Pass payload to serial plugin?

[aalmans]

Hi,

I am using VoxCommando to send events to EG and this works really well. This way i control my LG TV with specific serial commands such as:

ka 0 1\r (serial write command to turn on the TV from standby)

The question i have is how to pass variables from  VoxCommando to EG. I would like to use this to set the volume to a specific level. I can generate an event in EG such as:

Broadcast.tv-setvol '10'

I just don't know how to pass the variable "10" to the serial command:

kf 0 {eg.event.payload}\r

What do i need to replace {eg.event.payload} with to have the variable "10" passed on to this serial command so it reads: kf 0 10\r  ??

Thanks for your help!

Hi aalmans.  Welcome to VoxCommando.

{eg.event.payload} is correct.  If you try it with EventGhost's osd action it should work.

The problem is that the plugin you are using is probably just passing the {eg.event.payload} as a literal string instead of replacing it with its value.

To solve this you should be able to write a single line of python script like this:

eg.plugins.Serial.Write('kf 0 '+{eg.event.payload}+'\r')

you can paste the following code into your eventGhost tree to test it:

Code Select Expand


<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="1544">
   <Macro Name="Python Script" Expanded="True">
       <Action>
           EventGhost.PythonScript(u"eg.plugins.Serial.Write('kf 0 '+{eg.event.payload})+'\\r')")
       </Action>
   </Macro>
</EventGhost>

Thanks jitterjames!

Cannot try if it actually works as i am still waiting for my USB-to-RS232 cable to arrive but thanks for the help so far! Didn't realize you could also write python scripts. Good to know...
