PS - backticks DONOT work. I have never faced this issue - Maybe because we dont use US kbd? I have tried all combinations. We use qwerty UK kbd. Its frustrating - Why use some obscure backtick which cannot be even used by not american keyboards
Thats what you should use. With version changes old threads will become invalid.
As for the trigger itself: in the automation you cann see if a trigger is being activated.
If you send an 1 to the knx group 7/6/1 does it show as triggered on the automation?
And in the developer tools, what was the exact trigger you saw?
