+1 for Humidity and Filter features.
I have two CT101. One of them does not work from the webUI, but works from the app and LCD.
The first one had this problem. I had to remove it and add it again and it seemed to work.
My first one that works across all three (web, ios, LCD) is CT101, but it does not have the flashing lights on the left of the display).
My second one that works across only two (LCD, ioS) is also CT101, but it has flashing lights on the left of the display.
So apparently there are two devices with the same model no.
