Figure 1. - A test picture taken by Rpi with OpenHAB when pressing a door bell.
I've been using Raspian Wheezy built on NOOBS 1.3.9 and today I ran a sudo apt-get update to synchronise it with some other Raspberry Pis and it broke things.
In particular the Pi Camera utilities stopped working.
This was resolved by running sudo apt-get upgrade.
This downloads a whole heap of files and takes a while to apply the upgrade but now the Camera works again!
I could be imagination it but since the upgrade;
I've noticed that NOOBS was upgraded to 1.3.10 and the Raspian Wheezy is also updated both dated around 9 Sept 2014.
With IE11 - The openHAB classic UI pages are devoid of any Push buttons and can their display can cause havoc to the events table.
When displaying the page I was receiving zillions of push button events.
As soon as I shut the page down and restarted openHAB the issue went away.
No such problem exists with Firefox. (Nor iPAD)
