HE + Pandora + Chromecast Audio Groups

How can I use HE to start/stop a Pandora station to a Chromecast audio group?

I've tried copying the URL from playing Pandora station on web into the play track URL on Chromecast but nothing happens. I assume I need some authentication step out information.

On my previous SmartHome setup (Vera + Reactor) I had music start and stop based on arrival, departure, awakening, sleeping, and even changing stations based on weather conditions. Desperately missing it and feeling antiquated using an old Android phone and my fingers ever time lol.

Hmmm... Install the google integration app. Then create a virtual switch attached to the play attribute? Then write you're rule to define presence and then hit the virtual switch? That should work

Yeah I have the Chromecast Integration app installed and all devices (and most importanly, groups) have all been discovered properly and I can interact with them.

Haven't thought about leveraging Virtual Switch, but that's a good idea.

The part I'm missing is the 'play attribute' - I have no idea how to get Pandora to start playing a specific station through any of this. Currently, if it's started manually from a phone I can use the pause/play/stop all successfully. But nothing to initialize the stream and casting...

TIA for any help!
