For a few years I’ve had a Sonos device in my kitchen, that has been monitored by a script on a Raspberry Pi. If the Sonos is playing, it turns the amp on & sets the input etc.
If someone turns the TV on, that overrules Sonos and sets the amp accordingly.
This morning, Sonos was playing as usual - but the amp wasnt.
A bit of digging and it looks like my Sonos had an update (now on S1 / 11.2.7) and the info that was used by my script (http://w.x.y.z:1400/MediaRenderer/AVTransport/Control) is no longer available.
I tried https to 1443 with the same path and that fails with the same UPnP 401 error.
Is there somewhere else I can pull the current status from via a url or similar?
