i think he's about that his cec do not work,so when pi starts the TV is not switching ON .
lets wait what he says Wink

RE: turn on on tv with cec - rana - 21st May, 2013 05:06 PM

first of all thank you for the echo "on 0" | cec-client -s
and rikardo1979 im sorry if my msg is not clear

so now you know what i want to use it for how can i send this command from my http or tcp i hope it makes sense what im trying to do

RE: turn on on tv with cec - mk01 - 21st May, 2013 08:23 PM

you can always call xbmc build in functions by accessing xbmc through web interface or json, and I'm sure there is build in function to run system command, but for this case it unnecessary complicated.

of course it depends on the system / machine which is triggered by the movement (change in picture on your cam), but to run the command remotely you can always do like:
Code:
ssh xbian@my_xbian_rpi_ip "echo \"on 0\" | cec-client -s"
of course you would need to configure to be able to login without password, what is possible by removing xbian password and allow sshd to accept zero passwords, or by generating rsa key pair.

or via xbmc http and build in functions http://wiki.xbmc.org/index.php?title=List_of_built-in_functions by using System.Exec("echo \"on 0\" | cec-client -s")

there is broad scale of possibilities for this one and depends on all the devices used in this "chain" of events starting from the cam and ending by turning on the tv

RE: turn on on tv with cec - rana - 22nd May, 2013 02:33 AM

i dont think im doing this right

http://192.168.0.2/jsonrpc?request={"jsonrpc":"2.0","id":1,"method":"System.Exec("echo \"on 0\" | cec-client -s")

but i get
{"error":{"code":-32700,"message":"Parse error."},"id":null,"jsonrpc":"2.0"}
what im i doing wrong?

Thank you rana, you must have been adding your past while I was deleting mine. :-)
I have done as you suggested and I get the same DEBUG message(s) The TV is not turning on via the remote at this time.

I guess we just have to wait on one of the experts to help us out then

RE: turn on on tv with cec - rana - 25th May, 2013 05:05 PM

i tried making a addon so i can call the addon to run the script to turn off the tv didnt have any luck anyone want to look at and let me know what im doing wrong

here is the addon.xml file

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<addon id="service.script.tvoff" name="Tv off" version="0.1.0" provider-name="RaNa">
<requires>
<import addon="xbmc.python" version="2.1.0"/>
</requires>
<extension point="xbmc.python.pluginsource" library="off.py">
<provides>executable</provides>
</extension>
<extension point="xbmc.addon.metadata">
</extension>
</addon>

and here is the off.py

import os
os.system('echo "standby 0" | cec-client -s')

jsonrpc doesn't implement system.exec function, but old http does. go for it.
and btw: you can't have quotations ' " ' inside other ones. so you need to use something like " xxx yyy \"inner quotation\" text continues" and you miss "}" at the end as well. so if system.exec would be implemented, the command would look like:

Code:
http://192.168.0.2/jsonrpc?request={"jsonrpc":"2.0","id":1,"method":"System.Exec(echo \"standby 0\" | cec-client -s)"}

not sure why its not working

if you want to check whether the script is at least started as you are expecting, start some test command like that:

os.system("echo $(date) >> /home/xbian/file.txt")
