What is the easiest way to link to channels, so that changes of Item A get reflected to Item B? For example I have a light switch that has a status LED and would like to link it to the light that it switches. I am using 2 Items there to keep my items file more clean, I could of course directly connect it to the main channel but this keeps my configuration simpler as I have the switches in a seperate file.
Of course I found (Why) is linking two items complex? already, which uses rules (and that would have been my first approach aswell), is there a simpler way to do it though, if I remember correctly I read about a "bind"or link binding a while ago?
