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?
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.
