I'm trying to add a custom wind sensor; I'm able to change modify an existing one and change the name of the sensor, its picture, and the description, along with modifying the names of the sensor's existing attributes (i.e. Caption and Value). However, I'm not seeing any way to add an additional attribute. For example the existing sensor has 3 attributes (wind direction, speed, and a diag code.) I need to add two additional attributes (sensor temp and heater status).
It looks like I can manually edit the .SCU file to add these, but is there a way to do it from the ShortCut GUI?
