Another option I have been working on is grabbing an image from any website to display on an eink screen. At the moment i am using the inkplate 6 but the concept should work with any eink screen. Its not really HA-specific but as it’s been mentioned in a few threads i have put a tutorial online at:
The inkplate 6 also support HA in the latest update, its a lovely screen, has an esp32 built in and deep sleeps, a new 10inch one is available via their crowd funding page, ships in May. Mine has been running on a battery for 14 days now, updating every 15 mins.
Hope this helps some people,
Andy
