Out-of-range exception Play/Pause button Roberts i94 via Frontier Silicon integration using Internet Radio

[SpeedyGoneZales]

The problem

I am using a Roberts Radio Stream 94i via the Frontier Silicon integration.
When pressing the Play/Pause button on the media controls, I get error Failed to perform the action media_player/media_pause. Command failed. Value is not in range for this command.
This only happens in mode "Internet Radio"
This integration uses afsapi.

What version of Home Assistant Core has the issue?

core-2026.2.3

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant Container

Integration causing the issue

frontier_silicon

Diagnostics information

I can stop playback like so:
curl "http://<IP>:80/fsapi/SET/netRemote.play.control?pin=1234&value=0"

However, I cannot start playback using the same approach.
To start playback, it seems necessary to select an item from the navigation list, which starts playback:
curl "http://172.22.55.30:80/fsapi/SET/netRemote.nav.action.selectItem?pin=1234&value=7"

The way to do this seems as follows:

1. Get the name of the current station like so
   curl "http://<IP>:80/fsapi/GET/netRemote.play.info.name?pin=1234"
2. List all saved stations like so:
   curl "http://<IP>:80/fsapi/LIST_GET_NEXT/netRemote.nav.presets/-1?maxItems=500&pin=1234"

This returns an array with the station name and preset ID:

<item key="7">
<field name="name"><c8_array>BBC WorldService</c8_array></field>
<field name="type"><c8_array>IR</c8_array></field>
</item>

3. Match the name with the station name, extract the key, and select that for playback, like so:
   curl "http://<IP>:80/fsapi/SET/netRemote.nav.action.selectItem?pin=1234&value=7"

Session IDs will preserve the navigation status, e.g.

session=$(curl -s "http://172.22.55.30:80/fsapi/CREATE_SESSION?pin=1234" | awk -F'[<>]' '/sessionId/ {print $3}')
curl "http://172.22.55.30:80/fsapi/SET/netRemote.nav.state?pin=1234&sid=${session}&value=1" #Set navigation state #Enable Nav
curl "http://172.22.55.30/fsapi/LIST_GET_NEXT/netRemote.nav.list/5?pin=1234&sid=$session" #Get item 5 from list

Anything in the logs that might be useful for us?

Logs show the following exception:

Additional information

I'm thinking the best course of action would be to store the station name and correlating ID as a state in Home Assistant when the user first selects the station to play, and retain it after playback is stopped. When the start button is then pressed, the ID can be recalled from the HA state.
BTW: The API also offers the image of the active station in the graphicUri endpoint, this could be underlayed on the media player similar to how other media player integrations do it.

Some other calls I observed used by the UNDOK app:

/fsapi/GET/netRemote.nav.currentTitle?pin=1234
/fsapi/SET/netRemote.nav.action.navigate?pin=1234&value=0
/fsapi/LIST_GET_NEXT/netRemote.nav.list/-1?maxItems=25&pin=1234
/fsapi/SET/netRemote.nav.action.selectItem?pin=1234&value=0
/fsapi/GET/netRemote.play.caps?pin=1234
/fsapi/GET/netRemote.play.info.providerLogoUri?pin=1234
/fsapi/GET_NOTIFIES?pin=1234&r=21648&sid=1402866871

Your proposed solution is very brittle: it doesn't work if you are listening to a radio station that is not in the presets.

[SpeedyGoneZales]

The word "preset" is misleading. The only way to play a station is to choose it from a list. This list can be provided using the browse function (via Airable or a 3rd party solution like Radio-API ), or indeed it can come from the presets as in the presets button on the Radio itself.
Whereever the list comes from, the API call above ("preset") refers to the position of the item in that list (0-indexed).
It is not possible to directly play a station by URL (at least I haven't seen that functionality in the API, and the 94i certainly does not support it).
The only potential snag I have run into is that the API pages responses into sets of 40 each. Right now, I am not sure how long the session retains the selected set of 40, but if we assume it's forever, then the approach would work.

[wlcrs]

I've implemented browsing through the Internet radio directory in the underlying https://github.com/zhelev/python-afsapi library, but it's far from stable in practice.

I'm not inclined to build a workaround based on an unstable piece of code.

If you're able to figure out how to make browsing through those Internet radio-directory stable, then I would appreciate a PR on that repository.

Besides that, I also don't see how the integration would be able to restart playing a random internet radio station that was selected by the user on the radio itself. The integration wouldn't know where to find that station in the directory. It's not feasible to scan every menu in the directory.

I'm having a look, but FYI, the async_tests.py also throws errors for forward:

Status: None
Start play succeeded? - True
ERROR:root:Traceback (most recent call last):
  File "/Users/toby/python-afsapi/async_tests.py", line 128, in test_play

Set power succeeded? - True
Version: ir-mmi-FS2026-0500-0515-Stream94i_V2.14.35c.EX86167-V1.04

The two observations I have made so far:

• Navigation is tied to a session ID, and the radio remembers the state of navigation (it seems until the next power cycle)
• List items will list wherever the station was selected from, e.g. a subfolder in the radio navigation or the preset list.

I don't feel very nimble navigating folders right now, the netRemote.nav.action and netRemote.nav.action.navigate endpoints don't behave like I expect them to.
If we could get access to the Last listened folder, the task would be easy, because we could just pick the top entry to make the Play / Pause operation work.

[SpeedyGoneZales]

I had a little facepalm moment earlier.
To both Stop and Start the playback of an Internet Radio station, you run

http://<IP>/fsapi/SET/netRemote.play.control?pin=1234&value=0

That's it!
It'll remember the last played station across power cycles or switching modes.

[wlcrs]

Hey @SpeedyGoneZales , thank you for the PR. I've left my remarks there.

Apart from adding a stop function, you're solving the problem on the wrong level in that PR. It's better if we adapt the integration instead to correctly set the attr_supported_features of the player depending on the mode. That way the HA interface can also display the correct buttons depending on the mode of the player.
