Howdy, I've got a C-8 Pro that I just updated to 2.5.2.129 to fix some issues with the Sonos Integrator migration. It took 5 or 6 power cycles to get the hub to come back up, and when it finally did, this is what I see. The Sonos app is absolutely destroying the hub resources - I have a ton of Hub Load Severe warnings and don't really know what to do about it other than disable the app.
How many Sonos players did you bring into the integration?
9 discovered 4 imported since a bunch are bonded surround sound pairs. So there are 4 I can “use”
I have 10 imported and 15 discovered, and while it it's the top resource user, I'm not seeing any resource warnings. So I doubt it's exclusively the Sonos integration, but I will profile it.
