Imo this is a bug and not a feature.
The Roam is from what I understand, by design, waking up when the Sonos client/app is put to the foreground. When awoken the battery starts to drain, resulting in the orange led flashing every other day or so.
My issues:
- Imo auto-wake should be a setting, most people are happy to press the buttons instead
- Auto-sleep is clearly not working or the wake/sleep/wake sequence needs allot of power optimizations
- In our household the two roams also wake due to background activity of the Sonos app, so without actually opening the Sonos app. Not sure if this is related to activity of our 5.1 ARC setup?
- I need to reset the Roam pair as stereo-pair everytime this happens.
