The OpenWebNet protocol allows a "high-level" interaction between a remote unit and Bus SCS of MyHome domotic system.
An OpenWebNet message is structured with variable length fields separated by the special character '*' and closed by '##'.
It characterizes the domotic system function to which the OpenWebNet message is referred.
Example of status: light ON, active alarm, battery unload, etc.
Example of dimension: sensor temperature, loudspeaker volume, firmware version of a device, etc.
