How to create a template who randomly choose one of the playlists listed?

I tried this:

'{{ state_attr("sensor.playlist_sensor", "items") | list | random }}'

But i get this error:

TypeError: 'NoneType' object is not iterable

Sorry, maybe the answer is really simple, but i still have many difficulties creating templates…

You’re trying to access the attribute with the name items, but there’s no attribute with that name.
Here are the templating docs in case you didn’t stumble across them yet.
Something like this should work:

{{ state_attr("sensor.playlist_sensor", "playlists") | random }}

If you just want the uri:

{{ (state_attr("sensor.playlist_sensor", "playlists") | random)['uri'] }}

@fedot

{{ (state_attr("sensor.playlist_sensor", "playlists") | random)['uri'] }}

Thanks for the precious infos, but using that template i get:

TypeError: object of type 'NoneType' has no len()

[fedot]

Alright, does

{{ state_attr("sensor.playlist_sensor", "playlists") | random }}

work at least?
If not, what’s the result of

{{ state_attr("sensor.playlist_sensor", "playlists") }}

In the template editor?

[maurizio53 (Maurizio Fabiani)]

@fedot

'{{ state_attr("sensor.playlist_sensor", "playlists") }}'

In the first case the result is the same, in the second i get ‘None’

[fedot]

Are you sure the entity_id is correct?
Since your friendly name is “Playlists sensor” I’d assume the sensors id is sensor.playlists_sensor instead of sensor.playlist_sensor
So maybe try again with

{{ state_attr("sensor.playlists_sensor", "playlists") | random }}

or

{{ (state_attr("sensor.playlists_sensor", "playlists") | random)['uri'] }}

depending on what data you need.

@fedot

{{ state_attr("sensor.playlists_sensor", "playlists") | random }}

Yes, you’re right, my fault… It confirm my still poor knowledge…
The second template is what i need, thanks…

[maurizio53 (Maurizio Fabiani)]

@fedot

{{ (state_attr("sensor.playlists_sensor", "playlists") | random)['uri'] }}

Using this template i get in the developers/tool models

uri: spotify:playlist:6R2R0VEqvpLdbUgOPMMY4I

How to toggle the ‘uri’ voice? If i use this in a script i get

uri: uri: spotify:playlist:6R2R0VEqvpLdbUgOPMMY4I

[fedot]

Even in the template editor you shouldn’t get uri: ... in the output, something’s wrong…
Are you sure you’re using the one with the [‘uri’] part?
Maybe try double quotes?

{{ (state_attr("sensor.playlists_sensor", "playlists") | random)["uri"] }}

[maurizio53 (Maurizio Fabiani)]

@fedot

{{ (state_attr("sensor.playlists_sensor", "playlists") | random)['uri'] }}

Ok, thanks again, in this way all is working good…[quote=“maurizio53, post:10, topic:421053, full:true”]

@fedot

{{ (state_attr("sensor.playlists_sensor", "playlists") | random)["uri"] }}

Ok, thanks again, in this way all is working good…

Have been looking for something like this. Could you please post the config for the sensor definition? Thanks
