-# This module can handle JSON and XML data to decode weather data.
-#
-# If you do not have JSON installed on your system or if you CAN NOT install
-# JSON (e.g. on Fritzbox) you MUST NOT deactivate the following "use JSON".
-#
-# Instead, create a dummy file named "JSON.pm" an put it 
-# into your Perl installation directory.
-# This file should contain only one line of coding, that will be
-#
-# 	return 1;
-#
-# After this you can  restart fhem and create an owo device. 
-# You MUST set attribute "owoUseXml" to 1 in this device,
-# before retrieving any data via owo API
