Each DeviceServiceItem can export configuration variables or use configu-
ration variables exported by other DeviceServiceItem. Variables are ex-
ported by adding them to the global variables variable:
variables = {
someVar = 12,
otherVar = 'text'
}
Example file example.item.ex:
item = {
name = "example"
variables ={
}
defaultvariables = {
}
