You can create a True/False variable -
kitchenLEDOn and a rule to turn the light on/off based on this variable’s value.
kitchenLEDOn value is changed to True, or when it is changed to False
kitchenLEDOn is True, turn the light on, else turn the light off.
Then add this variable to the dashboard so you can tap it to turn the light on/off and set the icon/color based on its value accordingly. Then in your original rule, add an IF_Condition and only automatically turns off the light when
kitchenLEDOn value is False, which means the light has not been turned on manually previously.
