What's New:
  1. Alarms: Custom labels and up to 32 alarms.
  2. Squeezelite: Disabled by default; enable in Device Settings in the WiiM Home app.
  3. 12V Trigger: Status now shown in the app; supports a one time on/off toggle from the app.
  4. TuneIn: Faster start when playing Apple Music stations.
  5. Multi-room: Improved multicast logic for more reliable discovery/connectivity; reduced stutter when using Bluetooth input.

Bug Fixes:

    • Fixes for TuneIn Radio and certain FLAC files.
  2. Sub Output: Fixed missing bass when the wireless WiiM Sub Pro was disconnected.
  3. Qobuz Connect:
    • Resolved a blocking issue that prevented playback.
    • Fixed a crash that could occur after seeking.
  4. Spotify: Fixed failures to play from the Spotify app’s Recommended lists and Recently Played; also fixed presets that would not start playback.
  5. Amazon Music: Fixed occasional track skips after seeking and a progress bar desync (bar reached the end while audio continued).
  6. Multi-room: After ungrouping, metadata no longer syncs to previously grouped (child) speakers.
  7. Gapless Player: Fixed a near track end race condition that could trigger overlapping/simultaneous playback.
  8. Local Files: Fixed an issue where the app progress bar reached the end before playback finished.
  9. TuneIn: Now consistently selects the highest available stream quality.
  10. Amazon Music: Fixed unexpected stops when using Amazon Music Cast.

Just curious, why the need to disable LMS by default? It has never interfered with my using the WiiM or Qobuz Connect apps. I do understand that it is still available, but am just interested in the reason behind the change. And, BTW, it has been Lyrion Music Server for some time now. Logitech dropped their support some time ago.

It isn't LMS or even Lyrion Music Server... It's a version of Squeezelite, a LMS compatible player. 😊🎶
 
I understand the difference -- I run the LMS (server) on a separate RPi and have the Squeezelite option turned on for all my WiiM players plus another RPi/PcP player. It was the above post from WiiM that referred to LMS -- its not unusual for people to use the LMS/Squeezelite terms interchangeably.

Don’t know but perhaps some people like the ability to disable a feature they don’t use - similar was implemented for Roon recently and there was even a request a while back to turn off DLNA player support…🤷‍♂️
 
Update received, thank you. I'm curious how the new 12v trigger feature works - can someone explain that to me please?
 
If my unit is on beta FW will this update be pushed to my Pro plus? I was on beta 4.8.734445 and didn't get it after 3 days after release.. I just fell back to main oficial FW 4.8.732046 and not getting it either.

No, you must actively go back from the beta firmware to the general availability firmware, first.

You wouldn’t get the update if you were on a beta release.

It has only been three days since this version was announced, so don’t worry that you haven’t received it yet, I’m still waiting for this update, and would expect to receive it within the next few days.

Please be patient.🙂

Do you use a trigger cable from your Pro Plus? I don't currently, but do use one from my Ultra to my Vibelink.
This feature is available on the latest Ultra firmware, but I don't really see the point of it, as the triggering works fine as it was.
 
THANK YOU !!!! The long reported problem with Qobuz Connect NOT working on PRO PLUS is now SOLVED!!! and sounding fantastic with the WiiM PRO PLUS used as a streaming bridge and the HEGEL DAC used for the conversion! It took a while and many hours testing but all is forgotten as the problem is solved and I love my WiiM app/streamer more than ever !

Just wondering which Hegel dac? Standalone dac, or one in an amp?
Don't have a pro plus, but I did prefer my Ultra going digital into the H190 over rca. Not a huge difference, but noticable.

No, and I was curious if this was a new app-based triggering process that somehow worked without a cable instead. Had me scratching my head, and I still don't understand how it differs from the usual cable triggering process.
 
All I can think of so far is, for example, I turn on my wiim and it triggers my power amp to turn on.
But I want to use my wiim for headphone listening so I don't need the amp on, so I can use the Trigger Off option to turn the amp off.
But this doesn't work if music is already playing.

I'm also puzzled by the use of "Once" and "one-time" in the descriptions.
With my ultra / vibelink combo (with no music playing) I can press these two buttons over and over and the vibelink wakes up / goes to standby on each press.

It would be good to understand how wiim anticipated this to be used.

Another update rolls out—choosing WiiM was absolutely the right call! Active firmware updates are what make a streamer truly great. Big shoutout to the WiiM team!

This is how the feature works between my Ultra and Vibelink.

I wonder quite what 'Once' means? Once per time it's powered up? Not got a remote paired with my ultra right now to check if the remote power button classes as 'powering up'.
Just tried pressing the app On button and yes my vibelink light (connected to the ultra) went bright.
Pressed Off, and the vibelink light dimmed.

Side issue, the vibelink hasn't actually gone to sleep for a week or two (can't recall when this behaviour changed) after the additional 30 mins passes, the light is always on dim.

I have just tried it now,

Trigger On Once
Brings Vibelink out of either standby mode...
