OWN OpenWebNet Language Reference
The OpenWebNet protocol was defined in 2000 by Bticino to specify the communication with a Bticino domotic gateway, connected via LAN, RS-232 (serial) or USB.
Basic Syntax Rules
A Bticino gateway receives and sends OPEN messages:
- A message is a simple string, containing the characters asterisk (*), hash (#) and numbers from 0 to 9.
- each message begins with an asterisk (*) and ends with a double hash (##).
- within the message, fields are separated by an asterisk (*).
Example: *field1*field2*field3*...fieldN##
The following table shows the allowed syntax:
Message Type | Message | Note |
---|---|---|
ACK | *#*1## | Message accepted/understood |
NACK | *#*0## | Message not accepted/understood |
Standard | *WHO*WHAT*WHERE## | Standard message |
Status Request | *#WHO*WHERE## | Request a state (e.g. if a light is ON or OFF) |
Dimension Request | *#WHO*WHERE*DIMENSION## | Request a dimension |
Dimension Write | *#WHO*WHERE*#DIMENSION*VAL1*VAL2*...*VALn## | Write a dimension |
