I have a very simple configuration that adds a button to play a local radio station that uses m3u8:
- type: custom:mini-media-player
entity: media_player.suite_speaker
artwork: cover
info: short
shortcuts:
buttons:
- name: Eldorado
icon: mdi:radio
type: music
id: http://estadaohls-lh.akamaihd.net/i/estadaohls_1@301351/master.m3u8
How can I add a second button with a TuneIn radio station ?
Thanks
Still same issue… 
Actually it seems to be a google chrome problem. It works on my ipad with safari, and on my android with edge and firefox but NOT on my computer or android tablet running google chrome? :o
Just installed the latest release and added the play_stop option, but when running the card and pressing the stop button i get the following:
Fallita chiamata a servizio media_player/media_stop
Is it my fault in something or what?
I’m not sure about tuneIn, but to add another button, just do like this.
Media content is platform dependant so the id, type and even supported sources may vary between components.
- type: custom:mini-media-player
entity: media_player.suite_speaker
artwork: cover
info: short
shortcuts:
buttons:
- name: Eldorado
icon: mdi:radio
type: music
id: http://estadaohls-lh.akamaihd.net/i/estadaohls_1@301351/master.m3u8
- name: Second station
icon: mdi:radio
type: music
id: http://example.com/radio.m3u8
Clear cache maybe? Works as expected for me on Chrome after the latest update (which had the same issue as you had before).
Is it possible that your media player doesn’t support the stop service, what component is it?
Yes, I can add more buttons but can`t get them to play from TUNEIN.
Does anybody have a sample config of Mini Media Player playing from TUNEIN to a Google Home?
Check this, it’s from 2017 but might still be relevant:
media_content_id would be the id and media_content_type would be the type in the shortcut.
Found the issue, I tried update using the HACS. But apparently that did not work.
So i did a manual update instead using the latest mini-media-player-bundle.js.
And now it works!! Perfect… Thank you Very much for your help! 
Great!
The resource reference for the card changed in HACS a few months back so if that was the problem you might have to update it (if you want to use the card with HACS in the future).
Yes, you’re right, it seems this option doesn’t work on amazon echo show… tried another media player and this works!
Can someone help me get the grouped cards working? Im trying to follow the example in the docs (see below) but Im a bit confused. The initial multi-room player…how do I create that? Right now, I have 3 seperate sonos speakers in different rooms that I would like to group together.
- type: entities
entities:
- type: custom:mini-media-player
entity: media_player.multiroom_player
group: true
source: icon
info: short
hide:
volume: true
power: true
- type: custom:mini-media-player
entity: media_player.kitchen_speakers
group: true
hide:
controls: true
- type: custom:mini-media-player
entity: media_player.bathroom_speakers
group: true
hide:
controls: true
- type: custom:mini-media-player
entity: media_player.bedroom_speakers
group: true
hide:
controls: true
- type: custom:mini-media-player
entity: media_player.patio_speakers
group: true
hide:
controls: true
It is pretty obvious in the ha source what services the player supports.
The example you’re looking at is simply displaying how you can group several mini media player cards into “one card”, it’s just a layout example and won’t provide any extra features or functionality.
See the Speaker group management example instead, I think that’s what you’re looking for.
Can anyone help with the shortcut buttons on this card:
I was hoping to add buttons to select “sources” that I have set up in my SkyQ component.
I have buttons that work with this code, where switch.skyq_bbconelounge will make bbc one play on sky
- type: custom:button-card
entity: switch.skyq_bbconelounge
show_entity_picture: true
show_name: false
show_icon: false
show_label: false
show_state: false
styles:
card:
- padding: 0px
img_cell:
- justify-content: start
entity_picture: "/local/images/remote/bbconefaded2.png"
And the config for the sources is this:
skyq_bbconelounge:
value_template: '{{"off"}}'
friendly_name: 'BBCOne in the Lounge'
turn_on:
service: media_player.select_source
data:
entity_id: media_player.skyq
source: 'BBCOne'
But no idea what option I need in the media card for “type” and for “id”
Thanks
This shortcut would do the same thing as your button, but I don’t really see the need for the switch, as you could just call media_player.select_source directly.
- name: example name
type: service
id: switch.toggle # or turn_on, not sure which one you want.
data:
entity_id: switch.skyq_bbconelounge
And if the media player entity of which source you want to change is the same as the card entity, you could just do:
- name: example name
type: source
id: BBCOne
Thanks. I am happy to not use the button, I just could not get the source to work. Will give that a try when I get home.
Ok I tried the new resource reference and that dont work for me. I need to use local reference for it to work right now… 
If you’re still on an older version of HACS the “old” resource url might still point to the correct location.
You can easily figure this out by navigating to the card in HACS and check what resource reference is stated there.
Otherwise try reinstalling the card in HACS and if that doesn’t help consider opening an issue in the HACS repo.
I will check this out!
One more thing, is it possible to make the full artwork image clickable to move to a specific url in lovelace?
Something like:
tap_action:
action: navigate
navigation_path: /lovelace/3/
Currently no, but could add the tap_action option in the future, it’s been requested before and can be tracked here:
