The OpenWebNet protocol was defined in 2000 by Bticino/Legrand 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
