You should use label = weeWX field name
in your map. You can avoid having a field map if each label in your file is the same as a weeWX field name. I have no idea whether you can have weeWX talk directly to your arduino. I would expect there is no reason why not. You would certainly need a driver and quite possibly code to run on your arduino as well. I am not aware of any such driver, though others may know of something. GRy
