run once at keypress but not again at keypress

My TV only have a Power Toggle command.

I created a "Start System" macro which turns the tv on, switch to the right input etc.
When i press this button again, the tv turns off - not good.

My thoughts are, make a phyton script with a branch if a variable is set (system already on)
and terminate the macro "Start System".
If the variable is not set, then set the variable and execute the macro.

Question is, how is the right syntax of the script - if this is the right way to do it.
Perhaps there is a better way.

There really isn't a good way if the only IR signal is power toggle. However, a lot of TV's have discrete on/off signals, even if the remote doesn't include the button. I would check remotecentralfor your TV and see if they have more codes.

This answer is not the way for me.
There is no other command, and i want to use EG to deal with the problem.

in the autoRun put a python command:

Code: Select all

eg.globals.TVisON="false"

make a macro with python script:

Code: Select all

if eg.globals.TVisON=="true":
    eg.plugins.EventGhost.TriggerEvent(u'Event_If_TV_is_on', 0.0)
else:
    # here you need to switch the tv on 
    eg.globals.TVisON="true"
    eg.plugins.EventGhost.TriggerEvent(u'Event_switch_tv_on', 0.0)

note that this code is not tested
but this is basically it!
good luck!
