Need Assistance: Issues with Reliable Favorite Playback After Grouping

[sa1ier1]

Description

I’m having trouble achieving a basic Sonos workflow. My goal is to:

1. Activate Sonos.
2. Group players into a defined group using groupPlayers().
3. Play a favorite using loadFavorite().
4. Set the volume to a default level.

The players always group correctly, but the loadFavorite() call works inconsistently. Sometimes the favorite does not play at all, even when I ensure the coordinator is used.

---

What I've Tried

1. groupPlayers() First, Then loadFavorite():

• I ensured the coordinator player was used for loadFavorite().
• This approach never worked, even after:
  • Adding delays after groupPlayers().
  • Triggering on the group player attribute when the switch is set to on.

2. loadFavorite() First, Then groupPlayers():

• This method was slightly more reliable, but the success rate is still inconsistent.

3. Retry Mechanism:

• I added logic to:
  1. Wait 5 seconds.
  2. Check if the coordinator is playing.
  3. Retry loadFavorite() if it isn’t.
• Even with this, the results are hit or miss, and I lack confidence in its reliability.

Expected Behavior

1. Sonos activates.
2. Players group into the defined configuration.
3. The favorite reliably plays on the grouped players.
4. Volume on my players sets to a default level.

I’ve included my latest Webcore code for reference. Any insights or recommendations to ensure a consistent and reliable workflow would be greatly appreciated.

Log Walkthrough - Example Showing loadFavorite() taking two times to finally work

Event 1 (11:37:45 AM)

• The piston was triggered when Sonos.switch changed from off to on.
• Condition Evaluations:
  • The conditions for the piston evaluated as true.
• Actions Executed:
  • Volume Adjustment:
    • Volume adjustment commands for Dining Room and Kitchen were skipped due to command optimization (no change was needed).
  • Playlist Loading:
    • The loadFavorite(304) command was executed for Sonos: Living Room.
  • Player Grouping:
    • Players were grouped using the groupPlayers() command for Sonos Group: Downstairs.
• Wait Command:
  • A Wait was issued for 5 seconds, scheduling the piston to wake up at 11:37:51 AM.

---

Event 2 (11:37:51 AM)

• The piston resumed execution after the 5-second Wait.
• Condition Evaluations:
  • Verified that the playback status for Sonos: Living Room was stopped (true).
  • The playlist value (304) was checked and confirmed to have not changed.
• Actions Executed:
  • Re-executed loadFavorite(304) for Sonos: Living Room.
• No additional actions were taken, and the piston completed execution.

I updated my code but still can't get loadFavorite() to work.

I'm including:

• My WebCoRE code.
• The log.
• Evidence that getFavorite() runs successfully, but no playback occurs. Very odd.

Step-by-Step Breakdown of Key Events

1:07:16 PM - Sonos Group Turned On

• WebCoRE detects that a Sonos speaker group switched ON.
• It checks if the system is "stopped" (meaning no music is playing).
• It verifies if a counter (retry attempts) is less than 5.
• Since conditions are met:
  • A retry counter increases from 0 to 1.
  • A command is sent to load a favorite playlist (ID 304).
  • A 6-second delay is scheduled before checking again.

1:07:22 PM - First Retry

• The system rechecks conditions after 6 seconds.
• Since the counter is still below 5:
  • The retry counter increases to 2.
  • The playlist is loaded again.
  • Another 6-second delay is scheduled.

1:07:28 PM - Second Retry

• The system repeats the process:
  • Counter goes up to 3.
  • Playlist command is sent.
  • Another delay is set.

1:07:34 PM - Third Retry

• Counter increases to 4.
• Playlist command is sent.
• Delay scheduled again.

1:07:41 PM - Fourth Retry

• Counter is now at 5, reaching the limit.
• The system stops retrying since the max attempts are reached.

1:07:47 PM - Process Ends

• Since no more retries are allowed, no further actions are taken.
