I've got a Disk Free sensor that is currently in the Down state as it's below the error limit of 10% free space. However I wish to lower this error state to 5%. I've clicked on the settings of this channel and set the lower warning & lower error limit for the sensor but the sensor still reports "9 % (Free Space E:) is below the error limit of 10 % in Free Space E:". Just for testing, I tried to set an upper limit and this does affect the graph (I can see the yellow and red colours appear at the top of the dial).
I presume the sensor is pulling in the settings via inheritance but I thought editing it would break inheritance. Any ideas?
