This is what I ended up doing: https://community.flic.io/topic/18102/a-flexible-hub-running-on-a-pi-zero

To those who just want to have a button pointed at hardware that lets you run arbitrary code (in python, shell, perl etc) I'm sharing my quick and dirty instructions for executing scripts via a bit of python. It is for a very specific use case, but is probably a timesaver for those wanting to get set up, and has instructions for starting the script as a service.

I'm a user who finds the app too constraining, and the sdk too complex. If you are not a software developer, but can code, this might be useful.

It's almost certainly too brief, but if people are interested then I'll try to make them a bit clearer....

Cheers

How dirty will I need to get my hands to be able to specify IR codes rather than record them? I have a flic IR blaster attached to a Hub LR. I want to emulate a remote that I don't have. What is the best direction for me to head in?

This looks great. My use case is a little different. I want a machine on my network to activate some code when it sees that I am issuing commands to a device via the flic. I have some perl that switches inputs on a device. Ideally the hub would do it, but the this is the quick and dirty way.

Anyway, thanks for sharing. If I get things working I'll give a better explanation of what I'm doing :)

Bump! The Inability of the LR Hub to see Chromecast Audio groups on my LAN means my flics are pretty useless for controlling audio. Is there a technical reason that this is not the case?
