WIIM Mini stuck on solid green light – unresponsive

[rgrbk]

Hi everyone,


I’m having trouble with my WIIM Mini. It seems to be completely stuck: the device only shows a solid green light and doesn’t respond to any button presses (short or long).


I’ve already tried the following:

• Unplugging the power for a longer period – it goes through a restart cycle but always returns to a solid green light.
• It doesn’t show up in the WIIM app and is not connected to my Wi-Fi network.
• Based on another post I also tried a different power supply, but that didn’t solve the issue either.

At this point it feels unresponsive and I’m not sure what else I can do.
Does anyone have suggestions on how to recover it, or is this a case for warranty/replacement?

Thanks!

Try another power supply with more power.

Was this device previously working fine?

Thanks for your reply. I tried but it did not help. What is minimum power you advice?

Yes it was, but I haven't used it for about 1-2 months. I suspect after starting it up again, it updated and now I have issues.

I think 2.5A is recommended.

• Based on another post I also tried a different power supply, but that didn’t solve the issue either.

To elaborate on HGO's message above, it's not just about different PSU, it's about making sure it delivers enough power.
I forget what the requirements were (you can find that out from this here forum), but if you have a PD rated or a Quick Charge brick, they should deliver enough for trying if this is the problem.

I used an PD3 labeled off brand one I had laying around for traveling purposes (USB PD 3.0 is atleast 5V, 15W/3A, but probably 30W/3-5A).

EDIT: ah, you were quick, while is was typing this out, you practically resolved the issue I was describing

Yeh but the device was working fine before. So it's unlikely to be a power supply issue that just randomly occurred now?

Especially when it's powering on as well?!

Thanks for your reply. I tried but it did not help. What is minimum power you advice?

The recommended power supply is 5V 1A, and I have been using power supplies which meet this spec with my Mini's for more than 18 months without any issues.

There are some indications that the latest firmware has some peak power uses when setting up WiFi. This may cause issues if the used power supply is just enough to run it in normal case.

Hi all, thanks for the great support! I checked my power supply and it is rated output 5.0v/1.0A/5.0W. As said, it worked perfectly fine before.

Do you have another power supply to try, perhaps one with a higher current output, to see if it improves things.

I had a USB-C laptop charger. probably a bit overkill, but at least powerful enough. It shouldn’t damage the unit.
In any case, it powered up and worked again. It even performed a firmware update, which I hoped would resolve the issue.


Now I’ve tried another USB charger rated at 2A, but the problem persists. It’s really strange because it used to work perfectly fine.
At this point, I think I have no choice but to order a separate, more powerful charger, maybe 5A or even 10A and hope that’s sufficient to run the unit.

Your discussions on this power supply issue seem unthinkable to me... even if, following a firmware update that would lead to higher consumption, it originally consumes less than 300mA... so... but especially if that's really the case and were to increase considerably... the real concern would be about the viability of a mini in these conditions... but even simpler, it can be measured in a few seconds with dedicated USB plugs for a few euros... practical in many circumstances...

If this is really the case, Wiim must react quickly....

 

[canard]

(I gave my minis around me otherwise I would have checked it , need 10 secondes...but damn...it's at wiim checking that s in first...but maybe we just shouldn't expect "MIL" reliability from these little products ;-))) )

 

[rgrbk]

So I bought a new charger, 3A 15W and now it is back working again. For now I'd like to flag it as 'solved'. Thanks for all the help!!

 

[canard]

Your story is worrying... and need fast reaction/ investigation from wiim.
there is a "bug"...

 

[canard]

Ps
with latest firmware + peq, analog output 2v (and with its akm card which is suspected of being quite power-hungry), a pro plus ....
< 0.7A (< 5.1v)

(In previous measurements, the mini was not even halfway... your mini should be measured as is... Regarding the charging types: fast, ultra-fast, normal? What are the voltages provided?)

At peak or in average? The OPs issue may be at boot only where the power needed may be much higher. This has apparently changed with latest firmware?

If you find the situation normal, not requiring serious investigations...
Answer of wiim?

(ps in the case of the pro plus...no overconsumption at startup...or even a little lower....moreover, even a correct 1A transformer would support occasional overconsumption ... problem of tension?)
