Well. The Era 100 just arrived yesterday. It took me about 20 Minutes to figure stuff out and my "Toddler sleeps" automation finally runs completely with #HomeAssistant without any hacks.
I guess, every time a #HomePod annoys me, I just buy another #Sonos now, sell the HomePods and move on.
The way HomePods work these days, this should take about 40 Minutes. 😅
But seriously. I wish that my previous experience with Sonos wasn't that bad. The I would've probably tested this out months ago.
Thanks to @motoridersd for testing my use case in Home Assistant before buying Sonos again. That made it much easier for me.
