The colorpicker in the iOS app seems to have bugs.
When I select a color, countless requests are sent to the HUE Bridge. (Milliseconds)
The HUE Brigde also raises a mistake. Look in my logfile.
The whole thing only happens with the iOS app in for example BasicUI these errors do not occur. Setting a sendFrequency also brings no success.
I have tested it with 2 different or rather 3 different lamps. Innr RGB Bulb and Phillips RGB Bulb on openHAB 2.2.0 and with the Tradfri RGB lamp under openHAB 2.1.0 (and still under the old iOS app.)
Is that the same with you? If so, I would create an issue on Github.
