unless IKEA chooses to fix this with a firmware update, this will not work.
