Me too I have a question how could I invert the state?
Your solution defaultState:'LOW is not working as this only changes the initial state of the chip’s outputs, so its will only set when it boots to stay in LOW or HIGH state.
This parameter is not for inverting the logic.
I was trying to invert the logic by using transform in a sitemaps ex.: Switch item=A1 mappings=[OFF=ON, ON=OFF] , but is not a perfect solution for me because many things:
the icon logic will be still inverted
also the graphical sliding switch will be changed to ON OFF buttons by using transom
furthermore the log is also is reporting On during Off which may lead to confusion.
