Python Plugin: Spotify

[Sjaakios]

This plugin will use the spotify API's to start playback on your spotify connected device. A spotify premium account is required!

Having some time between project, i've decided to learn some python... So i'm far from a professional so it can still be buggy, let me know if you run into any issues. I've tested this having domoticz running on my Synology Nas, running version 3.8153.

Code + installation steps can be found here: https://github.com/DaanJJansen/domoticz-spotify

Let me know what you think.

ps. if anybody knows a better solution for the one off manual action to get the authorisation code from Spotify, i'm all ears.

Thank you for developing this plugin. I tried to get it started on my Synology DS918 + with Domoticz version 4.9700 today.

Until now no device has the following output:

Error: (Spotify) Error calling 'http: // localhost: 8080 / json.htm? Param = getuservariables & type = command'
Error: (Spotify) Can not read the uservariable holding the persistent variables.

Maybe I made a mistake but I think everything is correctly filled in at Spotify including http: // localhost

This error is about not able to reach your domoticz system, it's trying to fetch some user variables. Is this the correct url + port to reach domoticz?

Hi,

Now I could add it, and a new switch appeared. The value of the switch is changing, it shows the current spotify device (phone, or PC). Can you help me how to use the user variables? That is not clear for me.

Hi, I'm having troubles retrieving the code. After entering the code I get this in the logfile:

Code: Select all

Error: (Spotify) Bad request to spotify, code entered in hardware parameters could one be used once. Please get a new one

Any ideas?

You could update the user variable with your search string + type of search. Where type of search could be 'artist', 'playlist', 'track', 'album' and the search string is what you want to search.

E.g. update your user variable with 'artist coldplay'. After update, press on the new switch the spotify device (in your case phone or PC) on which you want to listen to coldplay.
Playback should start.

Error: (Spotify) Bad request to spotify, code entered in hardware parameters could one be used once. Please get a new one

Hmmmmm... The code can only be used once to retrieve an access token. Did something else went wrong with the plugin before? Try getting a new code from spotify and try again.

To validate, spotify redirects you to http://localhost/?code=AQ......Cusmbo right? You've entered 'AQ......Cusmbo' in the code parameter?

ps. corrected the spelling mistake in error msg.....
Error: (Spotify) Bad request to spotify, code entered in hardware parameters could one only be used once. Please get a new one

[Egregius]

Yes, I'm redirected to (just changed some of the numbers)

Code: Select all

http://localhost/?code=AQDDgWQ2tTz1ErSgQ_jkty4Viz7ZA7cpTKV01KRrZW5vdLd-CZ01uKPeESo5OJE36i1hMYPAhvhuCjtTY31Ukr3OUt_IzWKUMiDARF1UmHa2b8RnXjLJFkIIiJ5k9r3Uv11AcVofaWbxDoFFy-EwZ2gXRY6m49p7j3PPhIV_tz-2-jDzpXSicy_29nJVE_vIaua-Ydut8nYS-zvws9jkYalM0PNMrvqbjkX1EpPAj3werhkeddEbN07o1Wg

and then I past the 251 characters as code in the settings page

I didn't used the plugin yet, just came across this topic

[Sjaakios]

And you tried getting a new code, and enter this accordingly in the plugin?

Meant with using the plugin, it ran befor (e.g. already a call made to spotify using the entered code, making the code invallid as it can only be used once)

[Egregius]

Yes, already tried 5 codes. The plugin never worked, it instantly drops the error in the logfile.

[Sjaakios]

Hmmm, ok... weird

I've updated the script to provide some more debug information to get a better clue on what is going on.
The request that is failing is making a post call to spotify with your client_id, client_secret and the code. I've made the error more precise so we can see what code spotify is returning. Error code 400 means the client_id, client_secret or code is incorrect.

So if you would, please update your code with the latest version on GIT and PM me the debug log (as it will contain your client_id and secret).

Hmm,

just installed the spotify plugin ...
The handling on the api went as expected.

I get a "Cannot read the uservariable holding the persistent variables" error in the logging right after (re)starting the pluging from the hardware menu
It does not give any devices

Any seggestions ?

This error is about not being able to read the user variables from domoticz. It uses url + port set in hardware parameters.
In your log, is there also a line with:

Code: Select all

Error calling 'http://xxxxx/json.htm?type=command&param=getuservariables'

Can you validate from the machine running domoticz, that you able to make this call?

[eddieb]

Hi,

I am running domoticz on Syno .. http://IP:8084/
I will try to run that command later today.

suggestions ????

[Sjaakios]

ahhh do you have user authentication enabled for domoticz?

[eddieb]

No, not from 127.0.0.1 ...

[Sjaakios]

and changed port in spotify hardware parameters to 8084?

[eddieb]

As you see ...

the error from your curl command is because request is incomplete...., somehow stripps the last query parameter. Try:
curl -v -L "http://127.0.0.1:8084/json.htm?type=com ... rvariables"

When i execute this on my Synology, i get a list of variables
