Spotify device is inactive

[TobiBu]

Hi Tim,

I just started using mozilla's web thing gateway and came across your spotify adapter. I followed the instructions to set it up and the little box was ticked after the procedure but now when I turn on the spotify adapter it turns itself off immediately. I guess it it is not properly connecting. Any clue why that might be? It's probably a simple fault of mine as I am just starting with the gateway. Any help would be highly appreciated.

cheers Tobias

Welcome on board!

It sounds like the adapter is crashing. Can you please check the logs for errors? You'll find them at /settings/developer after clicking on View Internal Logs.

Hi Tim,

Thanks for your quick answer! The internal logs say this:

2020-04-30 17:29:31.992 INFO : spotify-adapter: Setting state to true 2020-04-30 17:29:32.110 ERROR : spotify-adapter: AddonManagerProxy: Failed to setProperty state to true for device: Spotify 2020-04-30 17:29:32.111 ERROR : spotify-adapter: { [WebapiError: Unauthorized] name: 'WebapiError', message: 'Unauthorized', statusCode: 401 }

not sure what this means. I guess something went wrong with the spotify authorisation?

I think the access token is expired. I'm currently refactoring the adapter. This may already solve it. Does the problem persist after rebooting the adapter?

[TobiBu]

what exactly does rebooting mean? simply deactivating and activating the adapter again? Or deinstall and reinstall?

[tim-hellhake]

simply deactivating and activating the adapter again

This one 😄

[TobiBu]

nope, that does not work. I'll might try reinstalling and getting new spotify credentials...

A prepared a new update to add some more logs: https://github.com/mozilla-iot/addon-list/pull/810

[TobiBu]

stupid question, how do I install this specific update? not the normal way via add-ons in the gateway section, right?

stupid me, reading helps a lot. Can install version 0.2.3

stupid question

There are no stupid questions. Feel free to ask anything :)

how do I install this specific update?

When I prepare an update I create a new PR in the https://github.com/mozilla-iot/addon-list repo. As soon as it's merged the update is available in the addons section in your gateway. You could also download the build and extract it to the right folder in your gateway.

this is the new log

Thanks. The access key seems to be ok but the API refuses to fulfill the request. I'm not sure why a 404 is returned but it may be related to the selected device. Can you please try to play a song in your Spotify app and pause it via the addon?

[TobiBu]

amazing, that seems to work...

So, the adapter does not open spotify itself? It needs the spotify app to be open on my laptop or phone?

[tim-hellhake]

So, the adapter does not open spotify itself?

If you don't specify a device in the play/pause commands the currently active device is used. I guess if there is no active device the API does not know which device to use. That's why they return a 404.

Another possible explanation would be that there was no device available at all. You can see the list of available devices here. Just click on GET TOKEN and TRY IT. After that, you should see a list of devices on the right side.

It needs the spotify app to be open on my laptop or phone?

The spotify app seems to be only available if it's open. That's a limitation of the Spotify API.

[tim-hellhake]

I'm thinking about creating one gateway device per Spotify device. This way you could control a specific device rather than the currently active device.

[tim-hellhake]

I'm closing this now as the issue seems to be resolved.

[TobiBu]

Thanks a lot for your help! Much appreciated. It seems like you know a lot about developing adapters. What's the best way to get started? I am currently reading through Mozilla's Documentation but maybe you have some more advice?

[tim-hellhake]

Thanks a lot for your help! Much appreciated.

You're welcome :)

It seems like you know a lot about developing adapters.

I created one or two 😬

What's the best way to get started?

It depends on what you would wanna do. There are bindings for Python and JS. I prefer TypeScript though. There is an example adapter written in JS. If you prefer python you need to look at one of the existing adapters.

In order to get the gateway running, you simply need to

1. git clone https://github.com/mozilla-iot/gateway
2. npm install
3. npm start

Open http://localhost:8080 in the browser.

To start developing an adapter:

1. go to .mozilla-iot/addons in your home directory
2. git clone https://github.com/mozilla-iot/example-adapter
3. restart the gateway (stop it and repeat step 3)

After changing something in the adapter you need to restart (enable/disable) the adapter.

If the directory .mozilla-iot/addons does not exist already you may have to install one of the adapters in the gateway ui.

If you have any problems, feel free to ask me.

[TobiBu]

I see, thanks a lot!

I bought the aquara cube which is not recognised by the gateway. I was planning on working on that...

So, you recommend development on the laptop or directly on raspberry?

[tim-hellhake]

It's way faster on the laptop if your pi is not connected to a monitor. If you need the pi because of the hardware requirements it's easier to develop on the pi though.

I bought the aquara cube which is not recognised by the gateway.

There is already an adapter for zigbee devices. You may only need a supported zigbee stick.

[TobiBu]

ah, yeah. Its recognising the cube as a zigbee device. But it does not recognise the different options... So I thought, maybe I need to do the features on my own.

[tim-hellhake]

But it does not recognise the different options

Then I'd suggest you open an issue in the adapter repo. Maybe there is just a little part missing. There is a list of all available classifiers.

[TobiBu]

I'll try that, thanks. It seems someone had already opened an issue about that there.

[TobiBu]

Hi Tim,

ich hab noch eine eher generelle Frage. Hast du auch Erfahrung mit dem voice controller?

Viele Grüße Tobias
