I suspect it'll be something with resolution of my images? I've tried 758x1024 and 768x1024 px both with the same results. I did nothing special to images, just exported them out from Figma. I'm nearly there, maybe I'm missing something? Thanks! Last edited by workbee; 09-11-2025 at 08:20 PM. |

Oh, that's... interesting. The script just uses "eips" to update the image - info here: https://wiki.mobileread.com/wiki/Eips - syntax is "eips -f -g {imagefile}".
A fair bit has been said about the PNG format sent to the Kindle. The HA Kindle screensaver add-on (separate from my extension) has this to say: https://github.com/sibbl/hass-lovela.../main/index.js - near the bottom, lines 302-326 It indicates the PNG output to be greyscale, bit depth 8 (that is actually somewhat unusual these days - creating a greyscale PNG specifically using 8-bit coding), with dithering and various other transformations that apply to the image, not the file format. With that, the missing piece may simply be to make it an 8-bit PNG, whereas most PNG output today is 24-bit color or higher. Not sure if that's the whole problem, though. Rendering it twice is oddly suspicious, but one render could be coming from "linkss" rendering (which may be smarter), with a duplicate coming shortly behind it by the "eips" renderer called by the script. If rendering it as an 8-bit PNG doesn't improve things, maybe upload an example file? Also, unrelated - but I only noticed late in the game (while charging my Kindle for the week), that my newly improved extension will never update the screen while it's charging... it's entirely event-driven and focused on battery life above all else. It's better to cycle a battery than to keep it charging all the time anyway! (nervous laugh)... yeah, maybe I'll find a way to work "plugged-in" updates back into it in the future! It'd need to bring some self-timers back into the game, a bit ugly... but it might work. |

Kindle PaperWhite 7th Gen
After about 2 weeks of faffing about with Haas-Lovelace-Kindle-Screensaver and the online screensaver extension on my Kindle Paperwhite 7th Gen.
I finally found the avhm version (Page 9, Post#125 of this thread) and it works just fine. Just need to get the Home Assistant dashboard right now |

Kindle Paperwhite PW6 not waking up?!
Good evening,
I wonder if anybody has managed to get this working on a Paperwhite 2024 (PW6/12th generation)? Basically, I am using this version: https://github.com/64bits/Little-Lan...nescreensaver/ I made some slight adaptations here and there but nothing wild:
For testing purposes, I set the update interval to every 10 minutes. Also, I disabled the Kindle's power saving mode in order to prevent any WiFi/connectivity issues. Taking a look at the log file, that doesn't seem to work though and it seems that the Kindle fails to wake up properly. This is my observation for now:
