Change device assignment?

I want to do some changes to my device assignment in the spark, but I can’t get it to work.

If for instance I try to assign my current chamber temp sensor as a beer temp sensor, or if I try to unassign it; I do the changes and hit the Apply button, but it doesn’t work.
If i refresh the device list it still has the old configuration, I have restarted the spark as well as the raspberry, but it still has the old settings.

I have no problem changing the target temp from the web interface, so I am connected to the spark. I also do not seem to get any error messages when hitting the apply button.

You have to set the function to None and then click apply. I know, an uninstall button in the web UI would be a good idea.

works!, thank’s ones again.
