WiiM Pro and RoomFit failure

[musictechwriter]

I'm really enjoying my new WiiM Pro but cannot get RoomFit to analyze my room. I have tried rebooting my router, WiiM, and phone as well as clearing the app cache (Google Pixel 7 Pro), but the same thing happens every time. After I start the analyzing, the generic error page displays instantly, 3-4 seconds before the chip and sweep tones play. Then, apparently the WiiM is continuing to try to use the mic, because the green Android mic indicator continues to display until I completely close out the app. Tech support is trying to assist but no joy yet. So, has anyone else encountered this same problem, and how was it resolved? Thanks!

Hi
Could you post a screenshot of the error screen here?

This might be a silly question, but is microphone permission granted to the WiiM app? (Typically, Android displays a dialog if an app doesn't have microphone permission.)

Something similar happens here today. WiiM Ultra, WiiM Pro Plus, WiiM Pro same result.
Enter Roomfit set frequency range in the cog menu go back, click next…Nothing Happens.
WiiM restarted, app closed, phone restarted no change. It is as if the next button is completely disconnected.

I ran Ultra RoomFit on an Android phone and found no issues.

Is the WiiM app the latest version (3.4.12)?

Yes. I’m on WiiM app 3.4.12.26012418
I’ve since discovered Roomfit is working on the same devices but using a 2015 iPad which doesn’t support the lastest OS. Must be an issue with some iPhones. I’ve since seen another posting from someone else who has the same issue.

Tech support sent me a new version of the Android app today. I haven't been able to test it yet but will do so tomorrow.

I tried RoomFit again this morning after installing the APK Android app that tech support sent to me. Now the RoomFit process makes it through listening to the chirp and sweep tones, but now I get the unable to connect to server error. So no RoomFit equalization so far. I rebooted everything (fiber optic modem, router, WiiM, phone) and tried again and got the same unable to connect error. Could there be some sort of weird geographic restriction occuring? I am in Costa Rica. The primary reason I am hoping to get RoomFit working is to clean up the muddy bass and mid-bass of my powered speakers (pair of Edifier 2850). I have it a little better using the parametric EQ, but I know the RoomFit can do it much better.

Tried again this evening. Same thing -- cannot connect to server error.

So this is a mystery to me. I have tried with everything on the VPN (USA node) and everything off the VPN, but there's no connection to the RoomFit server. Should I try to put everything on the VPN for a different country entirely??

Infortunately I can not assist with this exact issue, but will add that WHEN u get this working - set the low freq range for the room fit (settings) at 500Hz. This is because your smartphone device mic and eq is voiced for - voice. It can not handle sub audio freq. Result is the Wiim may create an eq with overboosted low end.

500Hz? Do you mean 50Hz? If you set the low frequency limit to 500Hz there is very little point in using RoomFit at all.

I am sorry for the mistake. I meant to say upper limit. Most room acoustics issues (standing waves/boomy bass) happen below 500 Hz. Above this "Schroeder frequency," the room behaves more predictably, and your phone mic is likely to introduce errors rather than fix them

Ok, this creates another question. I don't have access to a USB-C measurement mic, but I have a small shotgun mic that I can use with an adapter. Even though it's not calibrated, would that be better than the Google Pixel 7's built-in mic?

Shotgun mics are designed to be highly directional so aren't ideal for this kind of measurement. Directional mics often have severe bass roll-off, and the most important part of the spectrum for room correction are low frequencies. Mic directionality at higher frequencies might make the measured response seem wonky, but higher frequencies shouldn't be corrected using RoomFit anyway, so that is not such a big issue.

That being said, if your shotgun mic has a published frequency response chart in its specs/datasheet, you can try to trace it using e.g. the WebPlotDigitizer tool and import that as a calibration file in RoomFit settings. That should improve accuracy significantly.

Whether this would work better than the mic in Pixel 7 is really hard to say. Typically phone mics have a resonance/peak around 8kHz (looks ugly but is not that important for RoomFit), and unknown amounts of bass roll-off below 50Hz (this can be an issue).
Unfortunately the only way to be confident in your measurement (and resulting RoomFit correction) is to use a properly calibrated measurement mic (e.g. Dayton Audio iMM-6c is pretty affordable, and the miniDSP UMIK-1 is a de-facto standard in this hobby).

Yes. I’m on WiiM app 3.4.12.26012418

I was beginning to think this was a networking or phone settings issue until I discovered some more odd behaviour in these recent versions of the WiiM app for iOS.

First of all Roomfit is still working on my network on a 2015 iPad running a slightly older version of wiim home.

Secondly, the last three versions of wiim home also don’t work for sending logs or feedback to WiiM from my iPhone 14 Pro, limiting the support options.

Finally. I have one of my WiiMs, a pro plus with several Roomfit profiles saved, causing a Show All button to appear on the Roomfit screen. Clicking the edit icon beside a profile doesn’t work on the initial Roomfit screen and rerunning Roomfit is also not possible. BUT, after clicking on Show All, the edit profile and reevaluate buttons work successfully on the resultant screen. iOS 26.2.1, iPhone 14pro, wiim home 3.5.1.26021110.

If the not-functioning wiim home Roomfit features do work from a different but rarely available screen in the same app on the same network with the same wiim device and phone, I don’t think it can be my router or phone settings. Something must have changed in the app to cause it to stop working from the main Roomfit screen. I’ve shared this with customer support via email several days ago but as yet haven’t heard from them.
