FR: Picture entity of last generated/send picture

[emufan]

Wouldn't it be a good thing to have a picture entity in each device of the last generated picture?

So one can see the generated one (test mode) in HA and not only in file system and one can have a dashboard of the current pictures of the devices as well.

Your FR was implemented with the latest release

@jonasniesner Fantastico! Thx a lot. Unfortunately I have no camera entity in my device. :-( Can I provide something for finding the reason?

BTW Only for interest, why did you implement a camera and not a picture entity? I'm not an expert here, but always try to understand why something has been done this and that way.

[four2six]

for me the entities are created like camera.<000etc>_cam , but they don't show an image

[jonasniesner]

@four2six did you call draw custom after the update. It will only show newly generated images and not fetch anything from the AP at the moment

[four2six]

Yes, I did. Just found the images under config/www/open_epaper_link/ .... does this folder have to have be configured in the allow list for external directories or something?

[emufan]

Here, unfortunately, I don't have any of the camera entities. The images are now (additionally) generated in www folder, etc., but no entities.

I have deleted the integration and re-added. Still the case.

This the only related part in the log:

Oh, sorry. Cams seem to be there yet. But not bound to sand so no visible in the devices. Sorry, only looked there as for the other entities.

So I have still the errors in the log, but no picture in the cam, same as four2six. Even if new generated and send.

[emufan]

Next feedback. It is there, but not displayed, because the ID-part of the filename is expected in uppercase, where it is generated in lowercase. Perhaps depending on file system, but here it is case sensitive. So it is not fitting at the moment, the generated image to the url, which is bound to the cam. If I rename it to uppercase, it is shown.

But as said, not bound to the device. And I wonder if an image-entity would be better than the cam. But that it not that relevant.
