What am I doing wrong?
I’ve invested ~30 hours in googling, trying with combinations of changed, received command, channel trigger… with the variables described at: https://www.openhab.org/docs/configuration/rules-dsl.html#implicit-variables-inside-the-execution-block
So, I have no idea…
I just want to know what is the item that triggered the rule, AKA the item that changed its state.
Thanks in advanced
