I am trying to link the dim level of a (z-wave) device to that of another device. The master device is called DownstairsLight1, the slave is DownstairsLight2.
I created a task which has just one "Change Property" action. It should set the value of DownstairsLight2.Dim Level to %%DownstairsLight1.Dim Level%%.
However, when I use the substitution syntax as described in the help file (above) the value is replaced with '0' after I click OK.
Unfortunately, when setting the 'Value' in a Task, the substitution only works for Alpha-numeric type properties (not Numeric types like the dim level).
You'd probably have to do it in a script (with a task to call it when the dim state changes). It's a hack and a pain, but it should work.
