No Devices Found

This issue occurs when no Sonos devices are discovered by the Crestron Home system.
Issue(s)
No Sonos devices were found during the Sonos discovery scan.

Explanation
When a Sonos discovery is initiated, a two-stage discovery process begins. In the first stage, a
multicast message is sent out on the network. The Crestron Home system gives Sonos devices
30 seconds to respond. If at least one device responds during this interval, discovery is stopped.
On the Sonos System Settings screen, a "Multicast Success" message is displayed.

If no devices are discovered during the first stage, a second multicast message is sent out on the
network. If no Sonos devices respond within 30 seconds, a "No Devices Found" error is raised.
The Crestron Home system provides a notification of this issue on the Diagnostics screen.

Diagnostics Screen - No Devices Found

Tap the gear icon next to the Sonos System gateway to view the Sonos System Settings page
with the About tab open by default. A "Household Not Found" status is indicated for System
Connection Failure Reason.
