I made a webparser skin for acquiring MAC addresses of associated clients with my wireless router. It substitutes MAC address for real names of devices and shows it when the device is connected to my home wireless network.
So I have six meter groups for every device like this:
But, when the device is not connected to the network, it just shows the text: "Active Client 1:". So if the MeterClientName meter is empty, I just want to hide that group. I tried with IfEqualValue, but it seems it works just with number values. I think there has to be simple solution for this problem, but I still cant find it.
Any string returned from the measure that does NOT contain "Active Client" will be evaluated as "0" by the calc measure. Any string that does will be evaluated as "-1".
