Saving a list of urls within a template sensor as a string

[123 (Taras)]

@jolaca

it seems that keeping the result as an array of JSON, it is no longer limited to 255,

That’s unlikely. The developer documentation specifically says it is always converted to a string:

You can store anything you want in the state, as long as it’s a string (will be converted if it’s not).

Attempts to store more than 255 characters in state will result in an error message:

Need help storing URL for use in generic IP camera (over 255 chars)

I am trying to use the RESTful sensor to get and store this URL each minute, but unfortunately the URL returned is longer than 255 characters, and therefore it is not storing. Instead I get this error: Invalid state encountered for entity id: sensor.cam_1_url. State max length is 255 characters. Is there some other method I can use to store this URL to be used as the still_image_url: in the generic camera platform? …
