Xiaomi Gateway custom MP3

[Egregius]

Hi All,

I'm trying to upload a custom made MP3 to my Xiaomi gateway to be used as notification sound.
Took a while to figure out that I needed a Android device to do that, iOS only support recording voice messages.
Anyway, the voice recordings work, the uploaded MP3 works, but plays at double the speed getting a voice like the Chipmunks.
What are the requirements for the MP3?

i guess 128kbs - 44.1khz, mono (or maybe stereo also works)

when you say it plays at double speed, i think it has something to do with the sampling frequency of the audio file.
try to update its file to 44.1khz, and upload again, or try to upload a 22khz version..

i'm not sure the exact reason its double speed, but in here its working perfect!

With wich program did you create the mp3?

[BarryT]

FL Studio
But it can with every program as long there is a mp3 encoder in it.

Actually it is not mp3, but aac
(have tried mp3 directly, gateway doesn't play it)
64k aac is ok.

(I believe miHome makes conversion via xiaomi's cloud when accept mp3 in application, but I've tried directly uploaded file)

Need miio (any flavour - php-miio, python-miio, etc.) and available gateway token and IP (token you can look in mihome, at page where you switch on developer's mode).

1. Convert the source mp3 into aac for gateway:

Code: Select all

ffmpeg -i 18Track.mp3 -b:a 64k tr18a.aac

2. Place converted file into place available from gateway by http (m.b. other proto works also; didn't check).
I used webserver on my router; but it is also possible to make it available via dz (however it doesn't return correct mimetype for aac, but downloading via it still works).

3. Via miio with correct ip/token send the command:

Code: Select all

{"id":1,"method":"download_user_music","params":["5001","http://192.168.1.150/media/music/tr18.aac"]}

Here first param is musicID, must be >=1000. Second is url where gateway will take the music.

4. Periodically check the progress (since donwload command is async):

Code: Select all

{"id":1,"method":"get_download_progress","params":[]}

It will return progress for each music ID in %. Finally you'll take:

Code: Select all

{"result":["5001:100"],"id":1}

5. Play the music. There are two possible ways: by MusicID (which is string), or by index (which is numeric). In first case you can also set the volume

Code: Select all

{"id":1,"method":"play_music","params":[5001]}

Code: Select all

{"id":1,"method":"play_music_new","params":["5001",10]}

Now you can set MusicID as the custom variable and play/stop it via existing xiaomi gateway buttons. In MiHome this record will be nameless.

Other useful commands are

Code: Select all

{"id":1,"method":"get_music_info","params":[0]}

- get list of available music (params m.b. 0,1,2 for 'system' banks, >2 will return list of user music).

Code: Select all

{"id":1,"method":"delete_user_music","params":["5001"]}

Code: Select all

{"id":1,"method":"get_music_free_space","params":[]}

- returns available bytes. On 'fresh' gw it is about 11Mb available.

Could you eleborate step 3? "Via miio with correct ip/token send the command"

What is the command to connect to the gateway with miio? I cannot figure it out. Tried both miio and python-miio, but there is just no good documentation how to run the commands correctly.

[klirik]

As an example:

Code: Select all

php miio-cli.php --ip 192.168.1.123 --token 3XXXXXXXXXXXXXXXXXXXXXXXXXXXXX22 --sendcmd '{"id":1,"method":"get_music_free_space","params":[]}’

Actually I've just wrapped all this long thing into a 1-line script which takes the command and add all this long stuff before it, like

Code: Select all

#!/bin/bash
php miio-cli.php --ip 192.168.1.123 --token 3XXXXXXXXXXXXXXXXXXXXXXXXXXXXX22 --sendcmd \'$1\’

and invoke it as

Code: Select all

./gateway "{"id":1,"method":"download_user_music","params":["5001","http://192.168.1.150/media/music/tr18.aac"]}"

but this is already small details, you can guess your own comfortable way
(say, auto-increment 'id' param - it is ok to have one and same for gateway, but, say for mirobo it will not work. Encode 'method' as separate, and leave only 'params' hand-coded).

It doesn't work to me at all. I don't know what I'm doing wrong.
My aac file is located on my RPI: /home/pi/Sounds/0001.aac and I've socond copy on dropbox.
If I execute command:
php miio-cli.php --ip 192.168.1.XXX --token XXX --sendcmd '{"id":1,"method":"download_user_music","params":["10003","https://www.dropbox.com/s/7v6ixits5dwrc7k/0001.aac"]}'
I receive: Устройство 192.168.1.XXX доступно и ответило:
{"result":["ok"],"id":1}
Looks like everything is OK, but aac file is not uploading to my gateway.
DevType is 1066.
I don't want to upload files using mic in my iPhone because of poor quality of the sound. Can you help me somehow to do it using cli?
