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. Here you'll get a brief overview of the OWN language syntax. To watch live the OWN messages of your Bticino gateway, you should try the Python Monitor in our Code Snippets section.



Basic Syntax Rules

A Bticino gateway receives and sends so called 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##

Allowed syntax of OWN messages:

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)
Attribute Request *#WHO*WHERE*ATTRIBUTE## Request attribute value
Attribute Write *#WHO*WHERE*#ATTRIBUTE*VAL1*VAL2*...*VALn## Write attribute value(s)

Standard Message

In the table above, we learned a Standard Message consists of *WHO*WHAT*WHERE## .

  • WHO identifies the service, such as scenario, light or automation
  • WHAT is the action to be performed, such as light ON/OFF or dimmer, shutter up/down etc.
  • WHERE identifies the object, which can be an area, group, an environment, or just a single light or shutter etc. A WHERE field can also come with optional parameters, separated by a hash (#), e.g. *WHERE#PAR1#PAR2#...#PARn

Some Examples

*1*0*25##           Turn off light 2.5 on local interface (e.g. F
*1*1*47#4#01##      Turn on light 4.7 on interface 1 (#4#01)
*1*1*0415##         Turn on light 4.15 on local interface
*1*0*0##            Turn off all lights on local interface
*0*13*19#4#06##     Launch command 13 of Scenariolist 19 (e.g a F420 is addressed by 19) on interface 6
*2*1*91#4#03##      open (1) shutter 9.1 in on interface 3 (#4#03)
*#4*#1*#14*0225*3## Set heating zone 1 manually ON to 22.5°C
