Nice add-on to be able to “hide” some inputs I’m not currently using

How do you hide the inputs? Through the app/ through the Wiim UI? I can't work it out... Might be stupid, or maybe the UI just sux!

Through the app. Check you have the latest? I had to update to find this functionality.
"Browse" screen. Manage sources, like Manage music services.

Ok thanks... I was looking in the device Audio Input menu, not on the browse screen.

They should do the same for outputs too! I only use Line Out and Headphone.

That would diminish your joy over an UI «that sucks» even more. Are you sure that’s something you want?

Yeah that's right... A UI that doesn't suck so much!... Fix the new Wiim Ultra radio browser, it's useless. Have option for grid view in app and Wiim Ultra, ability to config font size, it's tiny and doesn't respond to system font size (on Android) etc etc... The UI for both the Wiim Ultra and App could be great, but sadly they are very poor!

I think that's a rather harsh assessment. Yes, it can improve, but it it still functional. The radio brower is not perfect, but it far from perfect. I finally got the update today, and I was pleasantly surprised with the radio browser and having all the local radio options right there.

You can access it on the home page on the Ultra screen.

The name "widget" is a bit misleading I think. It is just menu page on the Ultra screen.

It do however not contain anything useful. At least not in my country with my setup.

(And the background of the home page is still ugly and not matching the rest of the look and feel.)

Thanks! I never see it, as my screen is always off.

Very same thing in Italy: I'd like to recall my preferred radio stations directly (they are: Rai from Italy, RTSI from Switzerland, Antena 1/2/3 from Portugal). It'd be nice to put a radio link in a list!

Eagerly waiting for a direct access to USB disk content...

You can easily set those stations in Browse > Music Services > Open Network Stream and then for each station set it as a Preset the readily available in the Favorites tab.

There are too few Presets for that.

Anyone have anything in the "local radio" outside US?

Nope.

12 radio stations not enough?

12 radio stations not enough?

If only used for radio stations, then maybe?

Thank You So Much! I’m going to try.

My "Local radio" is empty (I'm in Australia)
My "Top iHeartRadio stations" is empty.
I'm also seeing "BBC Radio" in the top level menu, but that's of no interest to me.
"Popular Music Stations" is the only one that has stations showing.

Wiim your "radio stations" is pathetic. Who tested/developed this? They should be making the coffee instead...

I'm in Australia and no local radio stations!

You're right, 12 presets it not enough.. How about 30. It would take Wiim 10mins to make that change.

Wiim hardware is great... UI/UX is terrible!

Been a while since we had an “it’ll only take 10 mins” or “it’s a one line change” comment

 

[Ronnie D]

It's already available.
Open network stream has 28 places for radio urls as far as I can remember.
Then there's tunein
Then vtuner
Iheart radio
And radio paradise
And probably more

Sure dude... unless you have some hardware limit or your code is "spaget"... just do this const int NUMBER_OF_PRESETS = 30;
But, seeing how poorly implemented your UI is I imagine your code is a mess too!
