Display jpg-file on epaper

Hi,

I want to display the album cover on a waveshare epaper of the current track, played on my media_player.

I use a text-sensor to retrieve the url from the image. With node-red I copy the jpg to the directory “/esphome/picture”. When I use this way (docu) then the image is compiled and static. How can I link the file and the display shows the new content, if the file is changed? Is it possiblie?

Thank you
Matthias

I’m not sure it fetches the images from the LAN.
I have a feeling it’s flashed in to the device.

You could try with giving it two images to switch between every few seconds, then power it with a power bank and get out of range.
If it still displays the images then it will not work, I think.

It won’t update. And an epaper isn’t a good device to display an album cover. So I’ll use it for typically information like artist, track and album.

Did you find a solution to this problem? I’d like to display images too but as far as I understand it is not possible.
