The 1920 has 4 ZPs directly wired to it. The 1810 is at the end of a drop from the 1920. On the 1810, I have a Connect attached, which also has a line in from the media amplifier. The Connect also provides sonosnet connectivity to a pair of Play 3's and one Play 5 that are too far from the switch/ZP area.
To get the setup working, I disabled wifi (sonosnet) on the 4 wired ZPs and enabled STP on the 1920 and on the 1810. I set the priority of the 1920 at 4096 and the priority of the 1810 as 8128. The system is operable (no diabling broadcast storms), but the Connect is showing up as root on the Sonos STP, not the HP 1920. My understanding is that the MAC of the 1920 should be the system root. In the 1920 diagnostic file and on the 1810 configuration page, it appears that the 1920 is root - it's just in the Sonos STP output that the 1920 is not root.
In screenshots below, 40b9-3c8f-929f is MAC of the 1920.
