I have attached two pistons. They both ‘should’ do the same thing. If I turn the table lamp switch on it should fire a log to console. However if I use the physical device/attribute it works perfectly. If I use a device variable from an expression it doesn’t fire. Matter of fact, even thought I am using a trigger as a comparison it doesn’t subscribe to any events? It I try to subscribe the if expression it still does not fire?
What am I missing?
Thanks
