So I spent about 4 hours this afternoon researching and learning how to create an Extension in Chrome with the purpose of turning on my PC Amp when audio starts playing in Chrome.
Which meant I needed to learn how to create plugins, some Java Script, how to store data in Chrome, create some form of UI to store the Hubitat Creator API URL, get requests and subscribing to soudn events in Chrome.
Unfortunately after doing all this, I realised that my amp when powered on from the wall turns on in standby mode, so was a waste of time for this task but hopefully may be useful in the future!
I'm only posting here as if it's useful to anyone or anyone has any ideas of other use cases then let me know and I'll share the basic solution I have!
