I got a XIAO 7.5" ePaper Panel (early build) while it was on a flash sale from Seeed Studio. This is something you can make yourself, but I took the lazy route.
After playing with it for a little bit, I’ve got a nice battery powered eink display that shows a bunch of Home Assistant entities. I think it looks good and it replaces several of those LCD displays that come with temp probes.
When I first got it I thought I was going to have to build what’s displayed using YAML in ESPHome Builder, but then I read about the Puppet add-on and decided to give that a try instead. Much easier! You just have to create a dashboard in Home Assistant and get it to look right on the 800x480 B&W display. That was the hardest part; getting it to display nicely in B&W. After a bunch of card_mod changes, I got it to look pretty good. I’m still tweaking it, but I’m happy with what I have now.
The big unknown is battery life. They say it’ll last 3 months if you refresh every 6 hours. I’m refreshing every 30 mins, so I’m curious to see how long it last. The one draw back to this product is that there’s currently no way to see the battery status. From some reading, I’m pretty sure I can mod it to so battery status is available, but I’ll hold off on that for now. Hopefully the release version has battery status (it sounds like a fairly easy change).

I also changed the icons in the weather card to black and white icons. The default ones work, but sometimes multiple colors blend. I got the icons from icons8.com

Hi there,
Well done!, Looks great! 
We all agree on the battery monitoring thing, and there are a few mod posters so, that’s good. I don’t see My “pirates” on the Baseball schedule though 
they don’t want that heat yet! 
I’m hoping they do a color unit, that would be sweet, and PLEASE keep us posted on the battery consumption… 
and Thanks for the contribution…

It looks like battery life is a little over a month with 30 min refreshes (1 min run time).
