Event Handling in Blockly

[harrykausl]

Hello,
I have a switch which controls the status of a dummy switch. switch on - dummy on, switch off - dummy off. I handle this by events in blockly. Now I want to switch the dummy switch in domotic, the status of the switch will be changed, but I don't want the first event to be handled. Is there a possibility to say, I want an event only, if a switch is changed by blockly and not by user?
