Continuing the discussion from Motion controlled lights, Best practice?:
I think there has been discussion previously on this list; but I’m using a basic Chromecast binding by ibaton: https://github.com/ibaton/Chromecast-Openhab-Binding
I found some minor updates were required to work with my Chromecast - mainly updating it to use the latest version of the underlying Chromecast Java library. You can find my updates here: https://github.com/engineergreen/openhab/tree/chromecast-binding
Having said all that, I’ve noticed the openhab wiki has a sample of how to control a Chromecast from openhab via a command line program and the Exec binding, though I haven’t experimented with that yet.
