Sending DCE events from command line

There is a utility in pluto (/usr/pluto/bin) that allows sending proper DCE message from command line. If you want for instance to trip motion sensors on/off you can achieve this in simple way (ID means ID of particular device that you send event for) :

Event "tripped on"

ID -1000 2 9 25 1

Event "tripped off"

ID -1000 2 9 25 0

Event "temperature changed"

ID  -1000 2 25 30 temperature_value

Event "output on"

ID  -1000 2 28

Event "output off"

ID  -1000 2 29

Event "light on"

ID  -1000 2 48 10 1

Event "light off"

 ID  -1000 2 48 10 0

For instance -

A. tripping security sensor with ID of 195 to ON :
/usr/pluto/bin/MessageSend dcerouter 195 -1000 2 9 25 1
B. play media (/home/public/data/tts/0.wav) on Xine player with ID of 44 :
/usr/pluto/bin/MessageSend localhost 0 44 1 37 29 "" 41 "" 42 "" 59 "/home/public/data/tts/0.wav"
C. report that light with ID of 210 is ON :
/usr/pluto/bin/MessageSend dcerouter 210 -1000 2 48 10 1

Sending DCE commands from command line

Change HouseMode command : I've sniffed DCERouter logs and this is what happens when you change security state from Orbiter :

But sending this command from command line doesn't work :

/usr/pluto/bin/MessageSend localhost 0 -1000 1 19 5 2 17 7 99 5678 100 0 101 R

Also sending event House Mode Changed doesn't actually change house mode (that's ok, cause events are meant for notifying):

/usr/pluto/bin/MessageSend localhost 0 -1000 2 43 38 0 39 2


I have found out the reason. -1000 is DCERouter address, but this kind of message should be addressed directly to Security plugin - in my case this is ID of 13. I'm following this, although don't understand distinction of -1000 and 13 - if DCERouter is addressed it should relay message to security plugin anyway - so I don't understand why this is necessary - any opinion ?

As far as I can tell, the reason for '-1000' is to allow devices to broadcast events to the system as a whole rather than to a specific device, presumably for event-based devices that do not do a specific function. I shall look more into this... -AVJohn.
/usr/pluto/bin/MessageSend localhost 0 13 1 19 5 6 17 7 99 5678 100 0 101 R

Now it changes security mode properly... Parameters in this command line are : 0 from, 13 to Security plugin, 1-Type: Command, 19-Command "Set house mode", and the rest:

08      09/11/07 16:06:53.512             Parameter 5(Value To Assign): 1
08      09/11/07 16:06:53.512             Parameter 17(PK_Users): 7
08      09/11/07 16:06:53.512             Parameter 99(Password): 5678
08      09/11/07 16:06:53.512             Parameter 100(PK_DeviceGroup): 0
08      09/11/07 16:06:53.512             Parameter 101(Handling Instructions): R


Other interesting DCE messages

Will parse the meaning of DCE messages below in future. Just wrote it here to remember....

It seems like "Goto Screen" command

/usr/pluto/bin/MessageSend localhost 0 64 1 741 10 "Whatever" 159 53 9 'A message|Ok|Remind me later' 137 '-targetType device <%=!%> 15 1 67 13 "/root/Something.sh" 51 "--answer yes"|-targetType device <%=!%> 15 1 67 13 "/root/Something.sh" 51 "--answer no"'

To display Text Alert on Orbiter :

/usr/pluto/bin/MessageSend localhost 0 20 1 809 9 "Text to Display" 70 "alert" 182 "30" 251 "??"

Also interesting command is #397 "Show popup", but I have yet to discover how to use it...

Does anyone know how to display popup with question and few answer buttons (yes/no for example) ? Can this be done without Designer to create screen - just to specify question, texts on buttons and actions on click ?
