This script is to get live notifications from LiveSplit in Firebot. If you want to control LiveSplit from Firebot, or you only want to poll for data occasionally then you could use LiveSplit Integration instead. But be aware that these scripts don't work together only one or the other will work at any given time.
I did try to get them working in a single script, but I had some difficulty integrating them. If it turns out that more than just me wants to have this script I'll put more effort into trying to get them to play nice.
To use this script copy it into your Firebot Scripts folder and then set it as a startup script.
